03 F350 6.0 No crank

[alp41104]

I noticed one day the oil pressure gauge took 4 seconds before showing me high pressure on the cluster while the engine was running. I know before as soon as I crank the engine the oil pressure was normal. The truck ran normal. A little while after that, it started shaking and when I stopped at a light, it died on me. I start the truck again but I noticed when I let my foot off the accelerator, the engine wanted to die. I had to drive holding the brake and gas peddle both to keep it from dying. I parked until the next day and when I tried to crank it nothing happened. Gave it a shot of ether, nothing happened. It doesn't even try to crank. I replaced the oil, oil filter and both fuel filters. Can anyone offer me any solutions that don't involve a dealer because I'm in Mexico for a few months with my family.

Sounds like it might be hydro-locked if it won't even crank over. I'm assuming your batteries are good. You might pull your glow plugs out and see if it cranks over. That will at least allow you to confirm that.

It spins over, but doesn't start, not even with ether. Sorry if I was confusing.

high pressure oil leak developed and when that occurs the truck will stumble fall flat on its face and die, unless you hold it wide open. Happened to me a few times. Had replaced a bad injector was driving it and watched the icp pid drop from 2-2800 down to 1200 and once it hit 800 i held it wide open all the way back to the shop until it died in the driveway.

Turned out the stand pipes and dummy plugs were fubar.

Also had a customer install an "upgrade" put a resistor inl ine of his icp sensor which caused the ipr to eventually fail which caused the same thing. Not that the screen blew out, the solenoid inside the IPR burned out from being commanded much higher than need be at all times. Only when people install a resistor to the icp sensor, it causes the pcm to think the ipr isnt doing its job so it commands it higher causing more Pressure to go to the injectors which is believed to give more power but really causes more problems... Ive seen it alot in 7.3s only once in a 6.0

Yep, I would also suspect a high pressure oil leak. Disconnect your ICP sensor and see if it fires up. The PCM needs to see 500psi of high pressure oil or it won't allow the injectors to fire.
