1997 Chevy c2500 with 5.7l vortec won't start.

Asked by Rusty Aug 22, 2020 at 11:45 AM about the 1997 Chevrolet C/K 1500 Cheyenne LB RWD

Question type: Maintenance & Repair

Replaced a very bad distributor,  cap, roter, wires and plugs. Also old fuel filter,
and fuel pressure regulator.  Truck has over 267,000 miles and the above parts
were all original. I have worked on cars most of my life. Cancer takes too much
of my money to afford to take it to a shop. Please help if you can. I have
checked several sensors and they checked out. Thank you for help. "Rusty"

If you know you have spark and fuel but it still won't run it's time to do a compression test. With that many miles on it a jumped timing chain is a good possibility. If all cylinders test very low or zero it's jumped timing. Hope that helps! Jim
