1972 Chrysler Newport custom 400ci ....Long story short Siemens shutting us down here in NY and I sold my 2018 Ram 2500 due to losing of job i have to resort to driving something in the meantime to get me to work while the doors are still open. I refuse to drive my 70' Fury so the 72' Newport was suppose to be my daily till weather and salty roads clear up.
I bought this Newport last year before covid started and it didn't run... No big deal right? Well PO stated it died on him on day and never would start after that. The even wired in a electric fuel pump and had a glovebox full of extras. I ditched the electric pump and went back to the mechanical pump and checked timing. Timing was off, reset and boom she fired and actually ran great... until the mysterious no start issue happened. The engine fired up ran for bout 5 seconds and shut off...We replaced multiple coils, ballast, points, condensers i tried two different caps and two rotors rebuilt the Holley 2210 carb also. Still no spark at the points. I went through with a multimeter and had power till i got to the dizzy.... fast forward a week... The car started and ran and i drove it home 5 miles. Then this issue happened again. So i went and bought another set of points and condenser and just replaced the condenser this time and the car fired up! I tool it for a spin which left me stranded on the side of the road about a mile from home. crank crank crank no start. I had a buddy tow me home and the damn car started back up again. Winter 2020 came and i parked the car.
Well now i need it more than ever and this ol girl just wont let me get a mile up the road till she sputters out and dies... Friday 19th i drove her all over town no issues, parked sat, went to take her out Sunday and she died 3 times within a mile and i was fortunate enough to be able to limp her home once she fired back up. Monday morning she sputtered and chugged on my way to work so i just turned around and limp her home again. After work i replaced the old mechanical fuel pump thinking maybe it was tired. Once again i went up the road and she died on me. This time she would just crank crank crank. So i sat on the side of the road for about 10 mins and she fired back up and ran her home. she sat and idled for over half hour, very responsive on the gas pedal not missing a beat.
Im lost at this point on what the issue could be. Its driving me crazy knowing this simple points ignition is giving me this much trouble. I ''believe'' i have it narrowed down to a intermittent spark problem but what would be causing it to act like this?
Im open to any suggestions
