Problem solved

Crank angle sensor is very heat sensitive. They get their signal off the crankshaft pulley so it will be located somewhere around the CS pulley. I don't know if they are go/no go or if it could produce your symptoms, but without a proper signal from the CKS the PCM won't signal the coil pack to fire. I think all you can do is test the resistance at certain temps and compare to spec.

It was definitely not the CKS. But.... it was very close too. I tried to cool down the CKS with ice spray. It worked in the beginning, but then nothing at all worked. My guess was that the spray got into the distributor where the CKS is located on 94 Rangers. I checked the plug and that's where the problem was. The spray went inside the plug that has a gasket, but that one was torn causing the heat problems in the beginning. I straightened it and since then no more worries.

Thanks to all for the answers and the concern.
