headgasket/ compression test

Hey, I was wondering if anyone could give some advice on whats goin on with my S13 SR motor...

ok, so I took the motor out and replaced the headgasket with an apexi one and when I put the cams back in im pretty sure i got the camshaft alignment procedure correct and I torqued the head down following the FSM... so when I go to start it, it doesn't want to... it just cranks but no fire... but if I turn the key on and then pull the fuel pump fuse quickly so only a small amount fuel is in the lines it'll start but die out obviously(lack of fuel pressure). but if i leave the fuse in then it just floods the motor. I did get it to run once but i had the throttle plate full open and it was idling rough and wouldn't idle without the throttle floored.

I did a compression test on it today and it read about 57psi on all cylinders so that worries me very much... im not sure if i did the test correctly so i'll retest with the help of my friend but if anyone has any info i'd GREATLY appreciate it very much.


By the way here's a list of things i've tested and are ok..
-timing (15degrees, second mark from the right)
-mafs
-TPS
-coilpacks, ignitor chip, plugs
-ECU
-O2 sensor
-temp. sensor
