I have a 93 w250 ctd, ill drive down the road for about 6 miles and the truck will dye and blow out alote of white smoke, then wont start for another couple of days, ive been told it might be a stuck injector but i dont know.

 

How old is the fuel filter?

 

Just put a brand new one on, i bought it 2 months ago had the tranny rebuilt, and drove it for 2 weeks with no problems then all the sudden, its done this twice.

 

When it is running does it run good or does it run rough?

 

Pull the fuel filter off and drain it into a clear glass or cup. Make sure you aren't pulling water in from the fuel tank. Even if you've filled her up with a known quality fuel, the specific gravity of water is higher than diesel so will sink to the bottom of the tank, right where your pickup tube is.

It's possible the injectors are sticking open, especially if the truck sat for a few years. That would suck.

 

When it runs, it runs great, and it could have water in the fuel but the truck did sit for about a year and a half and it wuz set up to run vegy oil, the fuel thats in the filter dosent even smell like diesel, ive been runing auto tranny fluid to clean it out, i called a performance diesel shop and he said the stuck injector could be leting compreshion into the injection lines, ive got new injectors coming so im gona try that first.

 

From past problem's w/ mine, white smoke always ment too much air, not enought fuel,,,( i could be wrong), but you said the truck run fine for a while.

 

ya wen it die's its doing it because there is no fuel in the lines, thats why i think its a injector sticking, i can take off the #4 injectore line and it will kinda start but runs rough

 

I would have a hard time believing it is an injector problem cause it runs good when it is running. I would think that if an injector was bad it would run bad all the time.

 

but were is all the air coming from then, there is plenty of fuel in the filter and the manual pump works fine, i think its eather that or the injection pump but idk,

 

Just because there is fuel in the filter don't mean it is good fuel. Also the lift pump could be bad or a bad fuel line could be letting the air in.

 

It could be bad fuel im gona drop the tank and drain it, all the lines ahve been replaced, but the guy i got it from was rining vegy oil so i know the fuel system is dirty, ive put 3 new filters on it in the 3 weeks ive been driving it just to help out,

 

The last fuel filter i took off, a big glob of goo came out of the drain plug

 

Veggie oil can have a lot of water in it IIRC. Draining and cleaning the tank is a great place to start.

 

they had a diffrent take for the veggie oil but thats what im gona do, i already bought the injectors but there the pod 50 hp ones so that will be fine
