I have a 1997 350 gas burner. It was running great then all of a sudden it will not start. It is electrical not a gas issue cause I tried to start with ether and doesn't even try to start. I have replaced coil, electrical control module and distributor. Still nothing. Someone told me it must be a wire but ive followed wiring and cant find a problem. Is there anything I'm missing?

 

I believe your vehicle has coil on plug ignition which could mean there is possibly no power to the coils. At this point you might check the fuses, both under the dash and under the hood.

If it is a blown fuse , there could be a shorted coil problem.

Some vehicles also have a dist ign system and if you replaced "the" coil , your vehicle has a dist.
What you might try is to confirm there is power going to one of the coil primary terminals with the key in the on position. That power comes from the ign sw. When the engine is cranked over the other primary coil terminal should blink which allows the spark to be created. It is always a good move to check all the fuses .
