Hi Guys,

I have a 2.0l Zetec with what I am told is a mk 1 focus coil pack " dont take as gosspal"
It has a 2 pin connector on the coil unit, a sensor on the exhaust etc. Where can I get a schematic for the engine etc so I can create my own?

From my understanding (see the post I just put up) every coil should have a live feed (the voltage required will depend on the coil) going into one pin. The live feed can be common between all coils. The earth is then controlled by the ECU, individually for each coil.

Hi ya,

There isn't a coil etc, just one ECU with all the HT leads coming off it.

I suggest you post a picture of what you are referring too...

Hi,

This is the coil.

So it's a ford coil pack, it has two coils inside. Fords run a wasted spark system so two plugs are fired at once. The plug has three pins not 2. The centre pin is 12v and the other two are switched to earth by the ecu.

The white box has a single pin. It's a 20uf suppressor. The centre pin is also 12v, the same 12v as the coil. It earths though the bracket.

Great stuff!
Is there a schematic for the whole system with the ECU etc?
Should it be a none standard ECU?

What ecu have you got ?

Not really, there are hundreds of pages of them. Picked out a few for you, look for 'Ford Wiring Diagrams'.

Hi,

Not sure yet as I havent found it, guessing its behind the dash.
I am stripping the car and rebuilding it so will be all new wiring etc (I design electrical systems for cars etc as a full time job ;0)
so I would like to draw up a full vehicle schematic and get one of my suppliers to build me new harness etc so a schemtic of what can be done with this engine, that coil pack and what ECU is best to run it would be fab!

There is a sensor in the exhaust manifold, what looks like crank sensor but did seem to have a camshaft sensor connected.

What you have there is a silvertop zetec.

These where fitted to a Mondeo in 2.0 format, the focus came along with a black top.

The ecu in the mk1 Mondeo is behind the header tank. Depending on the age of the donor it could be a 60 pin eec-iv or the 104 pin eec-v. Again depending on age it could have the pats system or not.

To sum up there is no complete schematic due to volume and variety. It would look like spaghetti.

Find out what ecu you have and there is more info available http://www.locostbuilders.co.uk/viewthread.php?tid=179921 but I would think again about a 100%new loom as half the plugs are not available.

Cheers will look behind the dash.
Dont think it has pats as there is no key at present to start it.
New harness is easy for me, all the terminals will be readily available to me so if I can not get a new connector, I will de-pin the old one.

Some more info would help with answers.

Is this a Mondeo ?

What reg is it ?

Hi ya,

Its a kit car I bought and the guy had no idea what he had lol.

Car ran but not sure how well as only saw it on tick over. It has R6 carbs fitted.

Only thing I found so far are:

Crank sensor (I think, located on engine near to bell housing)
Sensor in exhaust.
Coolant sensor (Not sure if for ECU or temp gauge yet)
Coil Pack.

No sign so far of PATS. No throttle pedal position sensor, Cam sensor looked not connected.

Oh no please tell me it wasn't this one ?

http://www.locostbuilders.co.uk/viewthread.php?tid=203412

lol nope not that one. this was a freind that bought one and never got around to doing anything with it.

Hi,

Just found the ECU, its a 12 pin ECS module.

So better to convert it to a 60 pin ECU or the 104?, which is better and is the way to use these without PATS?

Many thanks for your help!

Neither are ideal if you're keeping the bike carbs both do the same thing if running the injection.

It would have to be a very early zetec ecu to avoid the Pats.

97 on gives you obd2
2001 on has dual o2 sensors.

Again more info needed for a more complete answer.

Does it need to be Iva'd ?
If yes what year was the engine made ?
How much do you want to spend ?
How much power do you expect ?
How much skill do you have to fabricate stuff ect ect

Hi ya,

I can make anything, have fabs made etc do no problem.

Hoping to get it IVA.
Power wise, not to bothered, standard type for 2.0l would be fine.

Is there a way to find the age of the engine from the engine it's self?

If keeping bike Carbs, what's the best route?

Yes the engine number will tell you the age. It's down near the crank sensor.

You can look it up on Burton power web site.

If it's made before August 1995 then you don't need a catalytic converter and will get an easier emissions test and will get away with carbs.

