1993 grand voyager help please.

I have a 1993 grand voyager 3.0 that has
no spark and no fuel pump noise after i turn the key on. And my check
engine light comes on then goes right out as I turn the key on? I
replaced the fuel pump and asd relays.
still nothing. i check for power going to the asd and fuel pump
Relays and I have power.
this all started within the last month when i would be driving at
any time the van's speedometer would all of a sudden go to 0 mph then
resume to what ever speed i would be driving all within a second.(
rebuilt trans 6 months ago and new vss in trans ) before that in the
past year i would try to start the van and no cranking of the motor.
i would have to turn the ignition key on and off sevral times to get it
to crank over (this has not happen in the last 2 months) and as today
my steering lock no longer works?

Any idea's?
Bad ignition switch?
Bad PCM?

I do have the chilton book and IM leaning toward the switch?
