Just bought a new ECU Same old code comes up F9C4 also two new codes F9A3 and F4E3 I would like to know what the last two codes mean. I thought the reason for buying the new unit was because the old one was bad as the code F9C4 indicated ,not to have two new codes appear and the machine now instead of just starting hard will not start at all . Does anyone have any info on this??
