Ive got a recently completely restored daily driver 68 Coupe 302 4 bbl Holley with a Pertronix in the distributor. I went out to start it after work the other day and it would only turn over. Ive done several diagnostics. heres where I am at; its not a fuel issue. No spark on plug. Power on both sides of coil, I ran a jumper from flame thrower coil+ to + on Battery and it started right up..
The engine wire connection at firewall is tight.
So, Ive bought a new ignition switch(the previous one was only a few months old....) Ill replace it to see if thats the issue. What else could it be?
I was going to test the positive side of coil while cranking engine to see if it still has 12V to see if the coil is bad(not sure how else to test for a bad coil??)
Engine wire is new, if I unplug it to check for power going through from pig tail at firewall, If I check the pig tail coming out of firewall on crank/start should I be reading 12 V on just the male prong or in both the female plug holes or some other combo?
IF the ignition switch is good but theres not power on start going through to fire wall side of plug, remedies??(I seriously dont want to have to replace a dash harness...)
thanks everyone, this is my first post but Ive read lots of others posts ovr the last few years for help as I restore my mustangs
