Question about 1991 Ford Mustang
The firing order is shown below from Jeff back in April 2011.
The order is 1-3-7-2-6-5-4-8 and cylinder one is front passenger side of engine.
I would agree with the person who answered your question earlier, all of the injectors are powered by the same red wire, half of them are grounded on one circuit and the other half on a second circuit. Both circuits come from the computer.
So if you have spark the ignition module is working, which would point to the computer being the problem.

The crankshaft sensor went bad. I Was'nt getting any fire from the coil pack. Tried switching coils and still nothing, tried switching ignition modual, nothing. I checked to make sure it was in time and it was. Nothing left to check so I changed the crank sensor and it firerd right up! Thanks.

SOURCE: I have a 1991 ford
Fuel pump relay is under the hood, passenger side, front side of strut tower, mounted on the fenderwell. You should have a safety fuel shut off and If I remember right Ford likes to put them under the dash on the passenger side on the kick panel

I'm showing it on the passenger side of the radiator support, in the CCRM, Contstant Cntrol Relay Module. 4 realys in one module. For 1994 anyway. I don't have 91.
