Car wont start after rebuild, HELP!

[OMGkiwi]

the car just cranks and cranks, the timing belt is on right but it seems to spin over kind of sluggishly, did a comp test and was at about 120 across the board im assuming that will go up when the car starts up and the rings set.
I had to take a CAS off and I didnt really know if it had to be in a certain position to work properly, but when I turn it all the way towards the firewall, the car will "pop" and want to start, but only every so often. I cannot locate the crank sensor, or is that built into the coil pack setup? theres is a small round plug that is not connected, it is on the same bundle of wires that the injectors and coil plug goes, like I said its about 1 inch and round.
I guess the first question is what should I do to test if my cas is bad? also, when I turn the key to the on position the fuel pump does not prime, but after i am done cranking it primes.

HELP!
