Just bought a 2001 f150 reg cab long bed 2wd with v6/auto that has 119k a month ago now.
1- today I was at a red light and the oil pressure gauge went to NOTHING and the red oil light came on! I went to pull off the road and as soon as i touched the gas pedal the oil gauge went back to normal? I shut the truck off and checked the oil and its full. So I started the truck and went to the next job, it never lost the gauge again...any suggestions???

2- the shifter when you move it from Park always sets the over drive light on if i jiggle it it goes out then comes back on...when the lights on or off the od button still works because I watch the tach jump up and i feel the trans come out of od so it must be a wire issue. I removed the column cover and there are no broken wires at the plug so it must be the wires inside the shifter itself, can I pull these wires out somehow to check for a cut wire or broken wire?

3- my steering wheel is turned to the passenger side, it's like someone pulled the wheel off and clocked it wrong, but when I pulled the airbag it's correct because the cruise control wire plug is lined up correctly with the mount. I checked the steering shaft and there is a detent and that's correct. I didn't check the shaft at the steering box because I was told that also has a detent so what the heck is wrong that's making the wheel turned to the passenger side so bad?

4- this morning I left my house and I have a squeek that increases with speed. I believe it's a u- joint but I have no play when I checked the driveshaft? I installed all new brakes, rotors, calipers, rubber brake lines, front sway bar bushings and links, and all new shocks four weeks ago when I bought the truck by the way

 

1. If there are not other symptoms related to low oil pressure (noise from engine, etc), it's probably a bad pressure sending switch. Very common.

2. Chafed wiring harness that goes into the shift lever tube. Remove the column shrouds and repair.

3. Could be any number of things. Go through the whole linkage if you have to.

4. A mouse that likes to go fast? You'll need to be more specific.

 

I never said a mouse...i said a squeak as soon as the truck moves I can hear it. Faster I go the louder and faster it gets which is why I'm thinking u-joint. The driveshaft is tight which is throwing me off because evertime I've seen this the driveshaft would wobble on the u-joint when grabbed by your hand

 

U-joints can go bad without the excessive slop/wear. They can get dry which can produce the squeak at various speeds. Odds are that this is what is happening.
