74 Duster (318) ignition not working, not getting spark

If money is an issue you could check and repair sections of wire, be sure and use the correct gauge and solder/shrink wrap when you can. A wiring diagram helps also but can be intimidating if you don't know how to read one. You would basically use the diagram for example to trace and troubleshoot your ignition system, wire by wire. yes as said it is time consuming and you have to be patient. I want to also add that I have seen plenty of "melted" wires on my Mopar, and yes i did buy a new under hood harness. I could have used my old one but I tore my car down for paint and body, and figured I didn't want to get the car done only to have it catch on fire one day...Not trying to scare you .
