Yeah I hear the cold thing. I have a garage, but the heater blows ( And it isn't in the good way) I'd pop the fuel line off at the filter and crank it once and see if the pump is actaully pumping.

I don't know much bout rotarys but I got fuel air n spark but it sounds like its not running right. Like compression loss on one side.. idk wtf is going on. But u know how a piston motor sounds when its running on two cylinders that's how it sounds

What you describe to me almost sounds like a bad injector. Try this:
-unbolt the upper intake manifold from the lower, but don't disconnect anything else. Just lift the manifolds apart by about an inch or so
-jump the yellow test connector at the passenger shock tower (it might have fallen underneath the airbox)
-turn the key to IGN/RUN
-the fuel pump should now be running
-look down the lower manifold. Are any of the injectors hosing fuel into the engine?
If the answer is "yes", you have a locked injector.
Yep, I know you said they are new injectors, but new parts fail as well.

"Cars are like sex. At first, every guy thinks he's great at it. But when he gets into it a little, he realizes how much he really has to learn."
Some people bite off far more then they can chew and when they hit a problem they don't understand, instead of admitting it, they just bungle around and cause more damage.
That said, I might be totally off base on my injector diagnosis. But based on considerable experience with bad injectors, that's what first came to mind.

Sorry, I didn't quite follow the thread. Are they actually brand new injectors? That must not have been cheap. Just for future reference, you almost never have to buy new injectors. An injection shop can fix existing units in most cases for less then $30.
OK, so at the moment, do you have spark?
And do you have fuel?
