Blue,

If you want to learn and understand how CIS troubleshooting is done correctly, stick to this forum. There are plenty of help available. But first, get a decent set of CIS pressure gauge kit. I recommend getting a S&G tool brand. The basic model is more than sufficient for your needs.

This is a mandatory tool for troubleshooting any fuel injection system. If you don’t have one, you are just wasting your time trying to diagnose a fuel injection problem. With your pressure gauge kit, you will be able to check your control (cold & warm), system, and residual fuel pressures. And subsequently be able to evaluate your WUR and FD yourself.

Finding a good mechanic that knows and understands CIS is a dying breed. They are still available but getting fewer as time goes by. BTW, the mechanic who worked on your car is not very familiar with CIS based from your information #3 & #4. Good luck.
