1999 Ford Explorer - Fuel Pump?
Here are the details:
1999 XLS with 134k miles. Starts with some hesitation and regularly 'lopes' when at idle. Have OBDII codes 0171 & 0174. I have replaced the MAF sensor, IAC valve, airfilter and plugs. I had it checked at Goodyear and they could not find a vaccum leak on the intake seals. They say it is probably the fuel pump. The pump has 65 psi when it is running, but when you turn it off it drops to 0 psi within 60 seconds. Does this diagnosis sound logical? Is there any other possibilities? I do not want to do the pump myself (I have done some and they are a pain), but I also do not want to drop $500 for them to do it. Any help would be appreciated.

I happened to be on vacation at the time. I had tried to diagnose the check engine light before leaving, but could not pin it down. As luck would have it it failed 500 miles from home. It would run for a short amount of time, until the pump heated up, and then it would quit. Since it was a Sat. night and I had to be back at work on Mon. I changed it in an Auto Zone parking lot at night using tools I borrowed from Auto Zone. Definitely not a lot of fun. I could not find any shops open that night so I decided to go ahead and do it myself. It would not be that bad of a job, if you had the proper tools and facilities.

It is a 99 XLS just like yours. If I remember correctly, there were two pumps that it could possibly be. Since I was in front of Auto Zone I removed the pump and matched it up. I cant remember the diffference now. If I saw the two side by side I could probably pick it out. Sorry I can't be of more help.

Hey, thanks for the help. I just looked at the estimate from Goodyear and saw a part number and it matches one at NAPA. It has to be the right pump, so I am heading down there now to get it. Thanks again!

I'd replace the fuel filter before the pump. I'd also replace the FP relay since it cheap and easy. Replacing the fuel pump would be the last thing I try. Good luck..
