91 Taurus Won't Start ... No Spark

Got a 91 Taurus. It cranks but won't start. No spark coming from coil. Coil is good. Also noticed fuel pump does not prime when ignition turned on. Can anyone help point me to what the problem might be?

Blown fuse? Have you checked them yet?

Yes, Checked the fuses. They're good.

Also checked the inertia switch (thought that could have something to do with the fuel pump not engaging) but it wasn't tripped.

Probably your ignition switch since this controls the fuel pump and everything else.

There is an ignition module bolted to the side of the distributor, they can fail, not an easy way to test it. replace that first.

Still haven't had any luck. Still no spark. Here are the parts I know are working properly:
Distributor
Stator
Ignition Module
Coil
Fuses/Fusable Links
EEC Module
Resistor
Wire from coil to distributor
There appears to be power to the coil and ignition modules.

I haven't replaced the ignition switch. I'm hoping that isn't it. I did one of those once and it turned into a nightmare. Can anyone else offer any other ideas before I try to tackle the ignition switch?

Thanks ...

Also, is there a alarm factory or aftermarket installed on this vehicle?

would check the ground wires going to the integrated relay box usually the small ground wires coming off the negative cable is what controls the relay box they can be corroded at the connector also might check the fusible links that go to the same relay box mounted on the radiater near the battery a wiring diagram would help to test the wiring.
