UPDATE: I replaced the lift pump today and bled the system. The truck fired right up. I noticed that now while its idling if I rev it (snap throttle) I get a nice little puff of black smoke. I didn't do that before I replaced the LP. I test drove it down the street and noticed that if I mat it and the truck downshifts it also let's out a little puff of black. Not sure if this is normal. Kinda looks cool tho . I spoke with my old service director who is a huge diesel guy.( did I mention I was an automotive tech for 14yrs? Gas motors only tho) he said he also thinks I should drop the tank that the pickup filter is probably clogging. So guess that's my next step.
