Question about Hyundai Elantra
I don't know how bad the flood is, but if its high enough your ECU may have also got damage. the ecu locate underneath the dashboard upper left side corner near the foot fuse box. if it has come in contact with the water I can assure you 99% you will need to replace it. the ECU is the brain to the car, water can also short out the ECU if one try to start the car while all the wires and connectors are still soak and wet. If you have to replace the ECU, get it from the junk yard or ebay, new from the dealer will cost you arms and a leg. In this situations you will have to narrow it down one by one, you starting off with a good idea seeing if you getting sparks and fuel. 1st I would check and see if your ECU is good and in working condition, there is no way you can bench test it at home, I don't know of any place that offer bench testing, if you find one, it will cost you about 75-100 bucks after shipping and handling. you can actually get one off ebay for 50-60 bucks used. If you think the ECU is still good, then check the cam and crank senors, one turn on the fuel pump and the other turn on the sparks. check the basic things like fuse and relays, plugs, caps, rotor and coil. for beginners, I would go down to any auto parts store and pick up Haynes auto repair book for 20 bucks, its a great bible include pictures step by step and its worth the investment. hope that help some good luck!
