Can you return everything to stock( replace the solenoid) and then pull fuse 42 for an hour.
(Or, disconnect BOTH battery cables and then touch the two cables together)

This will wipe the entire memory and return the car to the way it was built.

Leave the gmpp tune for now.

Let me know how that goes.

Before I deleted the solenoid, that was done multiple times.

I did finally get a P2188 code on my drive home yesterday. I've got to pick up some vacuum tubing to put the solenoid back to stock, then drop it off at CarMax with my extended warranty. Stay Tuned.

p2188 is more then likely your HPFP.....  Tell them to check the oil for raw gas.

Both fuel pumps replaced by CarMax. Been driving it a week, no codes, no limp mode.
