The engine stoped when I was driving and wouldn’t start up again. The car was driving just fine, then suddenly started shaking and died. The car was towed home.

The engine gets fuel and spark. I replaced the Crankshaft Position sensor / over protection relay / cap & rotor and spark plugs. The compressor is 175 lb on all cylinders. I sprayed some start fluid and nothing happens. I am at a loss for any other ideas. Could the map relay be the problem?

I'd appreciate any suggestions or advice.

Thanks!
