Common Failure Symptoms
Before replacing, confirm the fault. Signs that point to a failing BQ2000-BH injection pump include:
- Hard starting, especially cold starts
- Unstable idle and engine shake
- Loss of power and black smoke under load
- Rising fuel consumption from worn plungers and low delivery
- Delivery-valve leakage causing uneven running
These symptoms can also arise from related components, so verify the fuel pressure and electrical supply before fitting a new unit.
Installation Notes
Set static spill timing: rotate to TDC compression on cylinder 1 and align the pump drive-gear timing marks to the flywheel pointer. Match the exact ordering code (4QT72Z vs 4QT80R9) and engine (490BPG). Prime with clean diesel, torque the delivery-valve holders evenly, and set the governor oil before first crank.
