1KZ-TE Injection Pump Timing | Step By Step Tutorial | No Specialty Tools Required (4K)

Summary

In this video, the narrator explains how to time the 1KZ fuel pump without the need for specialized tools, debunking common misconceptions about what’s necessary for the task. Demonstrating with a spare engine, the process involves aligning timing marks on the pump and adjusting it by loosening bolts, ensuring accurate fuel pump timing. The narrator also shares troubleshooting tips for timing-related error codes, such as 41 and 14, and explains how to use the engine's diagnostic mode to identify issues. Overall, the video provides a straightforward, cost-effective method for setting the timing on a 1KZ fuel pump.

Takeaways

• 😀 Don't buy specialty tools for timing the 1KZ fuel pump; you can manage without them.
• 😀 The 1KZ fuel pump can be timed without the need for complex tools, such as dial indicators or Bosch-specific socket sets.
• 😀 The timing of the fuel pump is critical, and it involves aligning a mark on the pump with a corresponding mark on the timing gear cover.
• 😀 To time the pump correctly, loosen the bolts on the pump, clock it to align the marks, and then tighten the bolts again.
• 😀 Ensure the timing is correct when the engine is rebuilt or when reinstalling the pump, as incorrect timing can cause issues like error codes.
• 😀 If the engine is out of the car, it's easier to work on, but timing the pump in the car can be tricky due to tight spaces.
• 😀 When working on a Hilux, you might need to remove the front wheel and move the power steering line for better access to the fuel pump area.
• 😀 Error codes like 41 and 14 may indicate timing issues, which can be solved by correctly timing the fuel pump.
• 😀 To diagnose engine problems using error codes, you can put the engine in diagnostic mode using a paper clip to bridge TC and E1 pins.
• 😀 The diagnostic mode will trigger blinking lights to indicate error codes, and researching those codes can help troubleshoot the issue.
• 😀 Proper fuel pump timing can fix symptoms like engine light activation at low engine speeds, which often points to timing problems.

Q & A

What is the main focus of the video?

The main focus of the video is to demonstrate how to time a 1KZ fuel pump without the need for specialty tools, dispelling common misconceptions about necessary equipment for the process.

Why does the presenter advise against buying specialty tools for timing the 1KZ fuel pump?

The presenter advises against buying specialty tools because they are unnecessary if the pump isn't being disassembled, and the timing can be done without them using simpler methods.

What is the importance of the mark on the fuel pump?

The mark on the fuel pump is crucial for aligning the pump correctly with the timing gear cover, ensuring proper timing of the fuel pump.

How do you time the 1KZ fuel pump according to the video?

To time the 1KZ fuel pump, you loosen the bolts on the pump, align the mark on the pump with a corresponding mark on the timing gear cover, then tighten the bolts to secure the position.

What does the presenter mean by 'clocking' the fuel pump?

'Clocking' the fuel pump refers to adjusting its position to align the marks on the pump and timing gear cover, which is necessary for proper pump timing.

What tools did the presenter purchase but later found unnecessary?

The presenter purchased a generic dial indicator set and a socket set for Bosch diesel pumps, both of which turned out to be unnecessary for timing the 1KZ fuel pump.

What is the benefit of having the engine out of the car when timing the fuel pump?

Having the engine out of the car makes it easier to access the difficult nuts and bolts, especially the one located at the back of the fuel pump.

What problem did the presenter encounter when initially rebuilding the engine?

The presenter initially clocked the fuel pump incorrectly, which caused error code 14 or 41, related to the timing of the fuel pump.

How did the presenter diagnose the error code and its cause?

The presenter diagnosed the error code by using the diagnostic mode, triggered by bridging the TC and E1 pins. After some troubleshooting, it was determined that error code 41 was related to a timing issue, which was resolved by correctly timing the pump.

What is the process for putting the engine into diagnostic mode?

To put the engine into diagnostic mode, the TC and E1 pins must be bridged using a wire or paper clip, which will make the engine light blink in a specific pattern corresponding to the error code.
