Do you have 12 volts on the coil + when the key is in the on position?

Get a $12 Haynes manual from almost any parts store. Not a Chilton's.

does the starter turn the engine over as fast as normal, or is it slow. If the battery has poor AMPS, the VOLTS will read fine, but it might not have enough juice for both systems. your solenoid could be acting up too.

it turns over normal to me. your talking about that red and blue wire comeing from the solenoid to the modulator right yeah that has 12v there too. as far as amps I dont' know it is kind of a challange to hook um a volt ohm meter in serise with the circuit. and I know the battery is good I had it checked

Don't try to put any meter in series with the starter. If it didn't explode or catch fire, it'd burn the fuse instantly. The meters for testing over 30A are inductive - they clamp around the wire they're measuring.

There are a few other active threads about cranking problems, so look around.

I wasnt' going to put it there I was talking about between the modulator and the solenoid. I'm an electrician I know about that kinda stuff. but thanks for the tip I'll check out other places.
