I needed to replace my fuel pump. I needed to empty my fuel tank. I decided to put a jumper where my fuel pump relay is to pump the fuel out a hose I connected to the pressure regulator on pump. I think I put the jumper in the wrong terminals and then I heard a strange beep sound come from nearby… possibly from the ECU? Now, when the relay is back in and I turn the key on, the fuel pump doesn’t even prime up for a couple seconds like before. I am not seeing any voltage output on any of the terminals to the Fuel Pump relay.
-Am I an idiot? Yes, I already know this answer.
-Can the ECU make a beeping noise… possibly when shorting out?
-Is it possible that I could have fried the ECU by jumping the wrong terminals to the fuel pump relay?
– If I replace the ECU, will I have to pay an unGodly amount of money to the dealer to reprogram it for my car?
