Hello all, I've got a 2002 F150 with the 4.6l Triton in it. 2WD.

I've got a small starting problem. Battery is less than six months old, cables appear to be corrosion free and the terminals are less than six months old as well- and they're on there tight.

I notice that the problem mostly only occurs when I have the A/C turned on prior to starting the truck, and it tries to crank but I may either have to try four or five times before it will fire up, or I may have to try it a few times and then turn off the A/C and then it will fire up.

After checking the battery and the alternator, what should I check next?

 

I have the same problem. I took my truck to a local mechanic two weeks ago and they indicated they had fixed the problem. I hadn't used the AC until today, and again it happened.

Could anyone please advise?

Thank you.

 

is the truck cranking over slowley or is it when you turn the key ahead the starter doesnt turn at all? my truck had the problem when i turned the key ahead the engine wouldnt spin over at all and it seemed that it happened most often when the ac was on it turned out i had a loose wire in the steering colume good luck
