Just finished installing a J&S on my MY00 RS a few hours ago but forgot to install the ground wire. I then tried to start the car but it would crank and not start. After I grounding the J&S, the leds wouldn't flash anymore, nor would my car start. I removed the J&S and reconnected my stock wiring but same problem, my car cranks but won't start! I checked the ignition 12v source wire(B135-7) that supplies the ecu with voltage while the ignition in the on postion but all I got was 0 volts? I also checked my slow blo fuses and all my other fuses but they checked good. Is there some sort of fuse that's hidden somewhere that I don't know about? My fuel pump also doesn't make any noise when I turn the ingition switch to the on position but isn't that controlled by the ecu? I also posted this in the "other" board for more feedback. I'm sure my J&S still works since I just tested it with a battery and it seems functional. I just want my car up and running again. Thanks in advance for any feedback-Rog
