Frgyjmpr2000,

I sense the frustration in your latest update.

I was thinking about the odd results your friend got when he used a 12V test light to probe the injectors; the car started when before it would not. Using a standard test light on the injectors is not a logical check. But I was at a loss to explain how doing so would change the symptoms as you reported. Then it dawned on me; ground through the bulb. Have him check the ground point for the injectors. If that is corroded or loose, it would explain every symptom you've reported so far.

Also, buy a "noid light" for your friend. These are available at NAPA auto parts stores for less than $20. (Tell the person at the counter you want a noid light for a Bosch fuel injection system.) With that tool he can check the injector harness for firing pulses. That is an easy check and will help lead him to the ultimate solution to this problem. Plus, he will have it in his toolbox and always think of you when he uses it. ;-)
