[AZ58Cameo]

Hey Guys
Ive Got a 2003 Expedition

on, doesn't do it all the time just every once in awhile

I Had Fuel Pump Changed out Not to Long ago and had it into shop Because
of the stalls but they can't seem to find problem.

I Took it to ford Dealer they said it was a bad fuel pump, So I took it Back
to the shop that installed new one. They replaced the pump No Questions
asked and it still stalls on me

Can anyone Help Me or has anyone had same issue with there Expedition?
Thanks For any Help Allen

I can not say for sure what may be causing the problem. Many things can make a car stall. Ignition system fuel system the drivetrain. Even the computer could be causing the problem. Hopefully someone with more knowledge then me can help you out.

Does you have dashes in your odometer when it shuts off? Some of the early 03's had problems with the fuse panel (CJB) melting the PCM relay, which consequently shuts the car off.

I think there was also a thread about people having trouble with the fuel pump relay, also in the CJB. Not sure if a new CJB fixed the issue or not. I don't wanna tell you to just buy one since they aren't exactly cheap (+100 dollar part).
