Fuel system question... lost power
I hope somebody can help me out with this: If I pull off the fuel filter lid and then crank the engine then the filter canister should fill with fuel... right? Mine doesn't. I gradually lost power over 10-15 seconds recently and now it won't start. It was about 10 degrees F at the time and hasn't been above about 15 deg since. The fuel in it is a winter blend. I'm assuming there must be ice in the fuel lines; I haven't used any diesel conditioner in awhile. I'll be warming it up today, but it would help if somebody could answer the question above. Thanks.

Yes, the fuel bowl should fill as you crank the engine, and the symptom you describe when it dies certainly sounds like an issue with the fuel delivery. For a test you can fill the filter bowl with fresh clean diesel or something like Diesel 911 and see if you can get it to fire that way. Warming it up should help as well.

Thanks Nate, that helps. I have a couple of heaters under it now.
By the way, on your '96 do you have any kind of diagnostic tools or software? I gave up trying to find something a long time ago.

Actually, I don't personally have one (yet) but I am borrowing an Aeroforce Scangauge that is able to do some diagnostics and pull live data from either truck. That's probably your most economical route to go. It will pull trouble codes, reset the check engine light, run engine diagnostics and real a bunch of parameters while the truck is running. I definitely need to get one for myself.

Are you running winter blend fuel? What's the fuel level in the tank you're trying? Did you try the other tank?
