Will report back once I get home and do it. Praying to hear that annoying little hum again.

Yes, as long as you don't short the wire out while doing it. That is what the prime connector is for. They did that at the factory to prime the fuel system for the first time.

I can only give you a hint of what to look for. Everything I have software wise is TunerproRT, and it is free on the net. It allows recording and modifying files in the programming, all in English. Everything is ancient in computer terms. The laptop/notebook computer I use to make recordings is an old Gateway, running windows 95 or 97, appropriate for the era. The reason I still use it is the cable I made to connect to the ALDL connects to a serial/printer port which pretty much obsolete today. The instructions for making the cable are on the net but probably are now available purchased that connects via USB. The other reason for the serial port is the hardware for the chip is a Pocket Programmer which connects to the same port and was made by Intronics. I also have a UV chip eraser, made by Holliday Electronics. Both of the hardware items are more than two decades old which I acquired from a friend that planned to tune his Grand National which has been sitting up on jackstands with the engine out since around the turn of the century. There are a couple of other tuning sites for these vintage vehicles, Tuner Cat and Gearhead EFI, but for the actual work I have done, I use TunerProRT Despite all the old tech, the most help and guidance I have received is from Ryan of GM Tuners. Originally he made chips for me and modified them based on my crude recordings from an Auto XRay. He has been a wealth of information even after I started doing things on my own and I owe him a lot. The programming you will modify, called .bins, are generally available on the sites previous listed. You also need the sort of decoder file, called an .xdf, to be able to read the .bin, also on the above sites. Today, Moates.net has all the hardware you will need. I have an Ostrich 2.0 which connects my newer laptop, running a current version of Tuner Pro, directly to the ECM via the chip socket. You can run the engine via the laptop and make changes in real time, save the file and then burn a new chip

I don't doubt he is a good mechanic, but are you sure he is accessing the codes correctly? Sometimes people not familiar with the Buick Reatta get confused on how to check codes. Read this and you might want him to read it as well unless you sure he is checking codes correctly CRT diagnostics telling me I have problems?
