Fuel pump shut-off switch?

I know this isn't a Van forum but being Chevy guys i'm hopeing you can help me out. My mom has a 2000 Astro AWD and the starter died yesterday so we tow it out to my place and R&R it and now it rolls over fine but no fire? Now the tow vehicle was a stick and and times the ride got pretty jerky and i'm wondering if anyone knows if these have a fuel cut-off switch? Thanks

I'm pretty sure there isn't a shut-off switch. Can you hear the fuel pump running? You can try pounding on the center of the gas tank with a rubber mallet. It worked for me when my fuel pump started going out on my '96 chevy.

No there isn't a fuel pump cut off like Ford uses. GM uses a oil pressure switch to run the fuel pump. When you turn the key to run the computer runs the pump for 2 seconds to prime the fuel rail. once the engine is runing and has oil presure a sender closes to ground and turn the fuel pump relay on. FYI the fuel pump relay and the a/c relay are the same on your Mom's Astro.
Prob late info hope you got it going anyway
