I'm in the middle of a wire tuck.. ( i know, famous last words LOL) But i'm pretty sure everything is back together correctly but I can't get the pump to prime.. I checked for voltage to the ECU.. got that.. I checked for voltage coming from the ECU to the fuel pump relay.. got that.. is there anything else that could maybe left out to get it to prime? TIA

found the problem! bad ground

 

I get 12V at the fuse for the fuel pump that is in the fuse compartment in the engine. I tried to test the connection at the fuel pump itself in the trunk and I only get 5V. There are two connectors on the fuel pump. One is a 4 wire and the other is a 3 wire. The three wire one is where i can get 5V off of the yellow wire with a stripe and either of the other 2 wires.
I looked below the engine fuse box and see a green/yellow wire connector. Is this what you are calling fuel pump test connector? If I unhook this and apply 12V fused I should get the pump to run if it is still good

 

Your 5 volts is coming from the fuel level sender circuit (3 wire connector).

 

hey im having the same prob with my fuel pump ..... where was your bad ground ?
