Code P1626, no start, passlock problem after LQ9 swap
Hey all,
Just swapped an LQ9 into my 2003 GMC Sierra. Had Black bear do the tune. Went to start it and got the code P1626 which is a fuel cutoff code that involves the theft deterrent system. It will crank over but won't start, I assume it's because the computer is cutting off the fuel. Any ideas what could be the cause of this? Never had this problem prior to the swap.
Thanks for any and all help!
