ok, the red light comes up for 2 reasons.

1. low coolant in the surge tank. make sure the level is good.

2. oil pressure too low. with low oil pressure, it will turn on the red light

light is on with key off. engine cranks, but will not run.

with the red light on, it will not start

I would check the ignition switch.

I would inspect the harness for the ecm closely as well for any damaged wiring.

the ecm may also be the failure in this
