I have a similar problem to those discussed above. F-150 300 straight. Runs And starts good in cold weather. Starts in hot but when I run it and shut it down wait, its hard to start.

Asked by Mar 11, 2017 at 06:07 PM about the 1996 Ford F-150

Question type: Maintenance & Repair

If I wait till it cools down then it starts and runs good until I shut it down and
wait a few minutes.  Then it becomes hard to start.  I paid mechanics over 700
bucks to solve the problem, but still have the problem.  If I get it started, when
its hot, it runs really rough for 1-=30 seconds and then begins to run correctly.  
It has never stalled when driving, just after it sits.  Like I said, in the winter time
I have no problem, it just when the air temps get over  70 or so and then the
problem returns.  Has anyone ever figured out for sure what the fix is?  Thanks
for any help.

Was the igniter/pickup/stater replaced in distributor, Not sure if this is it or not but I had a issue with mine stalling out after 15-30 minutes then would not crank back up for 30-45 minutes. Ended up being the pick up igniter module, located in the distributor. May check it out if haven't already.

Possible fuel pump comes to mind(only because if not gone out fully may act up first). Crankshaft Position/Angle Sensor, Camshaft Position Sensor. Also if you can be ready to check if you have spark or not and if you have fuel or not when it does not start would be helpful in diagnosing the issue. May check fuel regulator.

I have had most of all those things check out and or replaced. It starts good when its cold outside or when its hot and the engine has cooled down, and once you get it started it runs good. It most times will start, but it runs really rough and then finally kicks in. It does act as if its staving for fuel, but I had both fuel pumps changed on it. And like I said, it only acts up on days when the temperature out side get up to or above 75 degree or so. Thanks so much for taking the time to try help me on this truck. I had a 1987 F150 that I had 250,000 miles on and it ran like a trooper. It was all rusted out, but engine wise not problem at all. So I bought this truck used with about 30,000 miles on it. I now have about 130,000. It never did this until about 4 or 5 years ago and the mechanics have tried all they know but after hundreds upon hundreds of dollars, they haven't helped it a bit. I think there's got to be someone out there that can hit the nail on the head, as this can't be the first ford to ever have this problems. Again thanks to all of you for your time and information.

I do have spark and do have fuel. I have had those checked.
