    325e Injector/Fuel Problem

    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.

            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?

                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.
