You might check the control module or the hall effects crankshaft sensor in the distributor.

Definitely have a look into the CKP and CMP sensor wiring and output. Connect a multimeter each sensor (one at a time) and read the output as you turn the engine over by hand. If you are not getting any output with the key on, then there is a problem with the circuit.

Try a search for "CKP" and "CMP" for wiring diagrams and pin outs.
