[quote="DeathRat"]Okay, lets start at the beginning again!
First off which ECM (Main Computer) are you using? The 92'* or 95'*? Also which Ignition Module are you using? The 92'* or 95'*? This could be your problem, forget about that BCM it'* NOT part of this equation!
My reasoning behind this is simple, The 95'* ECM & Ignition Module may require a DIFFERENT SIGNAL from the VATS system than the 92'* was programed for! There is 15 Different Resistor Codes for the VATS Keys!
It may boil down to replacing the Ignition Cylinder &/or Ignition Switch from the 95'* column!
[/b]I am using the 92 ECM, the 92'* ignition module. Thanks for the info, DeathRat. You have been very helpful Unfortunately, I am having problems locating the ignition switch etal. I purchased the engine from a salvage yard 45 miles away and he purchased it from a salvage yard in Arkansas (about 250 miles aways). Will keep plugging.
