Help!!

8 posts in this topic

I have a 03 F-150 4x4 5.4 Triton. 50,000 miles on it. Three times in the last 4 months it has acted up on me. What has happened is after driving for maybe a hour straight and shutting it off. I go back and try to start it within a few min. and it wont start. It will turn over and chug a bit and then die. It will start in a few hours and run fine again. The check engine light has never came on. The fuel pump kicks in when I turn the key on, but its like its not getting gas? Called Ford and they said untill it dies they wouldnt know where to start because nothing will show up bad when its running good again.Parts are not cheep, so where can I start?? Cant go anywhere without woundering if Im going to get back home. Also its not vapor locking, I open gas cap and still wont start. Thanks for any ideas!!!

I would expect 1 of 2 things. Fuel pump, or Idle air control (IAC). Next time it does it, try stepping on the gas pedal just a little if it starts then and runs, it could be the IAC. If it doesnt start then, turn the key on and off 3 times and see if it starts then, if it does it maybe a fuel pump. The first thing I would do, is try pulling codes out of it, then measure the fuel pressure, before throwing any parts at it. Parts arent cheap! I would lean more toward the fuel pump if I was to guess!

Have you noticed your fuel economy go down? I also like the cycling the key and light foot on throttle ideas. If those don't work go with throttle wide open.

Also its not vapor locking, I open gas cap and still wont start. Thanks for any ideas!!!

Vapor lock is the fuel boiling into vapor in the fuel rails due to excessive heat or low pressure. With the fuel pressures where they are in fuel injected vehicles this problem is virtually eliminated (higher pressure = higher boiling point). Removing the gas cap will have no effect on 99.9% of vehicles ever made. Cycling the key as shack mentioned will temporarily resolve the problem until the cause is determined.

Same thing happened to me but it was just inside the warranty. Lucky as it was a bit pricey including the tow.

    • If this crazy weather keeps up a guy might have to go to the mountains to have enough snow to ride.
    • I purchased a 20v 986 Dewalt brushless and used it with my Nils 8" and could not believe how fast it cut. Very close to my Tanaka motor as far as speed. My plan is to use it with my 6" Nils but wanted to give it a good test and it passed with flying colors. 
    • Pretty sure Bernie had that figured out. After the primaries I voted for "not Trump" You guys haven't picked up that liberals are still going for not Trump, even if that means Mike Pence (who from a political position standpoint is worse for liberals).   Instead you have Trump, a man incapable of taking any form of criticism regardless of how irrelevant it is to anything. Why do I post the crowd sizes? Because Trump, in a speech given only to members of the CIA, thought it was important enough to mention, as well as to have a team of his own people there to applaud when he mentioned the size of the crowds.
    • Here's the exact reason why I encourage everyone to buy the digital readout.  After getting holes drilled and everything setup, I always run my bathroom roof fan/vent to get rid of the moisture as the slush on the floor gets melted.  Yesterday I cranked the fan on max which moves some serious air, but I forgot to crack a window, which caused it to actually suction the CO from my water heater back into the house through a propane line pass through.  I looked up and saw 30ppm on the CO detector, which isn't high, but an indicator that something wasn't right.  All it took was cracking a window and turning down the fan for a minute and it was back to 0.  
    • You do realize the person you wanted to be president couldn't even understand the proper protocol for setting up a cabinet level email account don't you?    
    • I looked into fiberglass a few years back for a build.  I decided against it as it needed a wood backer.  Not sure if there is a different product out there now.  
    • finally got out Friday, put on 75 miles in the heavy drizzle, not the first time I have riden in the rain. the trails were OK, I rode in aitkin co. that doubles the miles I put on in the last two years.
    • they load tested the battery and said it was bad, everything else they said was fine, they put in a new battery. tried it today after sitting since Tuesday, and it started up fine, problem fixed.   I have a 2002 grizz carbed, and that sat for close to 3 months, went to start it this weekend, and it cranked for at least a minute (very cold blooded machine) and it started, it has the same battery that's in the Polaris.
    • Precious snowflake Trump needs a safe space from the media apparently.   I suggest you familiarize yourself with the word kakistocracy, because that appears to be the road we will be traveling down.
    • No,I am saying those who are left with jobs are working for those who Obama is happy to give money to for nothing. He was as bad as it gets in terms of getting people back to work after a recession especially when you factor in the amount of money he spent to do it.
