I have a 08 Tahoe z71. I had a 09 block rebuilt. New pistons, rings, all bottom end bearings, btr stage 1 cam, new lifters, new refurbished heads. DOD/AFM delete. Put all back together. Got it started with the old galley cover connected, ran for about 45 sec to a minute then shut off on its own and won’t start again. Threw a code for crank sensor. I’ve replaced both the cam and crank sensors. Still nothing. Won’t start again. I’ve checked all my grounds, I have 60lbs at the rail. Cranks but won’t start. I also ran a separate ground to the injector harness and nothing. Any help would be great. Thanks in advance.
