Alright, here is the deal. I have been trying to get this motor started and have gotten to this point. I have spark and am almost certain I have dizzy timing right (although it wouldn't matter, read on). Fuel is running through the rail and the injectors are pulsing. With all of the cranking the oil smells like fuel, so it is probably getting that. Here is what is really disturbing, compression test results were as follows:
1 - 1512 - 1503 - 1504 - 210
These results were gotten on a cold, never ran rebuilt engine. The head was milled .009'' and the cyl walls were deglazed but not honed. These are chrome-moly rings.
The motor is a rebuild, and I know it needs a new intake cam gear, but surely that cannot explain the result for number four, can it? Anyway, it sputters a little and backfires on starting fluid. I get a little smoke in the timing cover, but that is just blowby I would assume. Any Q's just ask, please help!
Super weird compression test results!
Here is an update:Last night I reset the timing to stock, turns out I was a little off. I don't think I banged up any valves though since I always rolled the engine over by hand before making an attempt to start it, and no valve clearance issues. The compression test results are looking a little lower, but more consistant. The new results are:
1 - 1052 - 1353 - 1224 - 145
I know that is out of spec, but a few drops of oil gives me:
1 - 2202 - 2103 - 2104 - 225
If not for number four, it would meet spec for total deviation. Now here are the new questions:
1. Does this indicate anything to anyone? (the engine has never been ran, and the test was done cold, so I know ring clearance is obvious, but anything else?)
2. Am I putting too much stock in these numbers for an engine that has never ran, and the test done cold?
Any new input would be great, and thank you all for the help so far.

I did, just a re-ring. When I got the car it had no head on it, so I thought I might as well put some clean rings and bearings in it. It almost started yesterday, but now I am having a weird fuel problem, and am afraid I may have damaged the computer. The computer's light (and CEL) should be on anytime the engine is in KOEO, right?
Re: (180fan)
I have fully lost spark, and have no injector pulse, also no CEL. I think it just happened from the harness damage. Anyway, I need to find an ECU+engine harness if anyone knows where I might find one for DOHC S13.
Re: (Chezedik)
Turns out that what has happened was a loose battery cable going to the starter's positive side was grounding out. Not a lot, but enough to make the system null out. When it got moved, the computer came back on, without problems. Seems this has been my injection problem all along.
