Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello, my name is ***** ***** I'm here to help get your problem solved.
Have you monitored pressure when it runs good and compared to when it bogs?
Thanks for info, this most likely means fuel pump is problem as pressure regulator wouldn't be intermittent. Since problem is intermittent it would be hard to test to be 100% sure but I'd feel safe replacing the pump. I'd go ahead and replace the filter first then if problem still exists replace the pump. To know for sure you could check pressure at filter during problem, if good at filter but low under hood this would mean regulator. If low at filter this would mean the pump is problem. But I'm assuming it runs better when cold so pressure might test out fine by the time you were able to test at filter which is why I'd just replace the pump. Let me know if you have more questions, thanks.
