No start - what to check

When my mopar doesnt start and im done checking for a neutral start...i approach it like this.
Does it turn over at all or not ...
If it doesnt but the car shows power, i simply leave the key in the run position, get out and grab the tire iron out if the trunk , pop the hood and with the tire iron...jump the starter relay thats down on the inner fender by the battery. If it turns over and starts...great. relay time.
If it doesn't...im looking at the starter, bummer if yours is an automatic, you're stuck...if 4 spd...push start and get to a a parts store.
If it turns over but doesn't start..
I her out of the car, pop the hood and pull the ballast wires off and tie them together. I used to always have a 2" piece of wire from the days of jumping obd2 end terminals for flash codes...so there is one in all the ash trays od all my vehicles.
Those are about the only ignition issues ive ever had, relay and the ballast. Ive lost an orange box to failure, once, otherwise thryve held up and the last decade in a half only used MSD igniton -coil,distributor,box. Best investment in the long run....it skips the ballast :)
Charging system on these old cars...man, that got me in my early days...dun lights, surge, smell of hot wires late at night driving down the 99 lights going brighter...
The grounds just sucked, the regulators...suck too, they arent quality and verybsensitive to the slightest resistance in chassis ground. I still to this day have to loosen , clean, and retighten the voltage regulator ever so many month's due to living by the ocean partially and then just by pure design. You litterally need a ground wire that spans the entire system , batt - ,reg, alt, inst cluster. Just piggy backin on each..lol
