Re: 2000 chevy malibu 3.1l no start
Got fuel pressure, spark, check engine light is on in the key on position, runs on carb cleaner, assuming for the time being there is not a theft system issue. Double check the injector harness connector that it's completely connected. It's in the area of the back of the alternator, 16 way connector. Pin A, pink wire, is common power, pin B, yellow wire, is CTS signal, pins C through H are the ground side of the injectors 1 (pinC) through 6 (pin H). Injector resistance is 12 ohms and acceptable range is 11.4 to 12.6 ohms. Don't go jamming a probe in the terminal but verify power is good in the RUN position, then key OFF check your individual injector resistances. Coolant temp sensor is connected right? If not, the PCM sees -40 degrees and it might not start with that much raw fuel. CTS is forward and below the thermostat, two wire connector.
