I've tried everything to get my 2004 Discovery started after i put in a new CPS and new battery. The alarm, windows, locks, and gear shift do not respond. I've tried the key in position II for 5 minutes; the 4 locks and unlocks; holding the key in unlock position for 4 seconds; the 1515 code (but i never got the alarm to light up). I've checked the fuses and they're ok. i've unplugged the serial cable to the BCU and IDM, no go. I don't have my EKA code, but i don't think it would help because the alarm is not responding at all. the M & S and D began flashing after i ran the battery down trying to start the engine. i improperly installed the new CPS (with the spacers on first). i've reinstalled the CPS properly. Should i move to check the Neutral switch, Starter Relay, Reimmobilization coil?? I'm at my wits end, HELP PLEZ!
