Question about 2001 Ford Explorer Sport Trac

1 Answer

2001 explorer sport , fuel pump? vacuum leak? 619 scan tool data provided, any suggestions/solutions

The problem is I can jump in and it will start first try, fuel pump is heard activating, idle is rough, feels like truck is about to die, pumping on the gas usually causes it to catch and smooth out......after 10 minutes or sometimes less than that truck starts to sputter, step on throttle it dies faster, sometimes when stepping on throttle before it dies helps and truck is able to rev up and then back to idle and not die. But most times stepping on gas when it begins to sputter after running for 10 minutes or so causes it to die once it dies it doesn't start back up and when key is turned on and off, no fuel pump activation noise. I am at a loss for solutions based on the fact that the next day when I attempt to start the truck, cycle key on and fuel pump is heard.............and then the same routine all over again with the sputtering, and sometimes catching, sometimes not and dying out on me immediately when feathering throttle, and then not start again, and no fuel pump noise is heard from several cycles of the key. But if I let it sit and come back the next day, same routine, starts, fuel pump is heard, bogs, feather throttle, sometimes runs/dies immediately, if it runs its never for more than 10 minutes or so, then bogs and dies, and key is cycled and no fuel pump noise, truck doesn't start until the following day......its like magic!

The fuel pump is suspect but I believe there's also a fuel filter inline on the underside of the drivers side chassis. Fuel works off pressure so if the filter is clogged, the pressure remains between the fuel tank and the filter. Once the fuel has siphoned off between the filter and injectors, it dies but because there's positive pressure at the fuel pump, it won't come on until the pressure slowly seeps past the clog after hours. It's worth a look!

Water pump have anything to do with the fuel pump. Car will start run for a few sec then die. If you give it the gas it will stay running let off it dies. It a 98 regal supper charge


No. They are separate. If the idle is too slow try adjusting the idle screw if it is available on that older vehicle. Many things can cause a rough start / idle and an experienced mech will need to look at it. Good Luck.

New fuel pump and fuel lines.. Ran like a champ for day... BUT


Are you saying you think it is getting too much fuel, or not enough ?
Could be the choke or something inside the carb.

High idle and rough idle.


Sounds like a serious vacuum leak to me. Can you hear any air rushing under the hood when it's idling? Wiggle all your hoses around while its running and listen for a hiss. If it was a sensor his scanner should have picked it up, and if the fuel pump was no good, it wouldn't run at all. Aim a timing light at the crank mark. If it's jumping back and forth, your timing chain has jumped.

89 suburban. No spray from injectors after replacing ESC


The fuel pump should be in the 20s. Also it could be losing presure slowly. Leave the fuel pump pressure gage on for at least 2 to 3 hours to see if it is losing pressure - It's a start

Engine will start and rough idle but dies when either the brakes are applied or the lights are turned on!


have you checked out your fuel filter? I had my 2003 denali do the same type of problem and it turned out to be a very dirty fuel filter.
