We all need to get codes read as quickly as possible, to prevent small problems from becoming trip-stoppers.

About the non-cranking:
1. At the top of the list goes cable connections, bad battery cells, failing starter, and the like. Make sure all related connections are good. If you have a voltmeter, check the overnight battery voltage .... should be 12.5+ volts.

2. Next comes the relay circuit ... added in '99... "start interrupt" (relay #302) and the DTR sensor on the tranny. I have had to replace a few relays on my '99. The design & quality of the relays was upgraded in later years. But on the '99, you might as well keep a few new ones on hand. Refer to your glove box manual.

While hunting the problem, you can certainly install an jumper from the small terminal on the starter (where the yellow/lt-blue wire is) to the battery area. Use insulated wire, of course. Store the wire end close to the battery. When you need, place the tranny in P, turn the key ON, and temp push the bare jumper wire end against the positive battery terminal.

Actually, I keep my "temporary" jumper in-place. I'm pretty confident I can force crank the engine no matter what.
