Yep, I am the new guy. Cannot find any threads to match my exact symptoms. Here is my problem. 91 f150, drive it 5 out of 7 days a week. Recently had to park it for approximately 2.5 weeks due to an illness. Went to crank it and let it run for a few minutes, then it just cut off. Tried multiple times, cranks every time but will soon cut off. Tried driving it, put in gear and within feet of moving..cut off. Idles fine. Half a tank of gas. Doesn't exactly sound starved of gas before it cuts off, actually when it cuts off its kind of sudden with no warning, just off. When it sat, sat on incline with tailgate end downhill. Any theories? Suggestions?

 

When was the fuel filter last changed?
Does it restart easily, what do you do to get it to restart?
Has any maintenance been done to it recently, if so what?

If the coil is original, the original coils gave all kinds of problems.

 

It starts easily, like it always had. Fires right up. No recent maintenance done, fuel filters haven't been changed in long time. I believe I have 2 inline and one in the tank.

 

An engine can idle fine with little fuel and quit altogether when demand rises because not enough can get past a restricted filter.

 

Thanks, that is where I will start.
