Could it be a sensor?
Was the problem found to your 2004 F150? Was your problem similar?
I believe your injectors are hydraulically driven, with out oil in the high pressure oil reservoir the injectors cannot operate.
I have a 1997 F-250 7.3 turbo, it has stalled on me 3 times over the past few months all 3 times somehow my high pressure oil reservoir was empty.
After re-filling it the truck started up and runs fine.
Just don’t know how what is making the level drop out of the blue.
The engine turns over and coughs and sputters a few times but it will not start. I have tried restarting several times after waiting for various times to no avail. I've let the vehicle sit anywhere between 10 minutes and 1.5 hours and tried again. Waiting about 1 - 1.5 hours seems to work best and the engine will start normally. The only other factor which may be a coincedence is the ambient temperature has always been over 90 degrees F when this has happenned. I'm thinking a sensor or the computer is the problem?
Thanks
Problem Taking off whole drive train shook and power was low. After computer dianostics we had 1 coil bad and replaced some of both fuel and return fuel lines. fuel line filter.
now runs super. hit switch and it starts on first rotation and purs.
Last February (2011) we had a horrific freeze which cause the diesel to gel, even with anti-gel in it (-40F). It hasn't ran right since. It started out to where you could drive for a ways before it would mess up, now you can't even make it a mile down the road.
It idle's ok and runs ok at speeds up to 20mph ish. After that, it starts cutting out like it is running out of fuel. If you let it set for about 5 minutes, it will start up and run again for a mile or so.
We have replaced fuel filter, and fuel pump with no success. Dropped the fuel tank where we found the sock floating in black gunk. Completely drained, cleaned, blowed the air out of the lines, and filled back up with fresh fuel. Ran really good. Drove it to work (50 miles),ran it at 65-70 mph, ran wonderful. About 7 miles heading back home, it started messing up again, doing the same thing. Thought maybe there was some residual gunk that broke up, replaced the fuel filter again, still nothing. Drained the oil from the high pressure oil pump which was extremely thick, ran 4 cycles of fresh oil in it. and replaced the injection pressure regulator valve....Still nothing.....
Out of ideas but really need the truck back ASAP
The pickup is only used a few times per month (80k miles) but every 6 months or so I will be driving normally after 30 min to an hour and about 50 miles and come to a stop light where it will die. In the past it would start after cooling off for an hour or so. Now, not so much. Turns over fine but acts like there is no fuel.
Any ideas or recent break throughs??????????
