Hi ya red + black- green = crank blue= cam im I thinking correct hard to work out with out pulling dizzy and having original vt loom it has a haltech on it but not getting crank pulse

delcowizzid is correct, the question is what has been done to your setup, and only you can answer that!

from what i've seen of VT 304 on the driver side about halfway up the motor near the fuel rail is where the dizzy plugs into the wiring loom with a grey plug and the dizzy end of this plug at least has the red black green and blue.

if you can get hold of another dizzy you can plug it in here (even VN will work with some jumper wires) and then rotate the dizzy with the ignition on and that will tell you if you have spark or not without having to pull the dizzy.

did this a few months back with my brothers car, turns out the crank pickup sensor is faulty on his dizzy.
