I'M FED-UP ALREADY AND DONT HAVEANY HELP!!! bUT I'M ALMOST POSSITIVE IT HAS TO DO WITH THAT STARTER, IT SEEM'S LIKE THE STARTER WASN'T INSTALLED PROPERLY! IT WILL START AFTER ATTEMPTING TO TURN IT OVER SEVERAL TIMES! BUT NOT UNTIL THE CONTROL MODULE LIGHT ON THE DASH BLINKS. THATS WHEN I HAVE HOPE ITS GOING TO START!

Would you please tell me what light is lighting. Do you have a strong spark at the plugs. It could be the coil, ign module or distrbutor.

Customer Concern: Stalls when placed in gear or when turning the power steering.
Tests/Procedures: 1. Test the pick up coil output while cranking, pick up coil disconnected, should have 700 millivolts AC.

2. If lower than 700 millivolts, replace the distributor shaft and the pick up coil.

3. Replace the distributor shaft and pick up coil.

4. Test output again to determine if the new shaft is OK.

5. Check for vacuum leaks, upper and under side of the intake manifold.
Potential Causes: Distributor Shaft
Pick-Up Coil

Try your ICM? Fixed mine for a few weeks, now same problem, starts when fuel starter is used but not getting fuel, wont stay running. I'v done the fuel relay, filter, pump with strainer and new harness, bought a new computer and now I get error codes... feel like iv accomplished something... Now the computer says I need a coolant temp sensor, could this be a fail safe for the engine?.. Ill reply if this changes anything.
