half crank? help@

[sr28]

Hey guys, i just did a t28 turbo upgrade on my sr20 red top. car was running great for maybe 5 minutes then it started crapping out and bogging. So I decided its time to switch to bkr7e from 6. I gapped them at .030 put em in, and the car wont start. It gives a half of a crank, then stops almost as if something is not allowing it to fully turn over. If i keep cranking, it will reach that half way point then it sounds like the crank rolls back into its starting position.

sigh... help!!?

check your timing...is your CAS sensor loose?...from the way you are describing it when its out of time it can almost stop in mid stroke lie the way you are describing...hope its nothing serious.

i jiggled it around a bit and it started.. once.. but now its doing the same garbage again.. could the sensor be broken? it made a pretty nasty sound when i tried starting it last time so i stopped..
