1990 SOHC 2.0:

I have no power going to the fuel pump. I can only find an MPI fusible link under the hood which is fine.
Can someone please guide me as to where to find the fuel pump relay, fuse, or any wiring that I can check? I do not have the FSM only the Haynes which is not very helpful.
Thank you for your time!

I am also trying to find the relay and also have the Haynes, which is useless. Any insight/clues/answers other might have will really help.
TIA.

The relay is right under the glove box.

i can pretty much garantee it is NOT the relay.
chances are its a failed capacitor on the ECMs circuit board not turning the relay on.

that if your 100 percent sure that the pump is not recieving a power and ground signal during cranking. (the car MUST be cranking to activate the pump)

Right, it's the C108 capacitor in the ECU. It probably smells like old fish under the glove box. The capacitor has leaked and the PCB is probably messed up. So, take of the capacitor, clean the PCB and change the capacitor. 100uF/16V or higher voltage and the max temperature should be 105C.
