OVS Turbo kit M1000 won't start with pure logic

So, one of the last kinks i have to work out of this turbo project, I have my turbo installed, and i tried starting it with the pure logic box hooked up, and it won't fire at all. If i put a little gas in the cylinders it will start up and die from lack of fuel. I have the injectors hooked up to the correct sides of the pure logic box, with yellow to yellow and green to green, yellow on mag side, green on pto side. I read some posts about sometimes having to switch around the wires inside the plug for the injectors for it to work, but I thought this was on M7's. Could that be the case on my sled? It WILL start without the pure logic box hooked up, with the injectors hooked up in stock form. If I have to switch the wires around, what type of tool do I use to get them out of the plug to swap them?
 
Do you have a good ground, if you hook it up stock put a test light on the injector wires and see which is hot, check all wires for hot just to see what happens. Then hook up the box to the injectors and re check, if they are wrong you will see the power going to the other side.
 
I double checked that it has a good ground by doing a continuity test from the ring connector (that i mounted to the chassis behind the steering arm) to another bolt on the chassis just to be sure, so it should be grounded (hopefully). I'll check the wires on the injectors as you said to, but right now I suspect that's the issue. If that's the issue, how do you go about disassembling the plug to switch the wires?
 
Just checked the injector wires....I'll attach the pictures and it will be easier to explain.

The yellow wire with pink tracer (next to yellow/black on left side) is the hot stock injector wire. The solid yellow wire on the right hand side of the picture goes to the pure logic box, and it is also hot. However, the the pure logic injector plug, neither wire is hot. This is the case on both PTO and MAG side.

In this picture, on the bottom right side of the picture, the yellow and red wires are going to the injector, and neither of these are hot, but the yellow one should be.
I am stumped at this point.:face-icon-small-fro
 
Just swap them and test it, its either that or a bad box. if your careful you can take the pins out of the plugs and swap them over, they have little catches to hold them in place.
 
had to switch my wires on pto injector...easy to do..little spring tab on wire end then it slides out of housing and swap..the directions on the swap should be on purelogic website or alttitudes..which is the same
 
You need to switch the wired around in the plug. Make sure the red goes with red, and it should fire right up.
 
Switched the wires in the stock plugs like you guys said to do and it fired right up! Thanks for the help everyone!
