When to reset injector pump timing for TDC?
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.
How to adjust the timing of a turbo diesel engine?
How to Adjust the Timing. Brand new cars and trucks equipped with a turbo diesel engine will generally be tuned towards a modest power input with little or no smoke but should be adjusted as the engine piles up on mileage. This is accomplished by adjusting the pump to increase the flow of fuel in the combustion chamber to produce power.
What is the DTC for a GM diesel engine?
6.5 Liter Diesel Engine equipped GM vehicles. 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.
How do you increase or decrease engine timing?
Rotate the injection pump to increase or decrease engine timing as needed. This is usually accomplished by loosening the bolts and rotating the injection pump in small increments either clockwise or counterclockwise.
How to adjust the timing of the injection pump?
How you adjust the injection timing of the injection pump also depends on the type of marine engine you have and its age. Before making any adjustments, make sure the cold start cable is in, and the camshaft drive belt has proper tension. 1. Program the ECM

How much does an injection timing system cost?
When you combine all its properties, an injection timing system can make up about 30 percent of a diesel engine’s total costs. If you’re looking to advance the timing injection of your marine devices, you want to ensure the engine makes full use of the fuel injection process.
What happens when you change the injection timing on a marine engine?
When you modify the injection timing of your marine engine, it affects many components. Advancing the system will cause diesel to inject into the cylinder sooner than usual, also causing the combustion phase to occur quicker. A timing advance shows the number of degrees before the piston reaches top dead center and ignition takes place.
