Once again, this video covers why we need to learn proper troubleshooting techniques and to not be so reliant on manufacturer "flow charts". If you think your engine computer is bad, you must watch this video! Are there more tests that can be done to prove a computer is bad? What else should you check before computer replacement?
The following is a list of other tests and how to checks that were performed in this video:
1. How to test a 24x hall effect crank sensor
2. How to test sensor wiring integrity (both opens and shorts to ground)
3. How to test a hall effect cam sensor
4. How to test computer powers and grounds.
5. What is a shared reference circuit?
6. What do you do when you have low reference or power supply voltage to a hall effect?
No Crank Diagnosis (how to troubleshoot starting system problems)
2000 Dodge Neon Case Study. This video contains theory and operation of the starting system as well as troubleshooting on the vehicle. Even though this is a vehicle specific case study, the information in this video is useful for troubleshooting all starting systems.
2000 Chevy S10 2.2L No Start (Part I)
For more on Engine Performance Diagnostics check out www.scannerdanner.com
This video is part one of a two part series. The following testing methods are shown:
How to check for spark, how to test if an engine is getting fuel when a test port is not available, how to perform a relative compression test with a picoscope, how to test if ignition timing is correct using a scope, how to test a 7x crank sensor, and how to test a hall effect cam sensor.
I also show some of variables to the relative compression/timing test and how the results at times can be misleading.
