Help Firing Dad's Dart up Again - SOS - No Spark After Hosing Off the Dust

1...Make sure ECU is grounded.

2....Turn key to "run" Check voltage at coil +. It should be somewhere between maybe 6 and maybe 11V Not much lower, nor much higher. If it is "same as battery" it means the coil is NOT drawing current to ground through the ECU box and that is bad

3.....Leaving meter on coil+ crank the engine using the key. You should get "same as battery" when cranking, and at least 10V, more is better.

4....With key in "run" "rig" a test spark gap with SOLID CORE wire from the coil tower to a gap/ tester/ spark plug. Disconnect the distributor, take up the engine harness end, and repeatedly tap the bare connector pin to ground. A "snap" spark should occur each time you do so
