[Gmecm] Caprice Prom/ECM help

[David Allen]

Times two on "thanks for the chuckle."  I have actually seen this one time 
though. Buick-powered car brought in with miss, CEL light flashing, and no 
power.

The problem was.... reman ECM with missing PROM chip.  So I went on line to 
DIY-EFI.org and downloaded the correct file, erased some random chip I had 
in-hand, and made him a new chip.  Five minute repair - then the engine ran 
better but still had dead miss.  Ended up being a broken wire in the harness 
for the #3 injector that prompted them to replace the ECM. :-)
