I was pulling my boat and all of a sudden my 2003 f150 with a 5.4 shut off. Looking at the dash the oil temp light came on along with service engine soon. Towed truck home now it won't even crank. I've only had this motor for four years probably doesn't even have 50 k miles. No loud clanking prior to shut down either. Any suggestions on the problem or why it won't crank?

 

Do not take the battery cables off yet for any checking but DO see what code is set first.
If you do, you lose the code.
Report the code you have accurately. We will do the description of it.
Then the diagnostics repair can begin.
Cranking concern takes second place under these conditions so the trouble indicator is not lost first.
Good luck.
