fuel pump doesnt prime,
so ive changed the fuel pump,relay,fuses, computer and ive checked for any disconnected lines.
Theres power in all the lines I had a member test with a multimeter.
If I run a 12v to the pump direct it sends fuel thru the rails but its as if the injectors arent on even tho they have power
Not sure what else I can do

Also check out this diagram. Seems from the PCM power relay the power goes to the fuel pump relay and then to all the other shit its connected to.
Have you checked your PCM power relay? Seems to me if your injectors aren't getting power and your fuel pump isnt priming then it very well might be the PCM power relay or one of the connections to it. Keep us posted

I found out if the inertia switch is unplugged the fuel pump has 10.2volts but if its plugged up it has no power at all and the switch works fine ive checked it with a known working one

weird...not sure what would cause this...have you rewired something back there? is it possible to have the inertia switch in backwards? I don't understand how the fuel pump can get any power without the switch in place...

and also do the injectors get power when you pull the inertia switch? or are they still powerless?
