OBD2 error code P0601 memory module issue. If i disconnect/ reconnect it cranks starts runs, never stalls or dies until you turn key off. To restart you have to repeat the process. tonight I pulled the fuses for the PCM B, CRANK, ETC/ECM, ING E and the DLR turned key to start position twice turned off waited 5 mins replaced the fuses it cranked. I did pull the starter relay and jumped 30 - 86 cranked but no start, swapped relay no crank. Batteries are good even under load. I've checked/tighten the grounds I could find cleaned battery lugs/bolts and connections still issue of no crank. I tested the 3 wire connect on the ignition/key it was fine. Oh by the way this 2005 GMC 2500HD DURAMAX 6.6L TURBO.
