Random shut off issue? Okay so I got lots of stuff done but the only ones that really matter is brand new MSD Optispark, New Waterpump, New MSD coil as well as ignition coil pigtail. It will start and run for like 10 to 20 minutes and will stall and wont start again. It just cranks. Heres the codes its running:
Code 16
Code 26
Code 36
I just replaced the canister purge valve maybe thinking it may be that. It DOES run low voltage off the alternator, maybe 11 or 12 on idle no headlights or radio in. Maybe thats cutting fuel and causing the other codes to throw? If anyone lives in Arizona and is experienced on LT1’s, ill pay you to come successfully diag it because ive been dealing with this since I bought the car

"Ignition coil pigtail"? what about the connector from the top of the distributor to the engine harness, connector about middle of the passenger side of the intake? That's what carries the low and high res signals...
16 = low resolution signal/ pulse not detected
26= EVAP Purge solenoid circuit
36= high resolution signal/ pulse not detected
16 = low resolution signal/ pulse not detected
