u1255

Good Evening Everyone, First post and new member, I own a 2003 Lesabre Custom with 133K miles on it. Been garage kept for the past 4 years until i got it back running last year. Replaced The fuel pump, upper and lower intake gaskets, coolant elbows back in 2021. It sat for a bit then...

My 1998 Regal GS just died yesterday. I towed it to AAMCO and he said it is throwing a U1255 code which is where the ECM and PCM communication has been lost. Does anyone know how I can fix this myself or how long it will take? I don't know if it's worth putting the $ into it at the shop. :sad...
