    Did you check for power on both side of the inertia switch? 
    How did you check for power at the pump?

Okay I've had my Ford Truck for coming up on 18 years, and well it's been great truck... That being said I will say troubleshooting a Ford with all the issues around the electronics, relays and ect. can be a real pain... Make trip to junk yard and get few things.. 1st try swapping out fuel tank selector switch, then fuel pump relay... switch is in cab and relay is in engine compartment on drivers side... if neither does it i bet you anything its the computer itself.. mine was acting up it was doing same thing for awhile.. when that computer starts acting up the problems can vary and all together change... makes troubleshooting next to impossible good luck.

I have a 1990 mustang lx 5.0 and i've been recently having problems trying to start my car,?

Click and no crank you need to go to the battery and ensure they are connected well,If the car just click check the battery terminal and do you have a clean connection remove any grime on it,Get the car to crank and if you do get it to crank and you still dont hear the fuel pump I want you to direct the fuel pump through the OBD 1 connection.I also would like you to gather a code by counting the flashing light,Do you have this connection it on the right side front3_31_2012_6_14_26_am.jpg

No power to fuel pump on a 1993 ford probe. all fuses are god,fuel pump relay is good and fuel cut of switch is good as well but still no power to pump?

If you actually have no power to the pump and all the fuses and relays are good check the wires for a short and if that is good replace the ignition switch. If you think the condition is no power to the pump because it doesn't seem to power up remove the pump and apply direct power to it to see if the pump is the problem.

I don't here the fuel pump ever kick on in my 1990 Ford F150, and I tested all of the fuses and they are good. I was thinking the relay for the fuel pump might be bad -- any suggestions?

It's under your hood, in one of those boxes, and should be marked. Your pump won't cut in if it's fried either. Check to see if there is power at the pump. Maybe you just have a loose wire. You can always hope!

Check fuel pump fuse, remember fuse send power to relay and relay sends power to pump, Check power wires to pump and make sure FUEL PUMP FUSE IS GOOD if not replace and take care of this problem. Good luck and thanks for using FIX YA.

Then the engine fuse may be blown it will be marked ECM I think, the fuel pump and injector circuits are two seperate systems, the fuel pump most likely has a stuck relay.
