HI THANKS FOR THE INFO, ARE THEY SENSORS OR RELAYS.
I GOT THE KEYS & ALARMS WORKING BUT THE ENGINE JUST DIES SOMETIME & THEN WILL RESTART AFTER 10 MINS OR SO OR WIT A JUMP START

Sorry your original post got missed :cry:

You may have a CPS faulty as alarms do not normally fail like this.

Your battery does not sound too good if you have to jump start
