Yea, I live in Bolivar, Ohio, and for everyone who doesn't know what's going on right now, the entire area is flooded to record levels. Well, anyways, I was on my way to a date when I came across this road covered with water, with little time to get to my destination I decided to try to cross the flooded road, and of course I end up putting my car into water which was knee deep. I towed the car back to my house and dried it out. Unfortunately I discovered that the fuel pump will not work. I pulled the tank and checked the wires and confirmed that there's no juice flowing to the fuel pump. Just to make sure though I bought a new fuel pump and it does not work as well. I replaced the "master relay" fuse underneath the dash of my car, and still the fuel pump doesn't work. I've checked all the fuses and have been unable to find anything wrong. What's interesting is that my fuel gauge does work, because I emptied the gas tank and it shows on the fuel gauge. The car will turn over when I spray ether into the air intake, so I know that the engine works, but for the life of me I can't figure out why the fuel pump won't. If anyone has any suggestions they'd be much appreciated. Thanks.

 

Well the gas gauge operates via the fuel sending unit in the tank. Not the fuel pump.

 

Did u check for power at the fuel pump?
Did you check for power at the Main relay?
I would check the wiring harness from the fuel pump to the engine compartment - or wherever it runs. In my 99 Accord the fuel pump wiring runs under the car in a "cat trac" wireway. The force of the water under your car may have stessed the wire and broke it somewhere.
Check for power and continuity. Probably just a broken wire.

 

this happened to my accord but I didn't run it through the water and I checked everything new fuel pump, main relay, all wires and come to find out it was a blown fuse

 

Most likely the ECU located in the passenger footwell got wet and shorted out.
Pull out the ECU/TCM bracket and remove the ECU (the one on the left).
Try opening it up and letting it air dry. Also, I recommend changing the oil when you get the car running. Often a bad ECU will cause the injectors to stay open and dump a whole bunch of fuel into the engine.
