I am stuck in Edwardsburg Mi. I have an 08 2500 4x4 standard with 420,000 miles on it. I been using the smarty sr with cal delete for about a yr now with no issues. It is set at the lowest possible setting for fuel economy. The other night I pulled in my buddies drive way and backed up on a small incline. The truck began running really rough like it was hitting on about 3 cylinders. I turned it off and waited a few minutes it fired up still running rough. I was a little low on fuel about 1/8 of a tank. The next morning I tried to start it but it would not start. It turned over fine but would not fire. I changed the fuel filter since I had a spare in the tool box. That did not help. It attempted to crank a couple times but would not catch. I checked the codes with the smarty but it is not showing any codes. I tried the spare key with no success. It now just turns over but no start. I am from Tx and would like to get back down there. Any suggestions would be greatly appreciated. This is the first time the motor has failed to start or given me any issues at all. I just need a starting point. I did open the drain on the fuel filter and turned the key on to see if the lift pump was working and fuel sprayed out. So I know the lift pump is working. Any help or suggestions would be greatly appreciated. I would hate to have to drag it to a shop since I don't know of any here. My buddy is not sure about the local shops and how they are with a diesel and a dealer is out of the question for the prices. Thanks again for any in put or suggestions.

 

Did you loosen line going into cp3 to see if you have fuel that far ?

 

I cracked open an injector line on the rail and cranked it over and got some fuel on the intake. I am wondering if the fuel release valve may have gave way. I don't think I got enough fuel when I cracked the line open. I know I have fuel up to the injectors just not sure how much pressure they have. No gauges or many tools to work with.

 

I managed to get it cranked on Break cleaner. Got it off the incline and it cleared up. It is still running rough with a little smoke. I guess it is time to put in a new lift pump. When I got the truck turned around my fuel level is about 1/8th over a 1/4 tank.

 

Unplug the AFC on cp3, see if it starts and runs any better.

 

I did that and it did not help. I put in a new lift pump and seems to be doing better. I feel safe driving it again. Thanks everyone for all the input and help.

 

Did you find the problem to your no start?

 

Hey jkidd! It was the lift pump. Changed it and working great now. Thanks for asking.
