Hi all,
I have an 89 Brougham with the 307 "Y" engine. My check engine light is on and I am having trouble getting the diagnostic codes to flash from the ECM.
When I jump the two right pins on the ALDL under the dash, I get nothing, zilch, nada.
Does this mean that the ecm is bad? I just finished replacing head, intake and exhaust gaskets, all vacuum hoses, o2, coolant, oil sensor's and a new carb.
The car is running good but I cant get the stupid light to go off.
I live in CA and the smog shops will not even hook up to it if the light is on.
Any advice would be greatly appreciated.
