Even if the BAP was commanding full power to the fuel pump no matter what, you'd still not have a running engine since that requires the PCM to tell the fuel injectors to fire and the coil packs to produce a spark. No injector signal = no engine running. No ignition signal = no engine running either...
Not to mention the fact that if the BAP really didn't shut off it'd burn itself out.

Good points. No spark, no injectors, no run. Also, BAP is on a switched source for voltage.

Hey Motorhead 47.....all the years I lived in Crestview....and you were right down I-85.....damn! 
I would have hooked up with you to pick your brain on mods to my (old) 99 FRC. I now have a '09 Z06 now and am looking to do a E-force (when it comes out) on my Z..I might need to pick you brain then

It will be interesting to see Edelbrock's cooling solution for your Z06. You can't stack a Z06 oil cooler, supercharger heat exchanger, a/c condenser and then a radiator in that order and expect it all to stay cool...not going to happen....ask me how I know! One big heat soak sam-mich'!

You think one bad injector would cause dieseling? Not sure why you'd want to go with a new set of larger 60lb injectors and introduce yet another calibration variable. The 52lb injectors that come with the Edelbrock kit are the same Bosch injectors as used in the ZR1.

And, again, shutting the car off disables ignition, so even IF an injector was stuck open(it probably isn't; the car would run like crap and backfire like crazy if it was), AND a single cylinder receiving fuel was enough to keep the entire engine running (it isn't), you still wouldn't have ignition...

in days of old cars desieled due to glowing deposits in the combustion chamber lighting off fuel that was still being supplied by the carb..the ignition system has nothing to do with it.... sounds like you have injector[s]dumping fuel into cylinders...why ????? improper wiring...bad injectors...faulty ground...?????

Normal rpm although 23 degrees is a little bit much at idle. Try taking out 3-5 degrees at idle and see if that helps. FYI stock idle timing is 13 degrees I believe.
Any other "driveability" issues showing their face?...looking for clues here.

is there a way of checking to see if the coils are energized while the ing is off--injectors too? This might be an ECM hardware problem and nothing with the tune . Just a thought. sorry

I dropped the idle spark back to stock (13). It was late so I didn't get a chance to run a scan on it and check for the Dr. D. I'll check it tomorrow.

Dr. D. has left the house. Problem solved. Car shut down perfectly on my test drive.
