CHART A-3

ENGINE CRANKS BUT WON'T RUN

1.8L "J" SERIES

FUEL INJECTION (PORT)

Engine cranks but won't run, or Engine may start, but immediately stops running. Battery condition and engine cranking speed are OK. There is enough fuel in the tank.

Fig. 006 - Chart A-3 Engine Cranks But Will Not Run (1 of 4):

1. A "SERVICE ENGINE SOON" light "on" is a basic check for ignition and battery supply to the Electronic Control Module (ECM).
2. If the test light "blinks" while cranking, then ECM control should be considered OK. Be sure test light makes good contact between connector terminals during test. The light may be a little dim when 'blinking'. This is due to current draw of the test light. The test light bulb should be an 1847 (6.3 V) equivalent.
3. Secondary voltage (spark) is checked using a spark tester or equivalent. No spark indicates a basic HEI problem. If spark is OK the following checks should be made.
4. Use pressure gage. Wrap a shop towel around the fuel pressure tap to absorb any small amount of fuel leakage that may occur when installing the gage.
5. Throttle Position Sensor (TPS): If the sensor is sticking or binding in the wide open throttle position, the ECM will be in the 'Clear Flood' mode. The air/fuel ratio will be 18:1 to 20:1, and this may be too lean to start a cold engine.

Water or foreign material can cause a no start during freezing weather. The engine may start after 5 or 6 minutes in a heated shop. The problem may reoccur after an overnight park in freezing temperatures.

6. The fuel system should be considered OK if no trouble was found. Reconnect injectors and review Symptoms for possible mechanical problems.
