Fellow Cruzers seeking some help. My 2012 LT has some start stumbles on start up after its been sitting for a while ONLY. I replaced plugs, coil pack, and injectors. Runs great. No codes. I checked fuel pressure when on and its at 60psi. On start up its at 0! Any ideas?? fuelpump? Fuel pressure sensor? I dont think these cars have fuel pressure regulator?? IM going bananas trying to nail this down. Thanks
