expert input please on no start issue
 
I've been putting off asking this as I thought I could get her running....
but what are boards for right?

I had the whole intake and exhaust side off this winter and I basically replaced every gasket and vacuum line, omp injectors and replaced my pre-cat with bonez down pipe, had my injectors cleaned by cruzinperformance, new fuel hoses, new pulsation dampner, new acv etc etc.

Got it all back together, checked, double checked, put a little oil in the plug holes and turned her over and she started right up, idled at around 2300 rpm for a while and souned normal, then when it warmed it fell to like 300rpm and sounded aweful, so I revved it, it backfired, sputtered and then died.

It has not started since, I've even towed it around the block trying to pull start in 1st at nearly 3000rpm, and nothing. The plugs are soaked in gas. I've tried unflooding it like 8 times.

This was a good running T2 with a 40K Mazda rebuild that had some idle issues last fall when I took it apart.

Your inputs are greatly appreciated.

sounds like some vac leaks and flooding

After studying the vac diagram there is a line I'm not familiar with, which runs from firewall side of TB to LIM, above the cold start injection I think. A secondary injector air bleed perhaps?

This is what happens when your buddy who drives a Jeep hangs around in your garage while your re-assembling everything, talking to you....trying to get involved....lol.....distracting me!

It's gotta be that line.

Upon further investigation I don't believe I have a secondary air bleed. (S4 T2)

But I recall a nipple I think I forgot, firewall side of dynamic chamber by itself, kind of underneith, not one of the three. Anyone know where this vacuum line goes?
