Cranks but no start
97 C5 Been running fine,Starting fine.Went for a ride today, Went to do it yourself car wash,Shut the car off,Waited for the guy to finish washing his car,Started my car up drove in the bay,Washed my car.DID NOT WASH ENGINE BAY,But I did open the hood and used the blower to clean any water off that got in there,Went to start car,just cranks,No start.No codes.Took ignition switch apart,Cleaned that,I have spark,I have 12v to the injector plugs,I have fuel pressure,Fuel pump runs,Changed injectors,Still no start.The spark plugs are not wet,What would cause the inj. not to fire?What should I look for?...................Paul

Check the fuel pump relay in the engine bay, mine was bad and my car would crank and not fire and then at other times the engine would crank and fire right up.

Relay is fine,I can hear the fuel pump come on when I turn the key,And when I took the inj. out the fuel rails were full of fuel.There's no corrosion around the pcm.For some reason the inj. are not firing.

I just read some where if you cranking the car over and the tach is not moving it could be the crankshaft sensor.Could that be correct.
