Question about 1983 Dodge Challenger
Dodge challenger? have had this car for 10 years, no problems. I go out today to start up, turns over but won't start, No spark. Check for fuel issues no problem, getting gas to the cylinders. 318 ci. automatic, electronic ignition (no points). I replaced plug wires, distributor cap, rotor, and ballast resistor, still nothing. Could it be ignition module? Coil? How do you detemine if these are operating corectly. What else? Thanks for the help. One additional detail, just went out and checked new ballast resistor (white porcelain on firewall) and it is extremely hot, I tried to crank car over for about thirty seconds. What does that mean?
Is the rotor turning in the distributor? If so, most likely the problem is in the madnetic pickup in the distributor. If not, pull the distributor out and see if the gear on the shaft is broken. A good gear on the distributor and the distributor not turning means you need a timing chain!!!

If ballast resistor is hot, then you have either a shorted coil or a coil wire shorted to the engine block. All coil primary current flows through the resistor which limits the maximum current the coil can draw, While starting, the resistor is bypassed allowing more current to flow in the coil's primary which generates a higher voltage in the coil's secondary winding giving a hotter spark for starting only. It really sounds like you have a shorted wire since the ballast is hot when the engine isn't running. No spark, no coil current should mean no current flow through resistor.

U may need a new set of coil packs

Car not starting or turning over indicates towards multiple possibilities.
It can be issue with battery or weak battery. But if battery checks out ok, then
it can be starter issue or faulty alternator or problem with low fuel pressure
or no spark at spark plugs due to dirty spark plugs or faulty
ignition coil or injectors getting cracked or dirty and needs to be cleaned.
To confirm the problem, the basic troubleshooting is required.
