laguna will turn over but wont start?

after jet washing my car this morning thought it would be a good idea to clean the engine bay. But now it wont start it turns over but no ignition the spark plugs are working as i have tested them. So defo not an electrical problem. could be the fueling because i cant get compression when i have the plugs out. could i have caught the fuel cut off switch if so how do i turn the fueling back on. its a r reg renault laguna 1.8 if you have an answer for me would be much appreiciated thanks matt.
