No that diode just protects most every thing if you hook up the battery backwards.
If it was open (BAD) then neither the PCM Power Relay or the Fuel pump relay would be picked when the key is turned on.
Did you plug the STI wire into the code reader also?
If so then you either have a bad EEC self-test/STI plug or no power to the PCM Computer or no ground to the PCM Computer or a bad PCM Computer.

Also when I was under the column , when I was trying to find out where and which was the hot wire going into the white box , I hooked my multi tester to two different thicker yellow cables one at a time and then the other negative lead to the metal bracket that the E brake is mounted to , to get a good ground , One yellow wire was in the switch to pick up a hot connect when switch was activated I'm assuming , so it showed nothing on the volt meter and the other yellow wire did show a constant 12 volts or more , in just checking those wire with them grounded right there on that bracket , could that have blown my ecm or pcm , or both ...? please man help me , Ill pay you for your time,,,!!

All three large yellow wire are the power source for the Ignition switch.
One yellow wire is powered by fuse "P".
One yellow wire is powered by fuse "N".
One yellow wire is powered by fuse "J".
Your Black ICM (ignition control module) very seldom goes bad but it just controls the spark and has nothing to do with fuel system.
A loading test light might be a better tool to use when working with these circuits.
