CHART A3 (1 of 2) - ENGINE CRANKS, BUT WON'T RUN (2.8L)

Battery condition and engine cranking speed are okay, and there is adequate fuel in the tank. If engine starts but immediately stalls, see INTERMITTENTS in the TROUBLE SHOOTING tests of the CEC TESTS W/O CODES article in this section.

NOTE: Test numbers refer to test numbers on diagnostic chart.
  1. This chart assumes that battery, condition and engine cranking speed are okay, and there is adequate fuel in the tank. If engine starts but immediately stalls, see TROUBLE SHOOTING in the CEC TESTS W/O CODES article in this section. A "SERVICE ENGINE SOON" light is a basic check for ignition and battery supply to the ECM.
  2. No spark indicates a basic HEI problem.
  3. This test will determine if the ECM is receiving the reference signal and controlling the injectors. This test could also be performed at the 4-way injector connector by using a test light between terminals "A" and "D".
  4. Using Pressure Gauge (J 34730 1), wrap a shop towel around the fuel pressure tap to absorb any small amount of fuel leakage that may occur when installing the gauge.
