After driving through flood car will crank but no start

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I’m sorry to hear you're having trouble with your Equinox. Driving through flood water that deep can definitely cause some hidden issues, even if the engine didn’t take in water directly. Since it cranks and almost starts, you may be dealing with an electrical or fuel-related issue caused by moisture. Even though the air filter was soaked and the spark plugs look dry, water could have made its way into connectors, sensors, or the fuse box. If water got into electrical connectors, it could cause short circuits. Fuel pump relays and ignition components are common trouble spots after water exposure. Although you have been letting the car dry out, it can take quite a long time for water-intruded electronics to dry. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
