Im having a DTC problem with my 6.5 Suburban. This is my first 6.5 and i think the truck is running fine but it wont do the KOKO relearn. The P1214 returns instantly. I have been using iCarSoft scan tool to try to figure out the timing but i dont think it works well on this truck. I only see the timing for a split secound before it reads N/A. Could the timing i see here be the actual timing(see photos)? Does anyone know where i should start? PMD? I have replaced the crank sensor but that did not change anything

 

Diagnostic Trouble Code (DTC) P1214 stored in memory after replacement ECC was installed or fuel injector pump has been replaced.
Perform Top Dead Center (TDC) Offset Procedure to ensure proper injector pump timing. Use the procedure listed below:
1. Perform anti-theft (PASSLOCK) relearn procedure first.
2. Install suitable scan tool.
3. Using the scan tool, clear any DTCs present.
4. Start engine and bring to operating temperature. Shut engine down.
5. Turn ignition switch to the ON position, engine off (not running).
6. Fully depress throttle for at least 45 seconds.
7. Turn ignition switch to the OFF position for 30 seconds.
8. Restart engine. Using scan tool, verify that TDC offset has been cleared to zero.
9. Start engine and bring to operating temperature, engine RPM less than 1500.
10. Using scan tool, verify that TDC offset is between negative .25 to negative .75. If TDC offset is within specs, relearn procedure is complete. 11. If TDC is not within specs, it will be necessary to reset the injector
pump timing. Follow the procedure outlined in the shop manual.
