ENGINE CRANKS BUT WILL NOT START

GENERAL
If the starter will not crank engine, the problem is not ignition
related. See Section 5-Electric Starter.
IMPORTANT NOTE
The engine may be started and run when the trouble
codes are received using a jumper wire on Pins 1 and 2
of the data link connector. However, if the jumper wire is
removed with the engine running, the check engine lamp
will continue to flash trouble codes. To stop check engine
lamp from flashing codes, turn engine stop switch OFF.
