Replace the fuel pump relay. If that does not solve your problem the fuel pump needs replacing. On a 14 year old vehicle if the fuel pump has never been replaced it is not a surprise it is going bad.

2007 gmc yukon will crank but not start. then i crank it again then it starts. this been going on for a while. what would be the problem to this and what is the solution to this problem. thanks.


albert tuisa, There are many things that could cause this problem but the first thing that comes to mind is you have a clogged fuel filter. When you first turn your key to start your vehicle a prime signal is sent to your fuel pump. What happens here is the fuel pump is activated for a second or two to build up the proper fuel pressure for the engine. If your fuel filter is clogged a little, this will keep the fuel rail from getting the proper pressure it needs and a second or even a third prime signal is needed to start your vehicle. Replace the fuel filter. Good luck with this.

Ford F250 turbo diesel cut out and died as left house this morning, cold morning. Will not start, not even a cough. Have new fuel filters, need location of the filters, anything else I should check?


if you have the 6.0 then the filters are located on top on the motor right beside your oil filter and under the drivers side on the fuel pump, check to see if you have diesel in your bowl where the fuel filter is, no diesel in there your fuel pump might be dead, check fuses to fuel pump and check relay on the passengers side kicker panel, check your owners manual

Engine wont start without priming with gas first, then runs well


i have the same problem on a 98 jimmy 4.3 4x4.
i replaced the fule pump and have good pressure.
new wiers & coil (good spark) no MIL & no codes.
will only start when primed. it will run & drive all day
with no problems.
but once it has been turned off (warm or cold) i will
have to prime it once again to start it.
i have another engine that was in it before it spun a bearing.
it ran fine so i know all parts are good.
i swaped the mass air flow and throttle body but i still have
to prime it everytime to start it. am i forgetting something?
should i swap out the intake with the injectors?
any help would be sweet. thanks.

Wont start when the temp warms up, until I hear the fuelpump buzz


youve either got a weak fuel pump,or bad pressure regulator,or clogged fuel filter change it first!!!
