SO i just recently put an 04 motor in my 03 Z everything works fine all gauges and etc. I get no check engine light or anything but the fuel pump is not turning on and the engine is getting no fuel so it wont start and ideas how to test the pump reset or etc. IF the ECU is different would that effect the pump not turning on. HELP !!!!

 

There should be nothing different at all .....it probaly has just blown the fuse for the pump.the ecu should be the same as long as it was before the 2004.5 cutoff and i think that only is for the trans.

 

sounds like a fuse the only way to test the pump is to pull it out of the tank and apply 12v to it see if it spins.

 

it should of thought of that lol it was the fuse!

 

Hey i did the same stupid thing this week when my car wouldnt start after i shorted a wire.
