I know you changed the LP, but have you tested the OPS to make sure it is still working? A new LP but bad OPS will not make the LP runs much better. We have about 3 this week so far here with that same case.

no i have not changed ops yet but if i can find it today i will i used this truck to tow my toys around . Do you know where i can find a diagram for turbo i dont now if i got the the vac lines hooked up right there a yellow one from vac pump and a black one from waste gate the run to the sionode the controlls it wastegate but dont know which ones goes where on the the silonode

I'd say change the fuel cap if you have a *large* vac in it. Also, if I understand your checklist correctly, your SES bulb seems to not be working correctly.

"2a. Service Engine light does glow during start/cranking/bulb check: Yes/No no"

"23. Upon unscrewing the fuel cap, do you have a large vacuum formed in the tank? yes/no yes"

That's what pops out at me.

well the check engine came on b4 when i a turbo issuse then i had a brake light switch go out not seen it since as far as the fuel cap yea it got alot of pressure on it mor ethen other car i ever own btw this my first diesel. does fuel cap have to be vented ??

well i just went and look i got 2 injectors leaking. I guess i have to buy a new set of them cooper rings

Yes, it should be vented.

ok i try that and the ops any one know what size those cooper gaskets are for the injectors cant get a kit today so i was going to try to find some

got vacuum going to the wastegate? without vacuum the wastegate solenoid isn't controlling the wastegate and you'll get no boost. without boost you'll have black smoke when accelerating and no power.
