1998 Chevy Blazer no start in rain or damp weather

Just replaced crank position sensor this morning with a new one. Started the engine ran fine. I hose down the engine and now it will not start again. So the run down is new cap, rotor, cam position sensor, crank position sensor, wires, plugs. It has spark, but I can not be sure if the spark is at the right timing. Once is a while it will back fire or kick. The engine will abruptly halt as I am turning it over, as if the plug is firing out of time and fighting the starter. I did spray starting fluid in the intake and it does not help. I’ll check on the Passlock system.