After aug 95 you need a cat and have the tougher emissions test. Forget carbs, you need fuel injection. The oem set up sorts this nicely and is very very cheap but there are packaging issues for the inlet manifold. You can make a manifold or you can move the steering column down link and chassis cross brace.
Of coarse if your pockets are deeper there are lots of plug and play bolt on parts. The deeper your pockets the less you need to make and the faster it will go.

[Edited on 19/4/16 by big_wasa]

Fantastic, getting clear now!
I will check out age of engine.

guess that's the biggest issue, pre 95, carbs and Nordiz is good. Or do you think the current ESC with the vac pipe connected be ok?
If its post 95 then need injection etc.

The Esc properly set up will run but I couldn't tell you if it will meet the test. It has a 3D ignition map that is based on an 8v engine where the burn characteristics are differant to a 16v engine.

I can tell you the oem fuel injection will pass the test.

As will other options. But that will be down to mapping.

Hi Ya,

No engine number! No signs of grinding either so no idea.

Other numbers on block are:

I think 04L97

6015
C8S1A

On head I think 958M-6090-CC

Any luck wih them?

I found it lol it was under a lot of crud.

Looks like:

NGA VDZ1130 ?

Do a search on google as there are thousands of photos to show the location.

Ford replacement engines don't have a number. Ford techs where meant to stamp the old number on when changing the engine. As the customer was never going to see it most never bothered.

They rust to the point you can't see it.

Either way if can not prove engine age you will have to pass the post 95 test and fit a cat.

I found it lol it was under a lot of crud.

Looks like:

NGA VDZ1130 ?


Many, many thanks for your help.

November 1997

Last of the silvertops

Damn lol

Looks like a new engine or should I say find an older engine lol.
Not enough room to put the injection back on and no one will seperate the injection off another car.

Unless there is a way to jet carbs, fit after market CAT and map ECU to get through emissions.

Problem is adjusting the fuelling over the Rev range. The carbs will eventually ruin the cat with unburnt fuel. You could try air injection into the cat to burn of the extra fuel.

Iva is somthing like £450 and somthing like £100 for a retest. I would want to be sure.

A pre Aug 95 engine is an even bigger gamble being over 20 years old and desirable for the same reasons you want one. I wouldn't bother.

[Edited on 19/4/16 by big_wasa]

So it looks like bin the carbs or bin the engine or both. Guess its a nightmare trying to fit the injection system and manifold in the engine bay?

I use the oem ecu's. As they start on the button, run well hot or cold and they work well on the road and best of all cost very little even less when you have no mapping costs. Fits fine with manufactured plenum.

I don't think you will get carbs through Iva on a post 95 engine but I am happy to be proved wrong.


Instead of carbs you can use Bike throttle body's and megasquirt.

Dig deeper for jenveys and stand alone management.

Do you think it would be a major job swapping out the 2.0l Ztec on carbs and replacing with a 2.0l Zetec with all its injection?
So if I got a donner car say a 2003, it should all go in?

Would throttle boddies and mega squirt pass IVA on my 2.0l ztec, guess I would need CAT too, so would a donner car and injection, CAT be the less exspensive route?

2003 Mondeo is a Duratec, then you need bell housings and all sorts.

2003 Focus, 1.8/2.0 would be a blacktop Zetec.

If your engine is good use it.

Yes bike tb's and megasquirt can be tuned to meet Iva.

Hell yes oem is cheaper, I can install a Zetec with oem bits cheaper than you would pay for fuel to take yours with tb's to get the megasquirt mapped. But the tb's will give another 20bhp.

So going off I have a good engine, would you throttle boddies and megasquirt is the way to go or get say a 2.0l focus donner car for around £400 would be a better route?

I can find a few Ztec 2.0l focus for betweem £150 - £300.

Me ? Neither.

But I am not you. I buy the bits where I find them and fit them. A scrap Mondeo is worth around £20 at the moment. I would want a years mot for £400

I coblled this together from scrap yard bits for beer money ( on top of engine and box) years ago. That engine would pass Iva with a cat and air filter.

It's not the one I fitted. I build them up as a hobby.

What engine is that in the video?

