I've built a few engines and have had them flood on me, but nothing like this.
I put a half bridge 13brew in my FD that I built and it started on the first try, ran great actually. I was going over the usual checks and letting it idle with the occasional dickin' around with brapping the throttle. I even took it around the block.

I shut it down and started it several times that day, getting it up to operating temp every time. It never got bone cold between starts.

The next day I went to start it up and it didn't even try to start. I let it roll out of the garage and I gave it a pop from the clutch followed by some cranking, it burped and rattled for a second and died. I then had my wife push me down the street, hah, and it fluttered and tried to start but it never caught.

So I did the old fashioned way I've been accustomed to: pulling the leading plugs, cranking and cranking with the EGI fuse out till she puffed no more, put MMO in the plug holes and put a different set of plugs in and tried to start. NOTHING! I did this several times already and have grown upset and frustrated. This trick always worked like a champ for me.

I'm thinking about bringing a friend over with more muscle than my wife so we can get it rolling really good and try a good pop start in 2nd gear. It seems the only time it tried to start was when I got it rolling.

I'm afraid of a pull start method since I've heard of people spinning a bearing, so it would be nice to avoid that, not to mention I think I would need to pull my bumper for that crap.

Anything I could be missing?

push start failed. Ran that thing as fast as my friend's and my feet could move, nothing. We tried 4 times before giving up, tired, and sad.

It is a new motor, they will give you hell sometimes.

I would check these first

Fuel Pressure
Fuel Injectors
Spark to L and T
Compression, Just Check

then

PULL START IT

How would pull starting it cause a bearing failure? The oil pump is running. If you mean a trans bearing failure then yes if it was a Automatic

if you dump the clutch while rolling at a good speed you will most likely bring the rpms up high before oil has had a chance to get to the bearings. I know of one person who grabbed a bearing, but hes rebuilt and raced so many engines that one is bound to fail.

I've got all of the above listed except I haven't done a comp test. Not really worried about it since it did run. I think im going to get some 50 weight in there and start it with some ether. Hopefully I'll have an answer this evening.

OK I got it started again.
I didn't even pull the plugs.

I cranked it with the fuel pump disconnected
Poured straight 40 weight in the intake manifold
Sloshed it around a few turns
Shot some starter fluid in the manifold
Plugged the pump back in

Fired up no problem.

BUT OH GOD THE SMOKE! It is acting like a shot oil control ring it smokes so bad. I drove it out of the neighborhood and parked off the side of the road and let it run for about 5 mins with no signs of it letting up. Some lonely old lady pulled off the side of the road to see if I was ok and we talked about the housing market while my car blasted smoke everywhere.

I really hope this is just all the oil in the intake and exhaust that I've been dumping in burning off because it would suck for an oil control ring to **** itself even though it ran smokeless the other day.

I let it sit for 30 mins or so and fired her up again. The smoke continues for about a minute then vanished. Either the manifold was so coated in oil that when I let it sit all the oil ran into the engine OR an oil control seal or ring was still seating and it needed a heat cycle which I've never heard of.

Drove it around a while, got gas, got the idle down under 1400 so it seems to be getting better compression as I was only able to get the idle at 1900 when I first started it.

Ive pull started my FD several times. I just leave it in first and have someone pull it with my blazer. It works every time.

That's normal, the motors compression should improve in it's break in period a little.
