My 1991 lincoln want start

hi, any help would be appreciated,

i have a 1991 lincoln town car executive series. car has been setting for about month because i am restoring the outside with some cosmedics fixing. the car was starting great everytime i went out to start it before i took my pressure washer and some engine cleaner and cleand the old oil from off my engine. and i also changed out the valve cover gaskets. did something get wet that is keeping the car from starting? like i daid befor the car was starting great befor i cleaned the engine…any help would be great…thanks

Crank, but no run? Check to see i you nave spark. If no spark, start pulling off the ignition connectors and drying them out. You can get into trouble with a garden hose on an engine cleaning project so I am not surprised you have trouble after pressure washing.
