My '86 F150 with the fuel injected 302 and 4 speed, started cutting out on me last night. It was running great until I got off the interstate and when I tried to pull up to the stop sign after the car in front of me pulled off it died. It took several tries to get it restarted. The only way to keep it running was to get my foot on the accelerator. I was able to drive it on to the house, but it was running really slugish. When I got it in the driveway it would idle fine like nothing was wrong with it.

I let it sit for about an hour and went out there and it fired right up. I let it run for a few minutes and even tached it up some and it sound good and ran good from idle to about 3000 rpm's. I tried to drive it around the block and by the time I got to the end of the road it was running sluggish again. I drove it back to the house and let it idle some more, it wasn't idling very well, but it was running smoothly. It was almost like it was flooding it self out or didn't have a suffient fuel supply or had some restriction to the exhaust. It was dark so I couldn't really check it.

Anybody got any ideas? Every had this problem before?

My initial thinking is a fuel problem. Possibly the high pressure fuel pump cutting out?

I just tuned it up a couple of weeks ago. I just replaced the fuel filters last weekend. I have burnt several tanks of gas out of it since the tune up, and at least one tank since I replaced the fuel filters and it has been running better than ever. I just filled it up Sunday night and have driven it about 60 miles since then, so it has plenty of fuel in the tank. It is good fuel from Chevron.

Any help or ideas is appreciated.

 

I am thinking now it could be the converter getting stopped up. What do you'll think?

Anybody got any ideas?

 

Could be a fuel filter? They are cheap and easy to replace. Just do it if it hasn't been done in at least the last year or 2. Good luck!

I just replaced the fuel filter. Oh well, I will figure it out eventually I guess.
