Hi guys, I hope you will be able to help me or point in the right direction.
Where do I start... I bought a 1984 944 at the end of August this year as a non starter. It was said that this must be something to do with the immobiliser - luckly enough that was the issue - the fuse on the immo box was gone. As soon as I have replaced it the car started! That was great ... I thought. So I decided to take the car for the MOT (as it the old one run out before I got it) to see what needs to be done. On the way to MOT station I have noticed a big fuel leak... it turned out that the fuel pipes close the the back of the car have cordoded. I have cut them out and replaced the rusty bits with rubber fuel lines. Took the car for the MOT. It needed welding and some other bits and bobs like tie rod ends etc. During the test it just died at wouldnt start at all. I have figured out that the connectors for the cranks and engine speed sensor were loose - that was fixed and the car started again. But then every time I tried to start it when cold it was just getting worse.
Situation now: Car wont start when cold unless you use easy start. Then after a few times it will eventually go and when warmed up will run fine.
What I have done: Replaced ignition leads, rotor arm and distributor cap. Replaced spark plugs (although as I have found out the ones in the car were fairly new).
I want to replace the fuel filter tomorrow to see if it kicks in but I doubt it. I have checked all of the old posts on the forum but I still dont know which way to go and what to check.
It looks like the car is not getting enough fuel as it does not start unless you spray in easy start... I have seen some posts about the pressure regulator - where exatly is that located? Between fuel pump and the filter?
I have seen posts about too low voltage on the injectors - what should it be? 12V - and good ground? How can I check ground? Can I just wire it to the battery temporarly to see if it helps? With the fuel pump relay - I have taken off the plastic cover and tried to run it constantly by manualy enabling it (pressed two bits by fingers and it runs) but the car still wont start. Some say that bad ground could cause that - bad ground to the ECU - the question is - where is the ecu exactly located on 944?
I have also red about the cold air sensor - if unplugged the car should start fine when cold - but it doesnt.
Another article on clarksgarage and on wilk website tells to test the airflow meter but I havent done it yet.
I would apprecieate any ideas and advice on where should I start. The car has been sitting in my mates garage for the last month and I need to remove it tomorrow. Its the last day I can do something in a friendly (not freezing/wet) environment.
Looking foreard to get some responses.
Cheers!
