    Replaced Fuel Pump - Immediate whining noise from Tank and hesitation

    I did not replace the fuel filter prior to replacing the fuel pump. I probably should have tried that first. It could have saved me an hour of work... I picked up another Delphi pump, AA just swapped it out at the store with the same model. It was a fun project and the weather was good.

    Replaced Fuel Pump - Immediate whining noise from Tank and hesitation

    I replaced the fuel filter 12-18 months ago. I use my Expedition for hunting and snowy driving, I probably put on 4-5000 miles a year. I'd be shocked if the fuel filter is clogged after 8-10k miles. I could be wrong. I started noticing start up issues 1 or 2 times a week. Wouldn't start on...

    2002 Expedition Power Door Lock not unlocking when pressing U

    Hello All This morning I tried the incorrect code on my Expo key pad multiple times. I guess old age/concussions have caught up to me... After a few minutes I remembered the correct code and was able to unlock doors. Now my power door locks will not unlock when pressing U on driver/passenger...

    1999 Expy AWD Vibration on medium/hard acceleration

    I got under my expy and I was able to twist the front drive shaft back and fourth. Forgive me for my ignorance, should it be able to rotate clockwise/counter clockwise with Expy not started? I shook it at the front U joint, no wobble or play in u joint. The rear drive shaft was rock solid, no...

    1999 Expy AWD Vibration on medium/hard acceleration

    Hello All Sorry for the delay in replying back. I pulled the 4wd Fuse, and the vibration has gone away. So i am guessing it has something to do with that. Where do i go from here? Do you have any recommendations on where to start looking? Thanks so much

    1999 Expy AWD Vibration on medium/hard acceleration

    I'm not getting a CEL. I failed to mention that I have a rough idle at stop lights.. I will check the hoses to see if I have a vacuum leak. I will also check to see if i have a bad ignition coil or boots. I had the plugs replaced 6k miles ago. I really appreciate your input, will keep you...

    1999 Expy AWD Vibration on medium/hard acceleration

    It doesn't seem to me like its the suspension. Yes I can feel the vibration through the pedal on acceleration. I will pull the 4wd fuse tomorrow morning and check for the vibration. If that fixes the problem should I focus on the drive shaft?

    I started to notice vibration coming from the front of my expy between 30-40 mph or when the engine is under load going up medium inclines. The harder I accelerate the more pronounced the vibration feels. When I accelerate slowly I don't feel anything. Once i get up to speed on the highway it...
