Have you checked your fuel filter? If it needs replacement, it will restrict the flow of fuel thereby perhaps creating the symptoms you have described. This needs replacement regularly or it's remotely possible that you could damage your fuel pump which is located in the fuel tank. Fuel pump replacement is very expensive should it be needed (over $650.00 +) Note: As I understand it, the fuel pump is cooled by gas in your tank so it is important to keep at least 1/8 tank of gas in your tank at all times while running the vehicle to be certain you are not overheating the pump and shortening its service life. Anyone capable of crawling under the van can easily replace the fuel filter on most of the GMC Savanna/ Chevy Express models in about 5-10 minutes with just a ratchet/socket combo or wrench (to remove the bracket bolt that holds the filter in place) and a needle nose pliers (needed to squeeze the quick connect tabs that connect the lines to the filter). The correct filter will cost about $16 - $25 at a Walmart store. They are much more expensive at the dealer or parts supplier ($35- $55)!

Had battery fully charged tried to crank 2000 chevy 3500 and battery died within 3 tries,truck would not start.what would cause battery to die so fast?


The battery based off of its design and plate size can only supply so many amps. Even a battery that is reading 12 Volts could be in bad enough condition that it wouldn't provide the necessary cranking amps.

could be fuel elated, there are two fuel pumps, the high pressure pump to feed the injector system and the lift pump to get fuel from tank to the high pressure pump. Check fuel filter also and start there. The fuel pumps are expensive. What have you checked so far and eliminated?

Starts then dies


Aftermarket pump or OEM? If aftermarket, take it back and get a new one. Before you go through all that though, you may want to check the fuel pressure. You need to check the specifications on what the pressuresupposed to be for this model.
