cranks but no spark at coil
Well Del, whatever the "fix" it was temporary. It loses spark from coil after running a bit(5 min).
I had it running tonight. Hood up, idle up a bit and I was watching under the hood. Then it just quit.
I unplugged coil wire at dist cap, had Lori turn it over. ..no spark.
Wiggled wire in coil and saw a spark from coil tower.
Key off and r and r the wire from coil. Had Lori turn it over again and sparked from coil wire properly.
Hooked to distributor and fired right up. Lasted less than a minute then quit again.
Batt V static 12.75
Ballast resistance 1.7 ( was 0.7 before)???
Red ballast wire(unhooked)12.25V key on
Dist leads harness side 8.7 Mega Ohm resistance? ? (With everthing hooked up)Wtf?? ECU cooked?
Resistance at ECU cavities 4&5, key off everything hooked up 278 Ohms.(fsm states between 150& 900) so good.
I thought I had it beat with the new harness. It needed it anyway so no loss, but frustrating as heck as "spark check" at coil wire is hit n miss.
Very limited time with helper to test anything in crank.
MP ECU is $50 and a day away if I order one.
Thanks again Del
So what do you think was the problem?
