Chart A-3 - Engine Cranks But Will Not Run: Notes

1993 Chevrolet Sportvan G30, Van Passenger, 7.4 NSECTION Notes
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 1994 GMC Vandura Special, 1994 GMC Vandura, 1994 GMC Rally Camper Special, 1994 GMC Rally, and 1994 GMC Forward Control. However, it is still accessible from the selected car via links, so may be relevant.

This chart assumes battery condition and engine cranking speed are okay, there is adequate fuel in the tank, and glow plug system is operating okay.

NOTE: Test numbers refer to numbers on diagnostic chart.
  1. A MIL on is a basic test to determine if there is a 12 volts supply and ignition 12 volts to PCM. No DLC may be due to a PCM problem and CHART A-2 will diagnose the PCM.
  2. This step will check to see if there is an inject command coming from the PCM.
  3. This step will check the ground circuit.
