oh yeah......got fuel.......got fire(spark)......just a bad noise like the starter is not engaging. But when the coil wire is removed and the engine cranked, the noise goes away!!

Below is a bulletin that I think applies. I have seen this before. You need a crank sensor and if you still have a noise, check the teeth on your flywheel.

Condition

Some customers may comment on one or more of the following conditions:

 

• Backfire during crank/start

 

• "Kickback" during crank/start

 

• "No" start

 

• "Slow" or "hard" start/crank

 

• "Grinding" or unusual noises during crank/start

 

• Cracked or broken engine block at the starter boss

 

• Broken starter drive housing

 

• Broken starter ring gear on flywheel

 

• Any combination of the above

 

Cause

A condition may exist that allows the crankshaft position sensor to command up to 50 extra degrees of spark advance during engine cranking only. This in turn exposes the engine to higher than normal cylinder pressures which may result in an inoperative condition to the starter drive housing, the engine flywheel starter ring gear, or the engine block at the outside edge of the starter boss.

 

Correction

Inspect for a stored powertrain DTC code P0338. This DTC will NOT illuminate the "Service Engine Soon" light. If this code is stored, the Crankshaft Position Sensor, P/N 10456607, MUST be replaced and the remaining components inspected for damage (engine block at the starter boss, the starter drive housing, and the engine flywheel starter ring gear).

 

Notice: When DTC code P0338 is set, failure to replace the Crankshaft Position Sensor could result in repeated inoperative conditions of the starter or flywheel.

 

Important: Some flywheel wear is normal; broken or missing teeth and/or cracks, are not normal.
