Well i just bought a 2002 3/4 ton with 154000miles truck is very nice!
I have been having a problem getting it started when I park it on the slope in my driveway [verymad] I already replaced the LP it was dead :( But i am still having a problem getting it started when I park it with the front of the truck higher than the rear! Any advise on what to look for?
Hopefully the IP wasint damaged [redface]

Sounds like fuel is draining back into the tank. Try bumping the starter and let the pump run for 10 seconds or so before you try & start it. If that helps, look for fuel leaks from when you installed the LP? Did you get all the rubber washers back?

You are gonna need a fuel pressure gage.

Yes I used new rubber washers. What is the best way to go for the fuel psi gauge. The light kit or a gauge?

One more thing do I need to worry about the KDP on a 2002 or is it only on the 12V?

Gauge....you can read it.

No worries for you.

Also test your overflow valve as well. If its stuck open, it could drain fuel back to tank as well.

Thanks for the replies gentlemen!!
