The fuel pump in our 03C190P failed about two years ago. I had noticed a "hesitation"/loss of power when pulling on to a freeway entrance. Noticed it, but not enough to cause a problem. Then, over the next few days, had more issues with bucking/loss of power when climbing hills. Thought at 1st I had a tranny issue with it slipping. Tranny service center said all was good, likely fuel. Sure enough, climbing east out of Salt Lake City (at night, in rain, in a construction zone...) could barely make 10 mph. Limped to an exit. Van never totally died, just no power. Next day spent 8 hours at GM dealer in SLC with van on lift. New fuel pump installed after diagnosis of no fuel pressure. Point of interest - genny fuel supply comes from fuel pump, too. Apparently a pass-thru port. Back on road home. All is now good. ST
