#81 of 193 Starting Problem Resolved by lynn0335 Sep 21, 2008 (4:28 am)
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. Thanks again. Lynn Davis

#83 of 193 Duramax Engine Starting Problem by brokedown123 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?
#84 of 193 Problem with starting 2000 1500 Silverado by danamac Sep 30, 2008 (8:44 am)
Replying to: mcgregor45 (Sep 06, 2008 1:02 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.... Replies to this message: pbridges (Sep 30, 2008 3:32 pm)

Replying to: danamac (Sep 30, 2008 8:44 am) 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 193 Battery goes dead on 08 sierra after onstar report by paul_27 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?
#87 of 193 Hard Cold start. by civicpilot Oct 13, 2008 (1:38 pm)
Hello All, I have a '96 GMC Sierra. 5.7 liter. For the past month or two has been a little hard to start when the truck has been sitting for 5 or more hours. however the second it starts I can shut it right down and have no problem restarting. after leaving it for 5 days became impossible to start when cold without starting fluid. again the moment it starts I can shut it off and restart it immediatly with no hesitation. I replaced all plugs and wires, Battery, Fuel filter, to no avail. changed fuel pump yesterday and now it wont start at all. Pump is running and fuel is getting to the pressure check valve on the fuel rail.   PLEASE HELP!

Replying to: civicpilot (Oct 13, 2008 1:38 pm) Yes but sounds like the check valve has failed since it doesn't hold the pressure after 5 hours and thus the hard starting. Replies to this message: civicpilot (Oct 13, 2008 11:22 pm) obyone (Oct 17, 2008 7:51 pm)
