CHART A-3A, ENGINE CRANKS BUT WILL NOT RUN
Battery condition and engine cranking speed are OK, and there is adequate fuel in the tank. If engine starts but immediately stalls, see CCC TESTS W/O CODES (TROUBLE SHOOTING) article.
"CHECK ENGINE" light on shows ignition and battery supply to the ECM.
Fuel pump fuse should be checked at this time and if blown, repair fuel pump circuit before proceeding. Secondary voltage is checked using tool (ST-125). No spark indicates a basic HEI problem.
This test checks if ECM is receiving reference signal and is controlling the injectors. If the test light blinks while cranking, the ECM should be considered OK. Be sure to check both sides of engine and that the test light makes good contact between connector and terminals during test. Use test light (J-34730-2) or equivalent.
This test checks fuel pressure using pressure gauge (J-34730-1). Wrap shop towel around fuel pressure tap to absorb fuel leakage when installing gauge.
The following can cause a "No Start" condition: An EGR valve sticking open, fouled spark plugs, TPS binding in the wide open position, defective cold start circuit or water in fuel, or a defective MAF Sensor
