2005 F-450 6.0 won't start.. HELP!!
Ok. I have a 2005 F450 6.0 that won't start. It will run for about 5 mins and just shut off. Truck has 175k miles. Just did an oil change.
I was driving down the freeway and the HPOP went out. The mec replaced that. Ran for a couple days good with no problems. Went out to start it up. Ran good for like 5 mins in my driveway and just shut off. Will turn over fine but won't start. Later that night tried it again and started right up but same thing died after about 5 mins. Replaced the alternator cause it was not charging, replaced the ignition switch, crank pos sensor also. Still won't start. Any ideas?? Need help this is my business truck.
