Ok guys I got a tough one and I hope yall can help me out. I'll go into as much detail as possible and if anyone has any questions for me please ask.

So here goes, I was drivin home from class yesterday and got stopped up by a car makin a left. After the car got cleared I gassed it and blew the normal amount of black smoke out then when I let off the accelerator the engine shut down and has not made a pop since. I rewired some stuff comin off the battery beacuse of corroded wires and put a new connector on the unit on the drivers side of the injection pump and no luck. So I pulled the main feed fuel line off the front of the injector pump and cranked it over, plenty of fuel there. The oil has no diesel fuel in it. I cracked the injector lines and cranked it over. It had a lil bit of air but fuel popping off all 6 injector lines. Tightened them all back up, tried to start and it wont fire and no visible smoke out of the exhaust. We also pulled the #1 and #5 valve covers off just to make sure the cam was turning and everything looked good. The turbo is spinning freely and the truck seems like its got good compression by how hard the starter is workin cranking the truck over. Ive never had to crank on it that much cuz it usually fires right up with a touch of the key. I dont have a fuel pressure gauge, I know Iknow, I need to get one but there seems to be plenty of fuel. So if anybody has any ideas on what the problem could be all help would be greatly appreciated. I think I covered everything oh BTW its a 1989 Dodge 250 4x4. It has always run like a top and I definitely need it back. Thanks for the help.

I forgot to mention Ive got 12 volts goin to the fuel shutoff solenoid. Checked with a multimeter

 

might be pulling air @ fuel heater o'ring if loose or if o'ring is bad

any fuel leaks?

 

You may have 12V but that doesn't mean its not stuck. It certainly sounds like something with the pump. A bad cam or bottom end would give you totally different issues. Basically, if you have nothing coming out of the exhaust, then nothing is going in. Worst case right now is you may have to put a pump on it.

 

This is my buddys truck i helped him try to get it going we opened the main fuel line on the pump and there was fuel coming out. we dont think it could be a timing issue cause its all gear driven the thing that im leaning toward is that the pump might have just quit. There is fuel there at the injectors it just wont make a signs of firing at all not one little pop!!!

 

i feel your pain man i have had 100% of the exact same problems you are having. happened to me last week was running fine and then boom stalled at idle and wouldnt fire since. same story, power to everything fuel at the injectors with a little air and cam is turning. had a diesel tech come check it out and the injection pump is shot. definitely not what i wanted to hear at all but thats what it was. sounds like your having the same problem.

hope it helps

 

I'll start working on it again tomorrow. Ive been playin with the FAA all day today

 

try sending 12 volts to the fuel solenoid and listen for a slight click. Basically make sure the fuel solenoid is actually working you can have power there but nothing happening

 

Jason, gut the fuel shut off solinoid and report back!

 

will the pump still put some fuel out even with the solenoid not working? because he said there was a little bit of air but still had fuel coming out of the injector lines. mine did the same thing.

 

Yes, but not enough to get to pop off pressure
