Hi guys,
I have a 1993 Honda del sol 1.5L
I believe i have this problem narrowed down to the coil but i would like some other opinions before i order this part.
Problem: Driving down the and car died. Power was still on but just died. Car would not start because i now have no spark from the distributer.
What i have Tested/Replaced: I replaced dist.cap and rotor. I tested the coil. Primary resistance is at 1.1 Ohms and secondary is at 13kOhm. For the icm i have 12 volts (when connected to coil) across the two wires that connect to the coil. With coil disconnected and light bulb in place of it, it turns off and on when i turn it over. This tells me that everything b4 the icm and output of icm is ok.
The recommended primary resistance is between .6 and .8 ohms were mine is 1.1 ohms. Could this be the coil or icm problem?
Also could an icm ever "kind of " work? what i mean is could the icm be switching but not be outputting enough voltage to the coil?
Let me know if i was not descriptive enough.
Thanks for any help

The ICM is just a switching device. It provide no voltage. Just a pulsing ground to operate the coil. If you can confirm power and pulsing ground coming into the coil and nothing coming out of the tower, the coil is bad. Just make sure it's not a crack in the cap or something letting the spark jump to ground.
