Engine Mechanical problem
2002 GMC C1500 6 cyl Two Wheel Drive Automatic 76,000 miles
4.3L V6, was having problems with vehicle idling too low (enough to stall) while in gear at a stop. I've replaced the fuel filter, all spark plugs (w/ proper spacing), replaced air filter and replaced the IAC valve sensor. Also cleaned out the top of the throttle body. All of these replacements were done at the same time without attempting to start in beween. The truck will not start now. The engine turns, but will not turnover. No codes registering on the computer. The fuel pump was replaced this January at somewherer around 70,000-72,000 miles. Battery is a Optima Deep Cycle (yellow top) installed last Jan or Feb. Also, during attempts to start the engine seems to lock up or fail to continue to turn (hit and miss). My next guess is timing belt? Any help would be helpful.
have the same problem?
