Car won't start
I'm hearing all sorts of hissing when it turns over and almost catches, but won't. Could it be fuel going through the rail? I can't
find any more vacuum leaks, but there are so many possible sources on this Nissan engine that I might not see one. I can't even reach a lot of
them.
PROBLEM: I have an inspection lined up for 10 AM this Thurs. It has to run. Is it going to be a waste of time to take it to any old garage to look at?
I am beyond it all at the moment, I'm afraid. I've cleaned the plugs checked the wires etc.
VERY rich when it used to catch, and plugs were fouled.
Long term going MS, just need it to go for one morning this week.

Easystart?
If you can get it started you will be able to find the leaks (or whatever it is).
Have you warmed the plugs in the oven, that can help a bit (I bet its not so warm over there at this time of year).
I don't see why a decent garage shouldn't be able to help. You need somewhere that fixes lots of old cars, they are the able ones.
Ideally Nissans and stuff!

Hadn't thought of warming the plugs. Yes it's minus 10 right now. The garage won't look at it unless it drives into the garage. They
have no idea how light the car is though. In fact they have no idea whatsoever, but I need them to get a plate!

I guess I meant take it to a local car guy. Someone with oil under their nails who can see your car with fresh eyes.
Its easy to get too close to a problem. I took my bike engine to a car place (they fix our normal cars) and borrowed their exhaust gas meter. They
had loads of good little hints that I hadn't thought of.
Just a thought.
I'm going to bed.

Dumb question, are all the spark plugs tight? When taking the snowmobiles out after long storage we squirt gas down the plug holes, then put them
back in finger tight, as we need to prime the engines three or four times to get fuel flowing. Once running we tighten the plugs properly.
Also check for a stuck valve.

Yup, I'd work on a process of elimination, take out a spark plug, attach it to a lead, hold the plug against the earthed engine body (with
insulated pliers preferably) and turn the engine over and see if you're getting sparks.
If you're getting sparks on all 4 try some Easi-start. If that doesn't work either the plugs are so rich they're not sparking when
under compression or there's something like a timing issue...

Silly suggestion, but are the plug leads on in the right order?

Easystart may get the engine going but doesn;t soleve the problem of why it won;t start!

Agreed, easystart does not have restorative properties. But it does help diagnose problems when first starting an engine. I wouldn't (and
didn't) propose always using easystart.
All he wants to do it get it idling. He isn't going to break it as those speeds. My thinking is that it is much easier to find a vacuum leak
when there is a stable vacuum (i.e. at fast idle) than when cranking. Also once its running and warm it is going to be easier to interpret what is
going on.

I don't know what Easystart is. We don't have it here.
My test has to be cancelled. I have one month or the government takes away my VIN. I don't know what to do.

Try squirting a little brake cleaner down the inlet when cranking , it works as well as easistart but isn't so harsh . Easistart is ether based
and very volatile

How will that help? I am confused.
I need a guy to come in, so I'm calling around the Nissan dealers to see if anybody will do house calls. I can't do it anymore.

You're really having a tough time with that car, aren't you... 
If you were in the UK the forum could have got a few lads together to sort you out - unfortunately you are just a bit too far away...
If I was in your position, with no-one to call on, I would probably approach a local garage with an enthusiastic mechanic - there's one in the
next village to mine. Yes - you'd have to pay him some money, but anyone with a reasonable knowledge of cars and their foibles can get an
engine started if it's not actually broken.
Isn't there such a place in your town - it would be GOOD to see that car of yours up and running!
good luck,
David

I called two Nissan dealers, and a garage local to me. The dealers can't see me til next week (I'll be at work), and the other guy
wouldn't have anything to do with it. Nobody knows what to do with a car like this. This is what I get for a turbo, and an engine with more
sensors than Carter has pills.
I know lots of guys over there would help in an instant, and I can't expect any help over the airwaves. It is just one of the more difficult
parts of this build, which I mistakenly thought was mostly finished. I really want this out of my garage and perhaps into the river - once it thaws of
course (in about late May).

Sometimes an engine just will not start even if it has fuel and sparks, a little squirt of brake cleaner into the inlet will often get an engine to
fire and run when it won't otherwise

I actually tried that. And the Nissan dealers won't touch it. I have an offer from a garage in Montreal to look, but it will cost me $1000 to
have it towed there, and do the job (minimum). They will also take my motor out, and put an MGB engine and transmission in, but not til March. I have
to think about towing it to Montreal for diagnosis, but the second is a given. I want this engine, it's myriad of wires, sensors and sh&te
gone.
The newer engine has two requirements: no ECU, and no turbo. That way, anybody who has ever seen a lawnmower engine can help out when necessary. Come
to think of it, when in high school, I couldn't get those to work either.
