Ok so the truck starts perfect when cold. If i drive for twenty minutes or more and shut it off, it wont start smoothly until cold again...if i try n start it i have to constantly give it gas to keep it running for the first few minutes. Truck is not excessively hot, needle doesnt pass the center of the heat gauge. What could be the problem? Im thinking starter contacts or fuel pump....

 

Does it actually turn over when its warm?

Check the temp sensors and the cold start sensor. Theyre fun to get to

My old truck had cold start issues. It would idle fine, soon as i gave it gas it would shut off.

 

Just some follow up..the temp sensor is new...didnt check the cold start sensor...but did put in a new fuel pump and the problem issolved
