#77 of 510 Problem starting after sitting 2001 GMC Sierra 1500
Sep 03, 2008 (8:49 am)
Hey fellas, don't no if any of you can help but here's the problem. My 2001 GMC Sierra 1500 4.3 L has a hard time starting after it has been sitting for a day for two. The first few times I noticed it I thought the battery was dying. It would take 3 - 4 tries to get the engine to turn over.
I've checked the spark, its good. I just put a new battery on and I know its getting fuel.
When I think it's just about to catch I release the key and it sputters for a bit before quiting.

There is a check valve in the fuel line. If the valve fails, it allows gas to drain back to the tank. If that's the case it would be hard starting till the fuel pump can pressurize the gas in the line. Usually takes up to 10 seconds. A good way to test this is when starting leave the key in the "on" position for 10-15 seconds. If your truck starts right away, you know the check valve is the problem.

Thanks to all who posted to my problem.
After chasing my tail for two weeks I installed a new fuel pump and filter. It starts right up.
I don't understand why when the old pump showed 70psi when you first turned on the switch and would hole 50psi while running. Anyway, for any of you that may be having trouble like mind change the pump it doesn't cost that much.

#83 of 510 Duramax Engine Starting Problem
Sep 25, 2008 (8:32 am)
I have a 2003 Chevy 3500 that only wants to start in the morning. When the engine is warms up it does not want to crank right away sometimes not at all. I have taken the truck to two different dealers and everything looks good on there computers. I'm not sure if it is electrical problem of fuel problem. I installed a new fuel filter thinking this could help but no luck. Can someone help me out?

Sep 30, 2008 (8:44 am)
How do you access the intank fuel pump and do you have to drop the tank....I am having the same problem with the truck just dying on me...I changed the spark plugs, the fuel filter and the air filter and still no luck with it starting. I can hear the fuel pump running but my problems seem to be the same as everyone else so I again need to know it the fuel pump and screen are the answer....and how do I get to it....Obyone, do you have any ideas??? Does anybody have any ideas? I need my truck----and I need it now....

had same prob on 96' gmc sierra, slid the bed back about 2ft after unbolting it(four on each side) and disconeccting two grounds, after that, piece of cake. make sure you replace wiring. usually what goes bad.
#86 of 510 Battery goes dead on 08 sierra after onstar report
Oct 09, 2008 (8:28 pm)
I have an 08 sierra with onstar.In June the battery was stone dead on a Saturday morning. I boosted it and took it back to the dealer. They checked it and nothing showed. It has an active management alternator on it also. It is hard to get used not seeing the alternator charging all the time. I thought that was the problem but it checked out. On the last Saturday of September, the battery was dead again. The next day, I received my monthly onstar report. I checked my old emails and the last time the battery was dead was the day before the Sunday onstar report. As it turns out, the onstar diagnostic runs everything on your truck but the lights for six hours. If your active management alternator hasn't been charging the last time the truck was driven, your battery is stone dead after the diagnostics are transmitted. Supposedly, there is a GM bulletin on this problem, but what is the cure? Get the onstar disconnected? Anyone else have this problem with their 08 truck?
