Been searching the threads and the more I read the more confused I get
Today I took the truck out - started fine - left the house - got about 15 miles down the road.
The truck started to shudder. Which had occasionally happened before (usually when the engine was not fully warmed up and hitting the highway). Dropping it out of overdrive for 30 seconds or so would usually solve the problem. So I thought maybe the trans was on its way out.
So I dropped it out of OD. Seemed to work. Then a couple miles down the road it did it again. Then it started doing it more an more. Then the truck was doing it in all gears.
The truck kept loosing more and more engine power and finally shut down (of course on a 4 lane highway with only half a shoulder).
Waited half an hour. It would crank fine but no start.
Called BCAA and had it towed home. (that's a whole other rant - make sure you get a flat deck to haul your truck).
So for the heck of it I went and got a fuel filter. When I changed it I noticed that the fuel was almost black. It was the first time for me to personally change it. When I watched a video online on how to change the filter the fuel in the bowl looked clear?
Changing the filter didn't change anything. Truck cranks over good and is trying to fire but doesn't
Have had hard starting issues before (left over 24 hours it was very hard to start) but over the last few weeks it seems to have gone away.
Have changed the GP relay - Glow plugs - Wiring harnesses and new batteries. Changed over to synthetic oil and yes as many have stated it definitely helped the engine to start better.
Recently bought the AutoEnginuity program. Haven't had a chance to learn it yet
but I put it on the truck to see if I could get any codes.
I've attached the pics of what I saw. There's a fuel pump code but there was fuel in the bowl. Any help would be appreciated. Thanks.
