325e Injector/Fuel Problem

[logicalx]

I just picked up another 325e that has low mileage but it has been parked for quite a few years. I have flushed the tank and filled with fresh gasoline, changed fuel pump, fuel filter, and relays. The car will start but only run for a second or two. Once it has been started three or four times It will not start again until it sits for a few minutes. I unplugged the cold start injector and it will not start at all. So it seems that it is only getting fuel from the cold start injector. I've tried quite a few ideas so far but nothing has shown any results. I would really appreciate any help that I can get.

could be the pintles rusted on the injectors, check that they are firing (noid light)

If I can find my volt meter I'm going to try testing to see what kind of signal I am getting to them. I also noticed that the car has some sort of alarm but I am not sure if it would effect anything about the car starting.

if they cut any wires it could effect it

Hi, from Chile, new on the forum, new on Bmw´s, got a 83 323ia
had exactly the same problem (the car will start but only run for a second or two. Once it has been started three or four times It will not start again until it sits for a few minutes), can´t find solution. Any findings?
Appreciate your help

you can't see an injector pulse on a volt-meter, they pulse too fast.

check the injector harness connections (under the intake mani)

Does older than 88´s have a harness conector for injectors? Not looking at the car right now. If no conector, where else to look?

[chileelky]

Fuel presure ok, FPR, filter, changed, all fuses revised, looks injectors not working.
Mine (83 323ia) has not injector harness conector.
Tomorrow I´ll change injection relay
Any other places to look for?
Thank you

Injection relay changed, car´s running smooth now.
2 questions:
is there a code for that failure?
how much is that relay in USA?
Thanks

Relay is like 5$ or free from the junkyard. There won't be a code I don't think.
