OBS wont start...help please!!!!!!

[strokersmoker1025]

ok so im new to diesels....I have basic knowledge of how they work. I just bought a 95 f250 about two weeks ago. last couple days its had a sparatic miss.. seemed to be a fuel issue. it was acting as if it was starving for fuel. since it has been sitting for over a year I figured bad fuel/filter. I drained tank. new fuel and filter and it ran like a top all day yesterday.. parked it last night,went to start this morning and it will crank but wont fire.. as im turning it over I have a significant amount of white smoke coming out the exhaust. I checked fuel bowl and it seems to be staying full... any ideas???? any suggestions would be great!!!! thanks

You're getting fuel if you're getting smoke.

Is your wait to start light coming on/off like normal?

Checked oil level? Check fuses.

Is the tach moving when you crank it?

See if you have fuel pressure when cranking. Scan for codes. Could be glow plug relay.....

yea wait to start light is working normal..oil is dead on the full line. I haven't checked any fuses. anything specific I should check?

 

[strokersmoker1025]

I just tried to crank it again, yes tach is moving slightly, and oil pressure is good while cranking

Like already said if your getting white smoke your getting fuel. Is it cold where you are? Make sure glow plug solonoid is working, I bet thats the problem if your getting cam signal (tach moves) and pcm power ( wait to start light). You can jump the gp solonoid with a screwdriver for about 20 seconds to see if it starts, if you don't have a way to test it. And make sure battery's are good.

it was roughly 45 degrees this morning. Im in upstate NY. Batteries are two weeks old. Ill try to jump the solenoid in the morning. Thanks!!!

I would definitely put the gpr and gps under scrutiny. I'd also run some diesel kleen through to clean any gunk out of the fuel system/injectors, you may find you'll have to replace that new fuel filter in short order.

plug the block heater in and see if itll fire up, injectors could be worn, or GPR is bad

 

[strokersmoker1025]

thanks guys.. I had to work late today so I didn't have time to mess with it,hopefully ill be done early tomorrow and can get it goin.. I got new injector/glow plug harnesses,new glow plugs, and a solenoid... hopefully itll all work

GPR, worn injectors, low compression. Prolly a combo of the all 3.

ok so I replaced injector/glow plug harnesses,gps,gpr, and I found a broken senor on my fuel bowl. local parts store called it a fuel tank pressure sensor. it was 28 degrees this morning so I plugged it in for half hour and it fired right up... smoked quite a bit for about 5 minutes but it hasn't run in a week... I went around the block with it and it cleared up. still seems to be starving for fuel in higher rpm..and has a slight lope on idle. if I unplug the icp it smooth out and check engine light comes on. bad icp?

if it changes the idle when you unplug icp sensor then its working. if no change then it is already in default. get a scanner on it.
