Dead Truck

[mosteen]

My truck had an o-ring go out on a plug located on bottom of high pressure oil pump. Replaced o-ring, put back together and it will no longer start. Will start and run on starting fluid. Did this plug possibly have a spring or something on it that if it wasn't put back it will prevent it from starting?? Any thoughts would be GREATLY appreciated! Thanks!

Welcome!!!!

Which truck do you have?

make sure the hpop is full of oil. i believe there's a check valve type deal in there that prevent's the oil from draining out. you may have messed that up some how and not known it.

Mosteen, this 7.3 could be a different, but "Starting Fluid"??? Ether? Big NO-NO in most diesels in general... Can cause all kinds of problems... Just thought I would throw that one in as no one picked up on it. It OK in Gas engines as they are low compression. But can blow hell of strain on a high compression engine.. (I might just be old fashioned and someone will come on and tell me it is OK on the 7.3... but I doubt it)...

As to your no start, sounds like a fuel problem for sure. Regards, Ranger

lone ranger, i didn't catch that. stating fluid is big no-no. that get's pulled in there and could come in cantact with a glow plug and flash back thru the intake. so put the starting fluid down and step away from it.

Thanks everyone for the info. It is a 2001 F250 Superduty. Still trying to find some info somewhere to try and save me some $$ by not taking it in somewhere.

get it started once, pull the small brass plug on the drivers side of the flat resevour that is front and center on your motor. there should be oil within a half inch of hte top. if its not full, fill it up throught that small hole. you can use ether this ONE time, if you have to, but dont do it EVER agian.......go run it HARD for about fifteen miles and see if that fixes the no start. if it doesnt, you have a problem in the HP oil system and we will need to go from there
