Fitech Wiring Issues
Here's how your system should be wired.
The purple and green 2 pin connector from the Fitech throttle body should be connected to the 2 pin connector from your distributor. This connector typically has the same color wires (purple and green). Make sure the green is going to green and purple is going to purple, it makes a difference.
Red from your Fitech goes to the battery positive post.
White from the Fitech throttle body goes to the previously discussed brown and blue with white tracer wires.
The black wire from the Fitech throttle body goes to the "points trigger" input from your CDI box (typically a white wire).
BTW, Do you hear the fuel pump running followed by an injector cycle to prime the engine?
Check all of this and report back.
Good Luck
