Malfunction light problems...

[protour_chevelle]

I hooked up a LED for my malfunction light... Ran the proper resistor for it aswell. It worked for a good month(just turning the key to the on position) then today it stopped working... I took the LED off to make sure that it still works and it does. The only changes I made today was weld a piece on the firewall, and added a ground strap from the engine to frame along with hooking up all of the other harness grounds.... I checked to make sure if I caught any wires with the heat(welder) or grinding(with the grinder... All off the wires for the malfunction light are in perfect working order....

What else can I add. I turned the key on and put a tester on the wire coming off of the ECU, the wire on the factory harness, not the length I had to add on and I get nothing.

Also with the Drive By wire TB.... When the key is on the "On" position but the engine isn't running the TB should not move when the pedal is moved correct?

Thoughts?
