Car will not start after tuning

SonicVQ

I went back to the beginning and re-read everything and I have a few thoughts:

• If you are in the car and don't depress the clutch, press the Start button once.
• Do you hear the steering wheel unlock?
• Does the start button illuminate "Acc" ?

If the steering wheel doesn't unlock, the engine will not start or turnover.


• When troubleshooting unusual problems (like this one!) you can't assume anything. I think you should check for 12v at the "S Connector" wire at the starter and at the IPDM/ER, when someone pushes the start button.

If you want to get the engine to crank over to verify the starter, you could:
• Remove the fuel pump fuse (in IPDM/ER)
• At the starter, disconnect the small wire on the S terminal
• Use a long wire (ideally with a 5-10 amp fuse inline with it) to run from the battery positive terminal and touch the S terminal on the starter.
• Engine should crank only for as long as you are touching the S terminal with 12v.
