Jeff, try this first. Open the black box at the front of the engine
compartment toward the driver's side. In it is a threaded metal stud
with some red wires attached to it. Check for +12 volts on this stud. It
should have +12 volts at all times. There is a common failure of these
wires as they are undersized for the apparent load.

Then check for +12 volts at the ignition coil, on the terminal with the
black wires. This should have +12 whenever the key is on, especially
during cranking of the starter. Check for +12 present during both
conditions.
