New to the site but hoping for some positive feedback.

I have a 1995 3.4l camaro which I have dumped some major money into fixing. I just replaced the fuel pump and converted to dual exhaust. Replaced the plugs and wires upgrading to iridium plugs to try out. Fuel filter of course was changed during. Checled and have no codes to speak of. Turn the keyy no pump. Jumper the pump through the relay and have full pump power. Yet try to start it while jumpered and just crank crank crank.

Please tell me someone is able to offer some good advice other than the obvious check the spark and injectors. I get no power throught the green/white wire from the ecm. I guess my main question is if the crank positiion sensor is bad can it cut off all fuel flow as far as the pump and injectors only or am I looking at an ecm issue?

 

All aspects of fuel are cut off. Jumper gets the pump yes but no injector action. Carb cleaner and it fires up for the usual 5 second bursts of cleaner but otherwise I have nothing for fuel. My apologies forgot to add that

 

Not sure what that means ..... "to speak of".

Did you check the injector fuses?

Then engine should start with a faulty cam position sensor (DTC 17), or a faulty 24X crank position signal (DTC 36). But the 3X crank position failure prevents the engine from starting. But that would be a case where there is no spark present, and code DTC 82 would set.

 

Ran my hand held scanner. There are no codes present. Fuses are good. It's not making sence to me on why it won't give an ecm signal to the fuel pump relay as well as no pulses to the injectors

 

An update on my situation. Got the fuel pump relay to work. Turned out being a dirty connector for the cam position sensor. Go figure. Yet now my issue is my injectors aren't pulsing when checked with a noid light. Any suggestions would be greatly appreciated....
