    2007 GMC Denali stalls after towing

    IMO trans heat combined with catalytic converter heat would contribute to vapor lock, my trans temp would go 3/4 of the way towing not necessarily over heating the trans, but since the upgrade trans temps don’t go past half and i don’t stall anymore Sent from my iPhone using Tapatalk

    2007 GMC Denali stalls after towing

    I don’t believe the OPS controls the fuel pump but simple enough unplug the sensor and see if the truck runs, I’ve done a few of these sensors and the trucks were always able to drive to me, and like you said there was a code stored related to its failure Sent from my iPhone using Tapatalk
