Your big two would prolly be either the crank sensor or the Cam sensor. Does the upshift light come on while cranking? If so its your crank. That was my exact problem. Crank sensor is about 55 bucks and the cam is somewhere around 30.

does anyone know the error codes for the crank and cam sensors?

Cam sensor doesn't throw a code.

Crank sensor doesn't throw a specific code, but the SPOUT missing might show up in a code description.. its a direct result of a failed crank sensor, at least MOST of the time. Its possible for the harmonic balancer to be out of position also.

FWIW, your problem sounds like the cam sensor. I'm about 90% sure of it from the description. Be thankful, its the easier of the 2 to replace.
