How will you adjust the injection timing of the injection pump?

What happens if the injection pump goes bad?
A faulty fuel pump will cause major performance and drivability issues with your vehicle. If your fuel to air ratio is off and the cylinders aren’t getting the fuel, then the pistons aren’t firing and your engine is struggling to move the vehicle forward. If your fuel pump is bad enough, your car simply won’t start.
What causes injector pumps to fail?
One of the major reasons for injector pump failure is an excessive buildup of deposits. There are two types of deposits – internal injector deposits and external injector deposits. External injector deposits are caused by fuel that’s not wholly burned that often builds up around the injector holes.
How do you remove an injector pump?
How to Remove a Diesel Injector Pump

- Unplug the harness running to the injector pump. Disconnect the quick-disconnect clips leading to the injector pump with your hands.
Why is timing an injection pump on an older diesel engine more important than on newer engines?
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.
