This is on my 97 F150 xlt 4x4 w/4.6V8 automatic. Truck has 115k miles.
So sunday I was driving on the high way going about 50-65 mph. All of a sutton the rpms dropped like the car was going to shut off. Check engine light flickered for a second and the car cought itself.
It did it like 2 times and then didn't do it again. Drove fine the rest of the day.
Next morning drove it to work. No issues drove like it always has. On the way home though it did it 3 times in a row and then finally just shut the truck off. I had to coast into the EM lane. Tried to start it but no such luck. Just cranks but doesnt start and run. Had to have it towed home.
Got home and the tow driver got in the truck put the key in and it strated up. He was like hmmmm, and me too.
So am I looking at the fuel pump going bad or is bad already?
Or something else?
The truck started up fine all days, idled fine too. Does now too.
No check engine light is on now, and everytime it acted up the light would come on for a split second then
go right back off.
Spark plugs are all new and motorcraft. Only one needs to be replaced on the passenger side back. It's a
pitta to get to. Dont think a bad plug would cause my issues though. Also has a new fuel filter.
Anything else that would cause my symptoms?
I was thinking maybe fuel pressure regulator, but the truck should still run, just not good correct.
If that was it, it would run rouph all the time not just all of sutton.
Whats the easiest way to change the pump. ( have a full tank of gas right now 24g)
