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 do not believe that they do. you may want to check the fuel pump relay as this is a common problem. failing that...looks like you're going to have to break out the old test light and start taking jabs at some wires.
good luck
