running rough, then wont start after rebuild

Ok, looked through threads, searched etc.

Ok just got my baby started St. Patty's day night with plenty of irish blood sacrifice LITERALLY.

On to yesterday, tried to take her for a quick spin, next to no power, went home and discovered a MASSIVE coolant leak from thermostat housing at the heater hose ( the one that runs into the fire wall.) Also, found that injector 4 had a leaking o-ring. Quick trip to parts store. Replaced hose clamp on heater hose, and all injector o-rings. CRACKED the fuel rail on reinstall, and didn't realize until attempting to start and in sprayed fuel all over the coil packs and transistor. Picked up a 1g fuel rail and FPR. Installed. No fuel leaks.

On to try and starting. Motor cranks, can hear fire, but dies IMMEDIATELY. Checked spark, good. Checked throttle, cable fell off of half-moon, fixed. Still will not stay running. Checked timing, no skipped teeth, belts are tight. still wont stay running. Checked vacuum hose connections up by intake mani, routed correctly and connected. Still no run. Battery is good. My buddy/ extra pair of eyes said he saw a spark from behind the injectors by the transistor.

Please HELP! I am at my wits end trying to figure this out. I need my DSM back on the road.

try testing the ignition control module aka transistor, and your coil packs. Just use the search button there is a write up on this from the member Luv2rally.

RESOLVED, well... kind of. Okay, so I was trouble shooting, discovered that i had forgotten 2 injector seals (the big fat 1/8" thick o-rings), causing a lack of compression or something I guess. Replaced those and she ran.

Next, to reduce the time I would spend tracking down Vacuum leaks, i just plugged off all of my emissions controls. I know, I know, not the proper or prettiest way to do it, but I'll remove all of the garbage on a day off after I get her purring. Still, acting like a MASSIVE vacuum leak. I begin double and triple checking all of my FMIC piping couplers. I get to one that is next to turbo and should spout charged air. I have a buddy start her up and try and rev her with these two hoses undone. Sure, the engine can breathe a little better now and holds damn good vacuum. i put my hand next to the "charged" pipe and, NADA. The Turbo isn't even spinning. So I have come to the conclusion that I need a new turbo.. Joy... Time to upgrade.

Btw, What would have blown it, would be when three valve heads on cyl 3 decided to go right through the top of piston 3 and wound up in oil pan, I suspect that metal floating around went through the oil feed lines and wrecked the bearing.
