Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, I'd be happy to help! First, is it cranking without starting, or is it not cranking at all?
Also, what's the engine size?
Ok, did you replace the fuel filter just for maintenance, or was it not starting before? Do you have access to diagnostic equipment to check fuel pressure, spark, and injector pulse?
Timing chain issues are very common on these, as well as anti theft problems. I'd like to eliminate as much as possible though.
Ok then we need to check fuel pressure. Do you have a fuel pressure tester? If not most parts stores will rent them out. It is possible that it's a coincidence as well, timing chain problems usually occur on startup. The fuel pressure on this engine is checked by installing the tester in the supply line in series, not to a port like most. Fuel pressure spec is 41-47 psi.
His there, I am Cam. If you kick the bottom of the tank HARD with someone trying to start the engine, does it run?
