GMC. I have a 2011 GMC Yukon LT with a 5.3 liter flex fuel.
I have a 2011 GMC Yukon LT with a 5.3 liter flex fuel. Was having trouble starting it when cold. My mechanic diagnosed it and it had 80 lbs of fuel pressure after shutting it off. He diagnosed the fuel pressure relief valve on the fuel pump as bad causing the fuel injectors to drip causing a flooding situation causing it not to start. He replaced the fuel pump with and AC delco unit from our local GM dealer. He is not sure this solved the problem. He states it still has 80 lbs of fuel pressure when shut off warm but states it goes to "normal" levels within a half an hour. He is letting me try it for a couple of weeks before paying him. Is this normal or is there something else wrong. It has started so far but I just got it back. … read more
