SOURCE: my 98 mustang wants to start hard
what do you mean start hard?
you mean slow cranking or long cranking before start?
SOURCE: 1991 Explorer fuel pump
so where is the shut off reset for the fuel pump on the 91 explorer? does anyone really know?
SOURCE: 2002 windstar fuel delivery?
if the pump is not working it may be the fuel shut off, look in owners manual for location.
SOURCE: 98 chevy suburban engine turns over but wont start.
did you do a fuel pressure test? or did you just push in on the valve on the fuel rail and gas came out? if thats all you did, that will not tell you anything.you GOT to do a pressure test. just 3 to 5 pounds under and it will not run. fuel injection is fussey. you can rent a pressure gage at most major parts stores. they can even tell you what the pressure shoud be. just because you can hear the pump run, dosent mean its pumping, or at least the right pressure. did you also chk.for spark? need to do that to. still need air, fuel, and fire to make them run. good luck.
SOURCE: do you adjust the tps sensor on a 94 ford f250 5.8l when replaced
Best thing to do with a vehicle that you don't have any idea where the timing is supposed to be is something I discovered when I was a mobile mechanic. Loosen the distributor a little. Block the front tires and maybe even place the front bumper against something solid like a building. Put the truck in drive and hold the brakes down.Preferably have someone else do it while you are under the hood. slowly start raing engine speed. When it starts to stumble, move the distributor just a little one way or the other till it runs better. Once it does clears up, put a little more throttle to it. See if it keeps up. It may get to a point your back wheels will want to burn rubber. Once it does, let of the gas fast. If it dies, you have problems. Then you'll do what I said in the beginning and take it to your dealer to plug into it. Dealer, parts house, whatever. If it stay running good. You may have found the timing point. Good luck. If this is helpful, please post as such. If it is a fixya....you know.TY