Most of the cars arnt scrap, they are mot'd vehicles, most engines are stand alone, no wiring or ECU etc so cheeper to buy a car at say £250, take off what I need, engine, ECU, wiring etc and sell the rest for scrap.
A throttle body kit is £699 for all new parts.
The sad part is I have the engine but no one would sell the injection bits :0(

Could use:

Ford Focus Ghia 2.0 l 4 door saloon

What Issues would I have using that engine and ECU etc?

The engine in the vid is the same as yours. A 2.0 Zetec.

I find all my bits via eblag or the scrap yard. But yes if you wanted to go with oem injection a donor car would get you lots of bits to play with. It will need repackaging and the more you make the less it costs.

Wish I could use my engine but not sure how to get all the bits without getting a diner car. I have no intake system at all other than the bike carbs

Just to point out I havnt said you need, or the only way to do it is oem injection. It is one cheap affective way of doing it.

You need to find your self an ecu and the related sensors. Stick to silvertop sensors for a silvertop ecu. And blacktop for a blacktop ecu.

Packaging issues. Assuming we are talking about sticking this in a 7 ? And as its already in there we will ignor sumps and starters and all them bits.

Inlet manifolds. For a silvertop there are two types. The plastic one you have linked to and the alloy one from an escort as fitted to the engine in my vid. The alloy one sticks out of the bonet. Google tiger Avon, blue one. Westfield fitted the plastic one and routed the steering column and chassis brace around it. Google Westfield, there is a yellow one for sale with some great pics of the oem set up.

Yellow Avon.

And mine with a custom plenum

Is there a differance between the black top manifold and the silver top? A new black top manifold with all new parts, injectors etc is half the price of a second hand silver top manifold lol

Silvertop uses side fed injectors blacktop uses end fed injectors. Throttle position sensors are differant.

Both will work on your engine but use an ecu that relates to the sensors and not just the age of the engine.

So the black top manifold will work, is the genral layout the same as in throttle body position.

Which sensors would be required?

Crank and cam or are the silver top the same?
TPS is on the manifold.

I could hunt the scrappers for a black top Ztec wiring harness and ECU.


New OE Ford 2.0 16V ZETEC Inlet Manifold + injectors + fuel rail 1998 2005

Or would buying the following turn out to be a better cost effective route?

Ford Focus Ghia 2.0 l 4 door saloon

Get on eBay and buy a TIS CD. That will have all the wiring diagrams you need for old and new!

Crank and cam sensors cross over so you can use either on either engine.

The focus in general uses a 60 pin ecu the mondeo after 97 uses a 104 pin ecu in general for the zetec. There are exceptions to this as Ford was very much a parts bin special sort of place.

You would pick up loads of information by having a read through old posts on this forum.

Yeah I flick through and try to grasp what I can but there is a lot lol.

If I get an ECU without the corresponding key, does that leave the ECU useless?

Yes a pats ecu with no matching rdif chip is a paper weight.

lol what I thought. How can you tell if an ECU is PATS or not?

I spotted this has the keys etc

FORD MONDEO MK2 2.0 16V BLACK TOP ECU AND LOCK SET 1997 TO 2000/1 SHAPE

Yep if it's a 2.0 manual petrol it's a great buy. The postage would be £6~8 so you have a ready mapped ready to go ecu for £15.

How do I run it not using that key?

Would you go for that one?

If you use the Sierra steering column the Mondeo barrel and key are a ditect fit and the aerial goes over the top and holds with a spot of pu glue.

The other thing I was thinking was fixint the key inside the areial behing the dash. Then using a different style imobaliser and key etc?

So you want to bypass a free a thatcham approved Immobilizer to fit an aftermarket one at extra cost.

lol its not that, its the ignition key I dont need.
We use Thatchem transponders RIFD type and thats free.

Keep it simple for iva. Key for ignition and steering lock and immobiliser and its job done.

Yeah sounds fair. Guess will have to be a sierra or mondeo column then. Will have to see what ebay hands out lol

Hi!

Sorry for being a pain, being an engineer, like to ask lots of questions lol

If I bought this:

FORD MONDEO MK2 2.0 16V BLACK TOP ECU AND LOCK SET 1997 TO 2000/1 SHAPE

Would it fit this steering column?

FORD MONDEO MK3 ADJUSTABLE STEERING COLUMN WITH REMOTE KEY


Many Thanks!
