I have a 2000 regal with the 3800.It will not start,dash is flashing,clicking under dash. I hooked up my snap on scanner and no communication untill i turn on the head lights. I then get the code u1040 loss of EBCM/EBTCM communication. I replaced the body control module and the dash is still flashing, no start. Please help! This car is driving me crazy!!
