It lives!

Whew, got the car running again with the turbo, but it took some doing. We did have spark, the fuel pump was working, the alarm-ectomy was successful. However, it still wasn't starting. To debug it, here's what I went through today:
  • check spark (ok)
  • check fuel pump and flow (ok)
  • check for engine codes (none)
  • check for blockages in the intake plumbing (none)
  • sit and look at the engine for awhile (thinking ...)
  • take off all intake and install old Jackson intake (bypass turbo and intercooler) - It runs!
  • put back on some intake pieces (turbo in-line, bypass intercooler) - No dice!
  • put back on one intake piece (bypass turbo and intercooler but AFM in right place in terms of intake length) - No dice!
  • tighten the crap out of the hose clamps - It runs!
So, here's the deal. It turns out that the silicone connectors for the extra shiny aluminum tubing we have sitting around don't quite fit right. This means that even if you tighten the clamps up pretty tightly, they still have lots of air leaks and the AFM gets really confused. So, after hooking up all of the intake tubes again and tightening the crap out of the hose clamps, it finally ran with the turbo, but even then there were still lots of leaks. Oh yeah, and I almost burned through a heater return line with the new exhaust placement.

Maybe tomorrow I'll figure out a better way to connect up the intake tubing. I'd really like to take it for a test-run and see what breaks.
