Replace the coolant temp sensor, the one next to the thermostat housing.
Put it in gear and try to start the car. Then put it in either park or neutral and try to start it.Cranks in gear or doesn't crank in park/neutral: switch is bad.Doesn't crank in gear but cranks in park/neutral: switch is good.

No crank sensor on a 1990, only the pickup plate (cam sensor) in the distributor. how about a 1991?

rpm went to zero cranks but wont start
it does not have a crank position sensor. it uses the ignition control module as a crank sensor. it is in the distributor cap
fuel pump in the gas tank
My 1990 Lumina 3.1 had the same problem and it was caused by the crank sensor.
