Is that what that is when My truck wont start? the engine cranks for a few seconds I wait and moment and the it fires up.? Also when I fill up my fuel needle goes wack. I know my tanks full but the needle shoots to empty and goes up slowly and back to empty. *SHRUGS* any ideas?

Replying to: liftedsierra00 (Jan 08, 2007 9:29 pm) It sounds like you and I have the same issue, in that it won't start the first time unless you crank it for a long time, but once it is running, it is fine. |

My fuel pump stays ON after the truck has been shut off... often runs the battery down if I dont disconnect it at night. has new fuel pump in the tank and a new switch thing,(like a timer switch)... we have checked out many electrical scenarios, just cant figure this one out! Please help! thank you

Replying to: seannoo (Jan 10, 2007 7:13 am) do you think that a truck like mine would have a timer on the fuel pump that stays on for 20 seconds after the truck is shut off? thats what my mechanic changed out last time he worked on it... I really have never heard of such a thing, but also, do you think that this timer and the relay might be the same thing? I hate my truck... but we just put a new motor in it, it didnt have this problem before, just the gas guage didnt work, this fuel pump thing started after we got the gas guage fixed.

Replying to: seannoo (Jan 11, 2007 6:57 am) It sure was nice of you to help me with my truck dilemma... The truck went back into the shop again last week, and I hope that we will finally get all the bugs worked out eventually. believe it or not your comments really helped me to persuade my mechanic to look at that relay one more time... they told me that the relay was the first thing they changed out, but after I had them check it again they said that when they pulled it out, that it had rattling parts inside it and they were able to get another replacement one at no charge to me. I havent gotten it back yet because the other thing they needed to change out was a bad pilot bearing, (clutch)..... it was ready today but they didn't have time to test drive it yet so I should have it in the afternoon sometime tomarrow. thank you so much for your help, and good luck to you with your projects always!

| Does anyone have a location for the fuel filter on a 04 3500 DRW crew cab, with 8.1L and allison tranny? I traced the lines back to the tank, and the only place i think it could be is either the tank or a box mounted on the underside of the bed. 1 line runs to it. | |
