I'll throw myself at you collective mecies and see what happens. I got the 2004 ready for a map upgrade today but I pulled the wrong fuse, it wasn't the light fuse, it seemed to power the OBD cable because the light went out. Amyhoo. found the right fuse, connected to Tuneecu on my phone just fine, started the upload then lost connection, now it won't connect to Tuneecu or spin up on the started button (and I'm assuming the pump should make a sound too, which it doesn't). Battery is at 12.8v so pretty ****ed good. Would a suddent ignition switch failure disconnect the ECU, fuel pump and starter?

need more info
does gauges sweep?
with a 12 volt test light test all fuses on both sides. you have two fuses at the rear that are spares and will not check.
Would a sudden ignition switch failure disconnect the ECU, fuel pump and starter? (yes)
so would a blown fuse.
will brake light and horn work?
did you put the light fuse back in? that will cause your problems.

Hi, yes gauges sweep, lights on gauges all on. I have visually checked all the fuses but will run a meter over them tomorrow. Rear sidelight works, didn't check the brake or horn, again I'll do this tomorrow. I did put the light fuse back in. Thank you by the way, as long as I didn't fry the ECU somehow, I'm sure this won't be too hard to sort.

the ecu's are very good and will take most screw ups
it is easier to find the problem when it is acting up.

You may have to complet a failed from download ,where it installs a standard tune into the ECU and then you can change it to what ever you like.

Ok, all fuses check out fine on the meter. Tuneecu seemed to be hunting for Bluetooth devices yesterday, I'll try again today with the BT off on the phone.
