Default 93 SE with no spark ?????????????

I bought a 93 se 3800 that has no spark. It was hit by a deer and pushed the radiator back abit. IT looks like the coil pack made contact with the radiator but it must have sprung back because theres a couple inches between the 2 now. I unhooked all the headlights. What is a good place to start checking to find out why there is no spark??
Help appreciated

Look very carefully for damaged wires, and consider swapping in a ICM and coil packs from another 3800 from 93-2005.

The ICM is under the coil packs. Ignition Control Module. You need to check the connections and conditions of the wires first. Then go out and buy a set of factory service manuals (Ebay) or Chilton'* #28200. You're going to need it on this job.

ITS got to be your icm or the coil packs.......very easy fix, but kind of tight working space.....or maybe the wiring going to your ICM.....the connection to the ICM might be broken.....

GOT to be? What about the crank sensor or wiring, the PCM, or any other number of things including Vats?

Well because the coil pack was hit during the crash but does not appear broken.. I am hoping that is the problem.

Go to the wrecker. Get the newest one you can get. Something at least in the late 90'*.

If you do go to a junk yard to look for upgrades for stock coils on a '93 SE, which year[*] would be the most desirable?...And I've heard that MSD are the choice to make in aftermarket and to stay away from Accell: is this true?
