Hi Mark

Diesel diagnostics can be a bit daunting especially with non starts and certain loss of power situations

What would be good, and I am not sure if there are any already out there, is to have someone who works or mentors in diesel systems to create some Flow Charts (from real life/workshop experience) for different scenarios as mentioned above. The biggest problem is knowing where to start, as we know codes help but that's only the beginning

Many techs sometimes start their diagnostic process to far down the line while ignoring the basics. Some logical flow charts related to the faults would be excellent. I see Delphi has a tool now for analysing Diesel fuel to see if it is contaminated in any way with say petrol, perhaps this should be a first step tool now when dealing with diesel faults (think you can see where I am coming from)

So come on Keith, Frank and James how about some decent system flow charts for correct diagnostic procedure in bulletins or books, I would be willing to pay for them

I am not talking "Silver Bullet" bulletins, but to give diagnostic guidance and thought process to your problem (in the right order), will also help you learn and understand the systems as you go

And if you are still having problems, then post on UKAT , but we will at least know you have covered the basics
