95 7.3 power loss then cluter and no start

[gonente23]

all right so hi to every one i am new to thee site and i need some advice for my truck, I have a 1995 f250 with the 7.3 powerstroke and ever since i bought the truck it has had the some problem it would kinda stall out. and sometimes it wuld die then it would start rite up again. well the other day i pulled out of the king soopers and started to accelerate and i didnt have any power like it usualy does. well then it started to cluter real bad and then it died. well now it wont start and when i try to start it it tryes to start but it doesnt and it cluter real bad i need to get it up and running any ideas

maybe

There is a lift pump under the turbo. Mine went out once. Check on diesel in water seperator. If its empty might be lift pump, it has a check valve in it that fails........

 

[gonente23]

thanks

Ya thats what i have been told i do not know much about diesels but i love my truck i have put alot of mone?y into it and it freaked me out i thought the motor blew out or something i will check and let you know just curius wer is the the fuel water seperater and if i don have to replace it do i have to take out the turbo

 

[gonente23]

cear up my first post and some one please help

I wante to kind of clear up my first post with my problem, Wheni would drive it would spit or sputer and then sometimes dies. The other day i lost power and it sounded realy bad it was i gues you could say cluttering realy bad it was a horible sound someone please help???

 

[Truckin4life]

clutter like it would on a cold morning start?
I say check the fuel water seperator....
Tryin to remember where the fuel filter is on those trucks, take a look at that too...

 

[gonente23]

horible cluter

No not the the cluter in the morning it was like that but ill say around 40 times worse than that i will check all that you said and we will see what happens. another ? is if i pop the vavle on the fuel pool and emty it and then i turn the key on and it fills up then the fuel pumps are working correctly or no. if it fills that might just be the fuel pump in the tank filling it and there is not enough presure to start is what i thinking it will be but i dont have a clue

 

[bowtiehatr]

you only have one pump, the one in the valley of the engine. how many miles are on the engine? it sounds like a fuel starvation issue but there are a few other things to check. it could be a bad tank selector switch, either sending unit damaged or stopped up not allowing fuel to be pulled, or it could be injectors that are too old causing to much fuel spikes or allowing compression to come back up through the injector.

 

[gonente23]

230***

the truck has around 230*** i have put a new turbo new exost and new traning and t case also a newly rebuilt rear end i hope it not the injetors they are way to expensensev

Been there done that

Took my 7.3 to Ford, they said my problem was a switch for the tanks,CPS and replaced all of that. Tried to start it 2 days later and nothing. Found a International Tractor Mech, he said bring it by, I did and he showed me the lift pump. It had been loseing the check valve once in a while and allowing the diesel to leak ou tof the water seperater.

 

[wayfastxr]

Water seperater is ontop,center of motor. You unscrew cover and check filter. There is a drain petcock on the bottom. You will find it. Good luck

[gonente23]

Im Done

Well thanks guys for all the advice i got it done finaly. I had used a hammer and a screw driver to get the bolt out for the fuel line adn i finaly got the 1 1/4 inch wrench and i got it tight. I hade beeted up the blot alot and it would not seal at first than i put some teflon tape and tightend it with the wranch. it ,ade it so much easyer if i had the wrench th hole time it would have taken half the time. I am glad i didnt have to take out both my turbos that would have beeen a night mare. well thanks guys i am officialy ready and open for buisnes thanks, Nathan

you have twin turbos?

 

[wayfastxr]

Ya not sure on that, if there is 2, I would of pulled turbo--ssss. Mine had to come off. At least for me...........

 

[A_G]

as far as turbo(s) im pretty sure thats a typo.

as far as the lift pump goes, alot of time when that goes out youll end up with fuel in your oil. so id change that.

if you still have an issue, there should be two relays near the top of the engine, usually on the cowl (im going off medium duty btw) that controls the ICP sensors and other crap, replace both of them.

Believe it or not, but it has fixed a sputtering, white smoke (unburnt fueld/cold engine issue) for me before.
