Please do not flame me, I do not have a scanmaster yet. This is whats happening: Car starts and runs fine and strong, I take it for a few quick trips around the block to break in the new motor, come back, turn it off and I do this a few times. However after several trips and the motor heats up, I turn it off and try to re start it, the starter will not do anything, no click, no nothing. Everything else is working the way it should, fuel pump is working, lights, horn, everything. When I get out the battery charger with the 200 amp car start and hook it up, she kicks right over. I have redone the grounds thinking it might be that, no luck. It also has died when pulling into the driveway after these no starts happen. but as soon as I hit it with that 200 amp start, it fires right up. It is a new high torque starter, i changed the coil pack last night, no go. I am thinking it may be the alternator but that was new too. I am going to pull the new battery and the alternator and have them checked out. Any other suggestions are welcome! when she is running, she runs good, but I am afraid to go anywhere and turn her off!
