After high pressure washing the fuel filler cap wouldn't open and the key got stuck. I could move the key but the engine wouldn't ignite. Also the mechanic removed the air suspension control unit because he suspects it to be faulty. Please tell me what could the problem be and how to fix it. What can I do to turn the car on?

When you try and turn it over the starter clicks, everything shuts off and wont start.

without the usage of a scanner

The last major service performed was at 60,000 miles.
But since that service, oil changes have been performed, drive shaft assembly replaces, coolant pipes replaced, and both fuel pumps replaced. I recently replaced the 2 front air filters as well as the pollen cabin air filter.
I wanted to know if I should replace the spark plugs, serpentine belt, thermostat, and anything else you recommend. As I said, no major service had been done except for oil and air filter changes.
Thanks so much!!

I was nstalling a new front license plate cover and needed to use longer screws. The screw went through a hose located directly behind the existing hole. What hose is it? It has to be a plastic or rubber hose as it left balck on the screw, it appears to be windshield washer fluid leaking out!
