Geez damn frustrating,diagnostic codes are all 12, all is good, nope, starts then something clicky turns blower on and engine electrics die, have replaced fuel pump, removed air con and blower relays to check but still hapens, help
When you say the electrics die when the blower activates does the reds switch off or does the motor simply konk out (with reds still on) ???
Have the blower motor/ a/c switched off and see if it still does it. If it runs fine with the a/c off then konks out when switche don clean out your throttle body and iac vlave with carby cleaner then reset the ecu.
