HOW Mopar starter system works.......

Whether stick or automatic, the starter relay gets the coil ground via neutral safety switch (auto) or clutch pedal switch (stick)

The ignition switch when twisted to start sends power out the yellow start wire into the engine bay to one "push on" flag terminal of the start relay. The ground end goes to the NSS or clutch switch. Try working the clutch or wiggling the shift lever while holding key ot "start."

You can take simple measurements BUT an intermittent is going to be harder

Listen CLOSE if possible during a failure Open hood "gently" if possible and listen for very light "click" of starter relay. If not, could be start relay, wiring to coil, neutral switch or lack of "start" power from key

Then try to "jumper" solenoid. Use ANY metal, quarter, keyring, screwdriver to jumper the two large bare terminals on relay--the large stud to the "square" nut/ screw connection. This puts battery power direct to starter solenoid
