2001 F150 won't start cold

Been having issues lately where if it's cold in the middle of the day the truck just cranks but won't start. Couple times i was able to start it after i sat a bit and tried again but that time it started right up and died instantly. So i started giving it gas the second it started. This time it was a lot colder and it didn't even start the first time. This isn't early in the morning this is like noon.

I read on a couple other forums that it could be the fuel control unit but wanted to find other opinions. This page shows where it's located but this is an '06 not '01 so might not have one. Somewhere i have a shop manual but have to figure out where it is, haven't looked at it since before we moved.

I'll add this for a just in case one day someone has the issue it shows a good picture of a crack in one.

Re: 2001 F150 won't start cold

Try your coolant temp sensor for the computer not the gauge. That's a likely suspect.

Re: 2001 F150 won't start cold

and where is that located? Near where the thermostat is and how do i know what goes to puter and what goes to gauge? I am lost when it comes to these new rigs. Now too, if i take a blow dryer or heat gun and warm up this thing some would it start if this is the problem or is it dependent on the water temp and make no difference externally?

Re: 2001 F150 won't start cold

I found it, it's under the intake on the head. Don wants to change fuel filters first but don't think that's it. Gonna see if we can move it over to the other side so i can get the dependable ford out of the garage. Not sure how i'm going to get the truck back up the hill but i'll figure it out even if i have to hook it kinda close to my rear bumper and i drive back into the garage a bit at an angle. Long as the back of it's out of the street. As i don't know if the front bumper on the shotrod will line up but i know the front one on the truck lines up with an escort...been there done that one lol

Re: 2001 F150 won't start cold

The one that you will buy don't look like the other one, that's how you tell

And the truck will eventually start if you give it enough cranking time

Re: 2001 F150 won't start cold

I did find out that the 2001 has the CHT so it only has the one doodad, EHT which would be 2 doodads. 2002 they changed to EHT except i guess the 4.2 still had them. And the durn thing is under the intake but they say it's possible to do without removing it. Hoping so! Don insists the fuel filter and it probably could use a new one anyway.

After doing some research it sometimes can cause the oil 'gauge' and temp to be screwy at times and i've been having that issue with the oil gauge dropping to nothing when the truck is cold or been sitting 2 or 3 hours since it got colder. Found one place bout 15 people were having the exact same problem and was the CHT making the computer lose it's mind. I figured the sending unit was going on it. Haven't noticed the heat gauge go to hot but too focused on the oil. Though some never had the heat gauge go up to hot.

You need to check fuel pressure during the time this is happening.

Re: 2001 F150 won't start cold

It doesn't last long enought to check it and is intermittent. I picked up a fuel filter as it is well due to be changed anyway. It doesn't run rough or anything when i get it started or when the oil light idiot gauge is doing it's thing. It still won't start so today my son and i rolled it back down the driveway and i got the shotrod out and backed into the neighbor's driveway behind it and used the car with some big chunks of foam between us and pushed it up into the driveway on the other side so i can get out of the garage now at least.
Will be messing with it this weekend. Long time ago there was issues and it was the fuel filter but it wasn't doing all the other weird stuff and it would run rough off and on. I sure like my simple car. No computers or sensors....

Re: 2001 F150 won't start cold

We just finally got the gas tank back in yesterday. Fuel pump was intermittent and sounded like it was sucking air sometimes. Changed the CHT, change fuel filter and now it starts but won't fast idle. Haven't taken it for a drive yet, probably will today. At least it starts just have to keep my foot on the gas a tiny bit til it warms up. I read about cleaning or replacing the throttle body and saw mention MAF and an air control valve but i have no idea which it would be. Still no codes either. This fast idle issue is like it was for a while before everything else melted down. Anyway to test these 2 things?

Re: 2001 F150 won't start cold

Deb, it sounds to me like your idle air control valve is not working correctly. They get gummed up with carbon and stick sometimes. You can take them apart and clean them up. It is only two bolts and an electric plug to remove from the truck. If it is too nasty to clean, new valves are under $50. Real easy to replace as long as you can get to it.

Re: 2001 F150 won't start cold

I kinda got lost the last couple months and finally getting back! I was thinking maybe that's next on the list. It's having a melt down. It's still starting at least. Long as sometimes i give it gas soon as it starts then the idle picks up like it should. The oil 'gauge' dropping to zero is still doing it's thing but i hear no difference when it does that so think the sensor is going on that part. Truck sounds like it's low on oil all the time, always has since new, especially when it's first started. Thanks for the help guys!
