No fuel pump prime
Ok so I was installing an aftermarket radio in my 87 iroc and after I wired it all up I turned the ignition on, stereo came on and worked but when I went to start it the car just cranks. When I turned it off and turned the key back on there is no fuel pump prime. I'm not sure what exactly could have happened but any advice is welcome.

Re: No fuel pump prime
I'll add that it had the factory bose system. I replace the fuel pump relay and still no prime. Is it possible that I fried the ECM? I'm stuck right now and this is my daily driver so any help is appreciated.

Re: No fuel pump prime
Check your ECM/ fuel pump fuse located by the battery check all the fuses while your at it. Good luck I'm with a no start/ no prime myself

Re: No fuel pump prime
I checked the fuse by the battery and it is good. Is there another ECM fuse on the fuse block in the car?

With the car OFF, using a voltmeter with long leads so you can see it in the cockpit, probe the green wire with a White stripe at the pump relay.
Now turn the key to the RUN position.
Did the voltmeter show voltage?
If no, the ECM is bad or has a bad connection.
