new member with 74 dodge dart starter problems

The seatbelt interlock kills the starter...it won't even turn over. Plus, most were bypassed around 1975:D

Experience has been a good teacher to me about Chrysler electronic ignition, and a sudden no-spark has always been the ECU, the small metal box on the fenderwell with a 4 or 5 pin plug retained by a screw. If you drive a Mopar you need a spare anyway, so grab a new one and pop it on, I bet it starts right up. If not, you have your spare.
