Newbie here, please help. I am having multiple electrical problems with my 04 Avalanche Z66. First, I can not get gas to pump into the tank right, takes more than 10 minutes to fill up. Second, have replaced the ABS motor and valve assemble and continue to have "service brake system" code continually. Third, now my Traction Control light is on signaling my "TC" is turned off. About ready to dynamite this truck. Please Help!!!

 

a clogged evap vent path, vent solenoid stuck closed or clogged canister can cause all cause slow tank filling. air must vent out of the tank as fuel is pumped in.

have the abs codes cleared. test drive and post what dtc reset. traction control will be disabled when an abs system fault is present.

 

Have already had canister and solenoid replaced. Will check the abs codes. Thx
