I have fitted a rover 2l turbo engine in my Fisher Fury using an adapter plate to a type 9 gear box. The water pump is now electic to replace the original pump and power steering pump.
All has gone well I have slimmed down the wiring loom and the engine starts but cuts out after 1/2 seconds.
I have run the engine by feeding petrol into the pleniem camber . This allows the engine to run. This tells me that the ignition is OK .
My thinking now is that the ECU is cutting the fuel off. The ECU has a wire coming from pin A3 for the alarm. I have the original ignition switch and key plus remote .
Can anyone tell me how to connect this up. The engine came from a1995 rover 800.
Help please

A work around is to run a switched live direct to the pump and see if it runs OK with that in place. I suspect the ecu is switching off more than the pump if its security features are active still.

Only the earlier 800 all that was easy to by pass by connecting the fuel pump relay to the ignition howeverat 95 your donor must have been series 2. The security system on the 800 series 2 is a mishmash of Japanese and Uk bits and it changed a couple of times. Your car will have a Mems 1.9 ECU I am told the mod required to the engine ecu is quite simple (cutting the connection to a pin off) BUT it can only be done if the system is already disarmed when the connection is cut.

So you will have send the ECU to a specialist to get the imobiliser function disabled. Avon Diagnostics are experts in this kind of stuff but no longer deal directly with the public. Talon Sports car could be of help but their web site is currently blacklisted by Google and a lot of AV software for being virus infected.

you can send the ecu off to best of british they can then removed the immobilizer code BUT there is a pin on the ecu harness from memory it pin 20 ish that needs to be disconnected so the ecu doesnt accidently try to recode itself.

Have you still got the 3AS or 5AS immobiliser box wired in still?

If you have and you don't disconnect the pin on the ecu the ecu will try to obtain the code from the 5AS box and try and recode the system...... which is all well and good if it does it as it should but it is a very hit and miss system that doesn't always work.


Hope this helps

The series 2 Rover 800 the security alarm function was contained in the CCU, they didn't use the 5AS, however it functioned the same as far the MEMS ECU immobilisation.
