Problem Starting Car After Flashing ECU with FP
Posted: Mon Oct 04, 2010 1:59 am
Hello everyone. I am having some issue starting the car. I'm not sure what is happening. I have flash the ecu many times without any problem. Tonight I was out tuning my a/f. Went to a parking lot so I can upload the map to the ecu. Have done this many times.
I turned off the car, turn the key on and upload the map. Wait until it finish. After it finish I went to turn on the car and nothing. It cranks and cranks.
I glance over at the software and saw that the ECU has an X on it. I also notice the green key symbol on the gauge was blinking and blinking. Which tells me that its something to do with the immobilizer. How can that happen?
I tried to flash it back to stock but can't due to it not able to communicate with the ecu.
I checked the fuses and all seem to be okay. I pulled the negative battery and still it didn't work. I then went home and got my spare keys and tried that. Nope didn't work. I check the battery voltage and it has 12.5 volts. I even tried to put a jump on it and no go.
The one thing I notice is that when I turn the key to the on position, I can hear rapid clicks coming from the gauge area.
I have exhausted all I can think of.
What is my next step. The car is currently back in the garage after towing it home.
Can the ECU go bad? hopefully someone know something. If nothing else then Monday will be towing it to honda. Do you think they will know I flash the ECU?
