Hey guys, sorry to be a bad-weather poster, but I need help. I can't get my '92 D250 going.

Thursday I was driving home from work. I was coasting to a red light at about 30mph when I noticed the truck died. No warning signs prior to that, just dead. While still rolling, I popped it into neutral and cranked it with no luck. Stopped rolling, tried again, no luck. Not even a sign of wanting to fire.

Came back to it Sat. morning after doing some research on the forums. I started thinking that it must be something involving the fuel cut solenoid. I am lucky enough to have Alldata access through a buddy of mine, and info from there said that if the solenoid is the problem, all you have to do is remove the solenoid (note: it takes a 24mm open end, in case anyone needs to know) and then take out the solenoids plunger and spring, reinstall, and it should start after that. Did that (which was a pain, by the way) and still no luck.

I checked the lift pumps fuel output when cranking and that seemed to be more than adequate. I also cracked open the inj. pump fuel inlet line and cranked the motor to make sure fuel was there, and a healthy amount spilled out. Finally, I tried bleeding fuel at the injectors multiple times. I was able to get a healthy flow from the #2 injector, and a bit of fuel from the #5, but not even a hint of any from the other 4

The truck has plenty of fuel in the tank. I did recently crank down my AFC star wheel a bit, and I rotated the fuel pin, but I really don't see how those changes could have done this. Any other suggestions would be greatly appreciated!

If you are getting fuel to the injection pump and no fuel at the injectors that means the injection pump is the cause of the no fire. When you took the shutdown soleniod out was the rubber on the end all chewed up? Sometimes they will rip the rubber right off of it and it can clog up the delivery valves. This usually results in the truck not shutting off with the keys although I have seen a ripped plunger still shut a truck down. But it sounds like a bad injection pump to me.

Had the exact same thing happen to my 91, an it was a bad injection pump!

 

I had something similar happen to my 91. We pulled the pump and both springs in the head were broken and the piston was seized. Hope you fair better

 

Everything on the solenoid appeared to be fine, nothing chewed up or missing. The #2 injector seems to be getting fuel, just not the others. The pump got re-built in 2006 and has maybe 70k on it, so that's a real bummer. Any diag that I can do with the pump to confirm that that's it?

 

Same thing in my 89 man. Injection pump. It had sheered the key off the shaft that drove the pump and I could only get fuel out of 2 injectors. It's just the fuel the lit pump is supplying and the lobes in the pump for those 2 injectors are slightly open. Sorry for the bad luck, but replacing the pump is not as large of a task as you would think.

In the sticky there are VIDEOS about how to do it, and I've seen good pumps getting sold in the classifieds for $300-$500. Good luck man

There was a Non I/C pump on there too, but for pure bolt on purposes, you need a pump from 91.5-93 like the one I posted there.

 

Very helpful, thank you! Looks like I have a new project to undertake.......
