Whats the voltage going into the coil?

Electicity 101
If a known voltage (12VDC) is applied to a load (the coil) and the load does not function, then the load is bad.

Don't remember exact figure, but it was above the the specs in Hayes manual, that's why we replaced the coil.

Put a spark plug in the coil wire and ground the spark plug. Crank the motor and check for spark.

Based on your description and the fact that you've already replace the coil it's probably going to be the Crank Position Sensor.

Bets anyone?

Test it

Thanks everybody! I'm going to look into that today, only thing that stinks is I'm finding them to cost about $100+ so it may take till payday to replace and that doesn't come till Friday. Any suggestions on how to test? Maybe just a continuity test with volt meter? Or is there something else I can do to check it?

Don't replace it most common get you by easy fix is just unplug it blow it out and plug it back in. Should fire right up.
