I have recently come into possession of my days 74 Duster. He drag raced the car 20+ years ago, but kept it mostly stock, just installed a B&M shifter, autometer tach, Slicks, Line lock, and electric fan/water pump. When I picked the car up, it had been sitting for 18ish years untouched. after a weekend of cleaning and other odds and ends (fresh gas, air filter, and scraping all the old racing stickers off the windows), it actually started and ran. Soon after, it stopped getting spark. I have replaced the battery, starter, starter solenoid, ignition control module, ballast resistor, distributor, coil, ignition switch (twice), And most recently replaced the wiring harness under the dash and in the engine bay. After all of this it is still not getting spark, or have power to anything past the firewall except the voltmeter. Does anyone have any suggestions?
