Troubleshooting a Bosch VE injection pump and a P7100 pump requires a systematic approach. Here’s a step-by-step guide to help you with the process.

### General Preparation
1. **Safety First**: Always ensure that the vehicle is in a safe position, engine is off, and you have the necessary tools and protective equipment.
2. **Check the Basics**: Before diving into the pump, make sure the fuel tank has enough clean fuel, and check for proper electrical connections to the pump.

### Troubleshooting Steps for Bosch VE Injection Pump

1. **Visual Inspection**: Examine the pump for visible signs of wear, cracks, or leaks. Look for leaks in the fuel lines leading to and from the pump.

2. **Fuel Supply Check**:
– Ensure there is adequate fuel supply to the pump. Remove the inlet line and check for fuel flow when the ignition is turned on.
– Check for clogged fuel filters that could impede flow.

3. **Pressure Testing**:
– Use a fuel pressure gauge to check the pressure at the supply line. Follow the manufacturer’s specification for correct pressure readings.

4. **Timing Adjustment**:
– Confirm that the pump timing is set correctly. Incorrect timing can lead to poor engine performance or starting issues. Refer to the manual for the specific timing marks.

5. **Governor Service**:
