1999 Hyundai Accent

My 1999 Hyundai Accent won't start. When I turn the key there is no click , the engine doesn't even try to turn over, there's just nothing. The only thing that happens is that my inside lights go on and radio etc. So i thought it was the starter so i changed it. When i tried starting it nothing happen again beside the lights going on in the car etc. So i thought it was the battery so i got a new battery and put that in. The car started once then died out. Now its back to normal. I Try to start the car and there is no click, there's just nothing besides the lights illuminating inside the car etc. what could be the problem?? Already Tried: changing battery and starter Answer: There could be a couple of issues. Your vehicle is equipped with a starter relay (located in the engine compartment relay panel), you can try to replace that. Sometimes there other relays on-board that you can use because they are the same as.Another concern that can't be over looked are the negative and positive battery cable condition. If there is too much resistance in the cables (corrosion) the current cannot flow to the starter. There is a test called a voltage drop test. Let me know if you are interested in performing it. If not, have a professional technician do the test. Engine No Start Diagnostics
