Turns over wont start


It sounds like there is no pressure in the fuel rail. The cause is the fuel pump is not working. I had one like that and the pump was running but not pumping. Check to see if the FP is putting out.
Good luck.

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)....


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.

During the summer time it will cut off sounds like it is loosing fuel pressure will turn over, but wont start back up until at least an hour later. Drives perfect during the winter time no problems,...


What causes this is ussually the oxygen sensor. It works when the engine heats up and if its no good, it will run your engine lean or even shut it down. check them and replace them. They should be done every 2 years.

Fuel pressure intermittently drops causing sputter and die.


check for 12v constant at your fuel pump if you are not getting that replace your relay.
if you are getting 12 volts at your fuel pump the fuel pump is possible to run tuel it gets warm then shut down to a lower rpm I would then replace the fuel pump

Could be the fuel pump. Try hitting the bottom of the fuel tank a few times while someone try's to start it, if it starts then the pump is on it's way out.

I have a 99 suburban that has 203,000 miles. It has developed a problem of taking a while to start. I have replaced fuel pump twice, the latest was about 3-4 years back. I have not checked pressures but...


I believe you have a fuel regulator weak or dirty injectors.
Try turning the key to the "on" position ( do not try and start) wait until fuel pump stops running (3-5 seconds or so ), turn the key off and immediatly repeat for 3 cycles. On the 4th key rotation, start the vehicle. Does it seem to start up faster?
If so, the regulator is weak, however, the fuel pump does have a check valve in it to prevent fuel from leaking back into the pump and maintain line pressure.
Try the diagnostic proceedure above first and we can go from there.
Good luck, let me know.
