I'd expect a wiring or sensor issue in the case where two coils fail back/back...
Did you pull codes yet?
In the Haynes manual it states these for the DIS coil resistances;
Primary - 8.0 to 9.0 ohms
Secondary - 13.0 to 14.0 K-ohms
Primary winding to case 10 M-ohms.
The primary is measured across the primary terminal and the supply terminal at the connector.
The secondary resistance is measured between the secondary terminals (the one that the spark plug wires connect to) of each coil pack. They are measured between paired cylinders; 1/5, 2/6, and 3/4.
Coil Pack 1 (Auto store replacement)
Power to each bank is 0.7 ohm for all
Reading between each bank 1.2 ohm for all
Between coil posts for each bank 10.3k ohm on 1, 10.65k ohm on 2, 10.6k ohm on 3
Coil Pack 2 (OEM Motorcraft out of 96 Cougar LS)
Power to each bank is 0.7 ohm for all
Reading between each bank 1.2 ohm for all
Between coil posts for each bank 13.54k ohm on 1,2 13.45k ohm on 3
Primary to ground for all 4 pins is 5.4-5.8M ohm for pack 1, over 20M for pack 2
i have a printout of the http://mnharms.com/tutorials/disnostart/ and that is what tells me the coil packs are bad, plus manual charging of the coil to fire isnt producing any spark either. I know the packs are fried, So its back to the question am I just have bad luck with coil packs or could something else be frying my packs?
Maybe I am just slow today. Which part of the MNHarms test guide did the packs fail?
I had to double check that too - N17?
Replaced coilpack again, tried to fire then no spark. Retested, now crank sensor isnt working. Going to replace it tomorrow as well as the ignition module
and adding more ground straps just to be safe. Would one of the front shock/strut mounting bolts be a good location to ground to on these cars??
