i have a 94 bonniville that just recently died on me while i was driven i changed the cranksensor, control module, coil packs, spark plugs and wires, fuel pump and the mass air flow sensor the car turns over but there is no fire comming out of coils but there is fire going through all of my wires cause i tested them myself and i checked all the fuses under the driver and passenger dash and under the hood and all the fuses were good i also had someone to test the obd1 and it isnt giving no reading 4 the problem.

3 things an engine needs:
air
fuel
spark

it'* not getting one of those.

In 94 and 95 it is very common for the pcm to go bad. Usually they cause poor running and a lot of tail chasing. If you have confirmed all of the things you mention, it would be a good consideration.

The ecu is located up under dash in the passengerside footwell. When you swap the ecu, change out the eprom chip from under the access panel of the ecu. That contains the programming for your trans, engine etc.
