best thing to do would be change the sensors out with known working ones.

Maxes would not start the other day, the cam sensor plug was not pushed in all the way.

Also check the key barrel on the half cut. I dont recall 94 jdm having a switch on the barrel that has a cable that goes back to the ecu. But just have a look its a white switch with a black cable that runs out of it. It would fit a plug on harness located on the steering column. If this is not connected it will not start.
