Hello, are there any codes? Your obd1, you can check codes yourself.

If it crank good but won't start, have a helper crank it, while you check for spark at the plugs and injector pulse. How's the fuel pressure?

If you have an injector pulse, that should tell you if there is an rpm signal, I can't tell you the crank sensor is faulty without checking the circuits. Do you have B+ and ground at the ignition module?
