The fuel pump in my EFI pickup wont pump the fuel from the gas tank through the fuel line into the engine so my truck wont start, it will turn over and run when I use starter fluid, so how can I get the fuel pump going?

Check for voltage at fuel pump, if no voltage check the wires from it back to the fuel pump relay for cracks or cuts, if that checks out change the relay. If the relay is good then the fuel pump is bad.

If you got the correct fuel pressure KOEO/KOER the computer might not be getting the Ne-G's signals to activate the injector/s

The MAF grounds the COR from there it goes to the fuel pump. Toy's has 4 different ways on fuel delivery.

1 system the computer controls the fuel pump speed like a throttle position sensor for fuel demand.
