Hey guys you have a really informative forum. I have been looking around and havent seen anything that is an obvious fix to my problem so I figured I would get your thoughts.
Here is my problem: I Bought a 94 GMC K3500 and it ran just fine for a while after I bought it. After having no problems with it for several days it just died one day. I was low on fuel so I went and grabbed a five gallon can and put some fuel in it and it cranked fine. Next day it died again and I had only gone two miles so i knew it wasnt out of fuel. It hasnt cranked since.
Looking around online I found the PMD was the biggest problem for these things. Bought a new one, popped it on and nothing changed.
A diesel tech here in my town told me to try a CPS. Didnt help.
I thought it was the lift pump, put a new one on and ran a wire to a switch so I could turn it on and off and make sure it was on. I can crack the t- valve and poor fuel on the ground so I know its getting fuel to the IP.
At this point I figure I have to bite the bullet and put an injector pump on it. Ordered a new one and put it on. Still nothing changed.
I pulled one of the injector lines off and its not getting any fuel at all. Not even a drop. Thought maybe it was vapor locked so I took all of the lines off and turned it over. None of them are getting any fuel.
I got fed up with it and took it to the chevy place and they said I needed a new IP. I told them I just put a new one on and they insisted that it was bad, so I put the truck on the trailer, took it back to my shop, took the pump off and sent it back to where I got it from. Got my new pump in and figured I wouldnt take any chances and took the truck to the Stanadyne shop thats a few hours from my house. They put the pump on, timed it, and still no fuel to the injectors.
I spent several hours cleaning all of the grounds and chasing down any wire that I thought might be even a little bit damaged. Thought maybe it wasnt spinning fast enough so I put 2 new batteries in it. Nothing has helped.
All I can think of is that the solenoid isnt getting power and not letting fuel through? Im not sure what controls that. Its not throwing any codes so I dont know what to look for.
Sorry for the long winded first post but I was hoping to be as informative as possible. If you need any more info let me know.
Any help is very appreciated.
Thanks,
Justin
