Default No spark on a 1996 SL2

Hello everybody,

I am looking for some help on a 1996 SL2 that is not getting spark. I have replaced the crank sensor, starter, the coil packs are new and all fuses appear to be good. I am still getting no spark. I tested the plastic fitting below the coil packs and I am getting power to there but not to the coils. The engine cranks and the battery is new in '09. Any ideas on what may be the problem?

REWARD EXCELLENCE!

Usually the cps fails first but a few ignition control modules fail with the same effect - a no spark condition. The icm is what the two coils plugs into. If you can, buy a used set of coils and icm from a junk yard as they're cheaper and work just as well as new ones costing more.

...
*The CPS is the heart of the entire EFI system. No cps = dead EFI system*
*There's more to a/c than just a few cans of refrigerant*
*There's more to brakes than just replacing parts*

^^^^^ +1; buy at the pick & pull junkyard, put the coils on the module and bring it to the office as one assembly, say it's "a coil", and you'll probably only be charged a one-part price.

Is there any way to test the ICM so I don't waste anymore money. It looks like the ICM is around $300
Considering I only paid $300 for the car I am a little hesitant to put anymore money into this thing.

Well, you have a choice to try a junk yard for used parts at very low cost, shop ebay for the same, check the icm (maybe) at Autozone(?) or buy a new expensive replacement.

Wrecking yard. ICM's don't go bad very often so it's a good way to go. That said make wure that you have the crank sensor in the block all the way and the connector in the sensor all the way.
When you say that the fuses all appear to be good did you make sure with a test light? Power on both sides of the fuses?

I found an ICM for 25 bucks so I will be putting that in soon. I'll let you know as soon as I find out if that is the culprit. Would a bad battery connection cause no spark? I didn't test the fuses but they all look like they should work. The EIS and both PCM fuses have been swapped out for new ones just for S's & G's. Thanks for the replies so far
