    The fuel pump runs, whether the key is turned on or not. We had the ignition switch off of the steering column, on the floor, key on the kithcen table. Pulled the relay apart, still ran. Pulled the fuse located next to the relay, that stopped it, but cannot leave fuse out.....

Sounds like you haven't got the right relay or the replacement has failed. pull one relay at a time and go back to the rear of the vehicle and listen for the pump. make sure the key is on when you do the test.

Put new fuel pump relay switch checked fuses but the pump still doent come one


The sock filter on the bottom of the pump is bad and it burned up the pump. You will need to drop the gas tank and replace the pump.

Where is my eec computer located on my 1991 f150 300 straight 6 my fuel pump wont shut off with keys in my pocket. i already replace the ignition switch and fuel pump rely. any suggetions on what it could...


It is in the front seating area, driver side, behind dash, upper corner, mounted on dash with support brackets. I don't think the computer would fix your problem. Does the fuel pump quit running when you remove the relay? It sounds more like a wiring problem, like a wire that should be getting ignition battery, (going to the fuel pump), is getting constant battery. I would check the wiring for the fuel pump relay.

1991 no start.but have fuel and fire..


Your ignition switch is good if you are getting spark to the plugs. You need to find out why your not getting fuel through the injecters.Check your relays again . Do not crank engine over ,but turn key on and off 10 times to charge the fuel lines.But I think you need to check your wireing and get your instrument cluster working first.

Will not start, does turnover, but seems to be getting no gas. will turn over if i spray auto start in the carborator.


check fuel filter to see if its clogged. (cheapest easiest)
if that doesnt work rebuild carburetor (expensive but fairly simple)
if that doesnt work pull tank if it is low on gas or pull bed if gas tank is full a replace fuel pump (time consuming, hard to do, but fairly inexpensive) I had this problem on a silverado I had and it was the fuel pump.

No fuel


Be sure you have checked the impact safety switch. Your owner's manuual should tell you where it is if it has one. This switch kills the power to the fuel pump after impact. It has a push button reset. Check for voltage at fuel pump to rule out having to change the pump again.

1991 chey pick up 1500 electric fuel pump


Hello, Only 2 wires show be hot when fuel pump power is supplied. I think that the gray wire is the power side so ck that wire to ground. Also, fuel pump power is supplied from your oil pressure switch and the fuel pump relay only supplies power for a few seconds until the truck is started. Keep in mind that the fuel pump will only run a few seconds by just turning the switch on. If you want the pump to stay on without the motor running , you will have to by-pass the fuel pump relay.
I hope this will help.
