Just to sum up what's going on.

S13 red top developed a small tick in the head, so it was decided lifters needed to be bled.

I zip tied the chain to the sprockets before hand and had the engine at TDC verified by crank pulley mark and a dowel in cylinder 1.

Bled the lifters proper and installed the camshafts.

Went to start the engine again and it cranks but will not catch.

Car has fuel
-40psi on FPR
-injectors click properly
-removed rail and let them fire into a box and all 4 spray properly

Car has spark verified by pulling a plug and ground the plug to the VC and cranking the engine. All 4 coils give healthy spark.

Timing seemed to be spot on with the intake cam dowel at 10 o clock and the exhaust dowel at 12 o clock.

11 links between marks, 20 pins etc etc

CAS is also set right.

I'm running out of things to blame for this.

The car drove right in to the garage.
Help :(

Ground wire on the coilpack harness near the back of the head?

they're HKS step 1s, i've rotated the cas all the way forward, back, middle and anywhere in between

^^This happened to me when I did a head gasket change back in the day... Weird as it may sound, it took about 25-30 cranks before it 'choked' a few times... then eventually started up. You may want to pull the fuel pump fuse and prime it a bit before going for a start. Anyway... My car ran like dog shit for a few miles... then purred like a kitten- My non-mechanic assumption is that it just took a little while for the the electronics, lifters & whatnot to sorta sync back up.

i've had weird problems like this before where it randomly lost spark in 2 cylinders and that was remedied by cursing at it and pluging everything back in. its just this time there isn't anything that stands out as really wrong.

I had this problem before. Took me forever to figure it out. Your motor needs to crank alot and fast so either 1. have someone tow you and drop the clutch and start it that way or 2. Jump it to a running car and crank crank crank that bitch. It needs alot of amperage and revs to initially start.
