Fuel pump not getting power, relay not getting power

Hello,

I have included wiring diagrams for your vehicle's fuel pump circuit, the fuel pump and the fuel pump relay. Please go through this wiring diagram and look at the fuel pump relay and let me know if you are not getting battery voltage at pin #1 or #3 or either of them. We can go from there.

Thanks,

Hello again,

Okay, a relay is broken down into two separate sides, the control side and the power side. The control side has a switched power source coming into pin #3 (brown wire) which energizes the electromagnetic coil. When the electromagnetic coil gets energized it pulls the switch from the power side closed which has electricity coming into pin #1 from a "hot at all times" fuse and allows the electricity to continue on to the fuel pump from the now closed switch. As soon as the switched power going into pin #3 is switched off, the electromagetic coil deenergizes, and the switch on the power side opens, breaking the circuit and electricity that comes into pin #1 is interrupted. So let's check the Injector fuse(15A) in the fuse box on the left side of the engine compartment and get back to us with what you are able to find out.

Thanks,

If I can jump in here. Can we test for spark? if the computer does not see the engine turning over it will not turn the fuel pump relay on. Here is a guide:
