no, not getting much help from this board either. glad i bought a new ford since this problem my fuel pump went (in tank) and one of the brake lines blew out,on top of the bad ball joints,leaky heater core,oil leak in remote filter line,frozen caliper,new engine, and the list goes on .no more gm for me this is the 5th in a row and i should have learned with the first one.gm cant build trucks..
