The ignition control module (ICM) & fuel pump both get power from a fuse under the dash on passenger side. IIRC it'* fuse #6 - try pulling that fuse & check it with a meter. Sometimes it'* hard to tell their blown just by looking.
The ICM (module under coils) gets power from the pink wire on the harness. Disconnect that harness & check for 12 volts with the key on.
I'll send you some wiring diagrams while you check that fuse & wire.

Thanks. I won't be able to get back over to the house until this weekend. I am off tomorrow due to hour cut backs so maybe I can get over there then.

Could you go ahead and send the schematics to me before tomorrow so that I'll have them when I get over there? Or did you already email them to me? I am at work now and can't access my email so that is why I ask.

Diagrams were sent last night.
99% of the time no-spark is caused by:
Bad crank sensor
Bad ICM
No power or ground to ICM
Bad ICM wiring harness
