Mackin 05-03-2005, 10:39 PM Have you changed the fuel filter? Open bleeder on the fuel filter housing and prime.If clear fluid is present then close and pump till hard.I have on occasion ended up with air on the clean side and a no start. Other than that a Tech II for diagnostics would be the next step. Good luck xtremfun007 05-04-2005, 01:14 AM Thanks for your help, I have tried that it doen`t seem to be pumping any fuel up to the filter. socaldieseltech 05-04-2005, 01:19 AM Did you open the bleeder and make sure there is fuel in the tank? xtremfun007 05-04-2005, 07:33 AM Yes, I did that also ,Is there a way to see if the injection pump an the lift pump are working correctly? Thanks for your reply specialagentPK 05-04-2005, 11:33 AM myu dads 2002 did something like this to him twice. the first time took it up to the dealer and the fixed something. 5000 miles later did it again. they ended up replacing the engine Grey Ghost 05-04-2005, 01:47 PM xtremfun007, Do you have anything aftermarket on your truck? Give us your setup so we may better assist you. If you are completely stock on the fuel system (no secondary filtration, etc.), the only "lift" pump is the one you operate with the palm of you hand on top of the filter. Gary xtremfun007 05-04-2005, 05:22 PM Thanks for the reply. Its bone stock , So I guess the only other thing it can be is the injection pump,what do you think? Thanks again for the help.Is there a way I can test the pump to be 100% ,That it`s the pump? Rockin 05-04-2005, 05:36 PM It is unclear from your post. When you bled the system ( pump by hand till only fuel comes out of bleeder ) did that work? After you tried to start, did you bleed again and get air? It took a few tries and it would star then die when I ran out of fuel. If you think no fuel is getting to the filter, priming is the first step. GMCSID 05-04-2005, 08:16 PM Thanks for the reply.

Thanks again for the help.Is there a way I can test the pump to be 100% ,That it`s the pump?There are many more things it could be before the injection pump. A Tech2 is needed. Make sure to check all fuses first. | ||
