Question about Ford F-150

1 Answer

I have a 1991 ford F150 6 cylinder with dual tanks. I just changed the oil,oil filter,fuel filter,air filter,and master brake cylinder last week and the truck was running good(started every day since). started it up today and was filling up the tires and it cut off. tried to start it again and it would turn over but not start. when i turn the ignition on i can hear the fuel pump run and shut off a second later. do you have any idea what might be wrong or what to check?

Hi :) That is normal. When you first turn on the key the prime relay kicks in for the gas pump then shuts off. Once you start the engine the fuel pump is restarted buildes pressure as the engine needs it. When you shut the key off the pump shuts down.You could check the fuel pump relay which is different then the prime relay or check the spark module on the distributor housing. And the wire that go to all control module have a bad habbit of cracking and turning green with corrosion.

No brake pressure on my 1991 mazda mpv, changed master cylinder and bleeded the brakes.


you have to remove the pipes that go out of the master cylinder and purge the air later you connect the pipes and it purges the air in every auxiliary cylinder and the pedal will begin to have pressure

Spongy brakes


Does sound like you need a new master cylinder. On a 2000 you wont need to back bleed. You will just need to follow the instruction and bleed the master and all four points. you will probably need to bleed the ABS block and proportioning valve but only if they have bleeders on them.
