Engine Mechanical problem
2002 Chevy Silverado V8 Two Wheel Drive Automatic 130000 miles
began checking fuel system because engine does not catch on first try. Nothing drastic, just have to turn it over twice usually. 58 psi with key on, engine off. 50 psi with engine running, but does not hold pressure at all after shut down. Drops immediatly to zero. No indication of fuel leaks noted. Book says possible leaking injector or bad check valve on fuel pump module. Engine seems to run smooth enough mileage ok. No check engine alarms shown. I'm guessing leaking injector would give rougher engine operation, so this seems to leave the fuel pump, but would like any recommendations or advice before I spring for a new pump and do the labor. Thanks
have the same problem?
