Locate the fuse box/relay panel I believe the fords had them in the engine compartment, it soulds like your fuel pump relay is stuck in the on position just pull it out and see if the pump stops.

My 1990 4runner i turn it over and starts fine and then runns out of gas if i turn it over and keep it turning over after it starts it will keep running


I would check the coil to see if the power side is getting battery voltage with the key in the on position. It could be the key switch.

Electricity is not reaching fuel pump. Wiring is fine. 1990 F350 4.9 Emgine Automatic transmission


the power relay activates the PCM, engine computer. The PCM activates the fuel pump relay that turns on the fuel pump with key ON. It runs for 5 seconds, then it shuts off, unless the engine starts. Can you hear the pump run (hum) in th fuel tank when key is turned ON?

Also, reset the inertia switch in case it tripped. Owner's manual will tell you where it is. Rest is pressing the buton.

I own a 1990 Jeep Cherokee Pioneer and for some reason it will not start. The fuel pump AND fuel filter are brand new but when you turn the car over it wont start. It tries to start the longer turn the key...


you have a fuel pump relay . Check to see if the fuel pump is humming when you turn key. check for proper ground for fuel pump. try spraying some carb cleaner into the intake then attempt a start. The engine will run for a few seconds, this will verify spark. corosion at the electrical connections is always a possibility. and lastly can you get the engine running by opening the throttle when starting?

I dropped the fuel tank to drain old gas.I put new gas in and turned engine to start it didnt start. Should I be able to hear fuel pump if it is working?This is for a 1990 ford e-150 van.Also where the is...


Turn the key to the ON position without starting the engine. You should hear the fuel pump running for 5 seconds if working. This primes the gas to the injectors when doing this. If not heard running check the oil pressure switch for the 12 volts needed to run the fuel pump starts there on that harness. When the engine starts and the oil pressure reaches the normal pressure the computer shuts off that circuit and turns on the fuel pump relay to run the pump. The relay stays on till you shut the engine off

Toy starts runs 10 seconds and stops change fuel filter now wont


When you tur the key forward do you hear the fuel pump running? You should hear a low hum for about 20 seconds near the gas tank and then it stops. If you hear this your pump is good. If it keeps running or you can't hear it at all it's bad or the main fuel pump fuse is blown.

sounds like your fuel pump is going out. One thought might be that the fuel filter is causing enough resistance to over heat the pump. I would check the fule pressure to determine a free flow of fuel.

1990 ford tuarus will crank over but will not run. has fire to plugs, but no fuel to injectors


Check to see that fuel pump is working. The pump is located in the fuel tank. If you turn the key to the on position you should hear it running. Check the fuel pump relay for correct operation also.

Fuel pump keeps running


My 90 Ranger did that when I put in a cheap relay. It's under the fuse block under the hood.
