Melissa Maxima won't start after washing the engine bay deep cleaning

My 2004 Nissan Maxima will stay running after deep cleaning the engine bay with a pressure washer it started up and it was running really bad try to drive it down the road and it wouldn't drive it had the battery and the brake light on at the same time and all the interior lights other than that went off so I took the leaf blower and dried it underneath the hood as much as possible and it was flickering the headlights and all the inside lights except a few then they went off completely the headlights did and the car cuts off a few minutes later after trying to rev up the engine and it wouldn't do nothing when it shut off the engine try to cut it back on it won't start back up and only if you light on the dashboard inside the car is on including battery and brake it tries to turn over but won't
