Hi I have a camaro 85 fuel injection I have a problem mi car won't start I check the fuel pump relay and I have power on the orange cable but on the dark green/white wire is no power I traced all the way to the ECM and check for power and is no power going out so I check the fuel pump by pass it and work fine and I can turn on the car but ones I turn it off it won't star, when I run the car bypass it I have oil pressure and all works fine but no power coming out from the ecm I being searching and they told me it can be the ignition switch please help

 

There is a small transistor in the ECM that drives the fuel pump relay. It is common for them to pop. I use a 2N2907 or a PN2907 transistor to replace them.

Hi is that transistor located inside the ecm ? Where can I buy that part ? I check the fuel pump the relay is new and I put a switch to feed that dark green/white wire and it runs but I want to fix it the right way thank you for replaying me back

 

Electronics store for the transistor. The PN2907 is easier to get and is a plastic cased unit.

Arrow points to the one that usually fails. Note that GM also used a fully plastic one in that location. Such as the one to the right of it but taller.

Thank you for the help I'm gonna buy that and put it on and hope I fix my problem
