fantastic, i wasn't sure if i was looking for an on or off or a variable voltage signal depending on rpm b/c i see the FPR acts as the fuel cut off for the rev limiter function.

and me in a shop without a scope... aprox. duty cycle @ idle, of about what voltage? so i can check it with a multi-meter.

pin one of DLC connector under hood goes to same terminal as pin 10 @ FPR. multi-meter results, RPM:650, Duty cycle%:37.2, 8.5mS on time and about 47.3-43.7Hz. and a rough voltage reading is from about 7-9 volts

and now the silly thing isn't broken anymore.... wish i had this info to chcek when it was acting up. starts up and runs great now, warm up was a tad rough but it runs without using a jumper. if i have a new FPR and my signal looks in spec what would be my next rabbit hole to go chase down? would worn secondary ignition components degrade that signal? IE: cap and rotor? they're pretty whipped upon visual inspection.

thank you so much.
