Well.. CRAP!

 
My ECU does not have the trouble shooting upgrade yet, so I checked the plugs while turning over the engin with  fuel pumps off (no prob on as of yet) and I have spark.  However, we do not seem to have any noise coming from the injectors at all.  I tried on both A and B to no avail.  After checking to see if any wires had come loose and other basic trouble shooting, I was becoming frustrated (and a little angry) and for the first time in my 4.9 year build I was feeling a bit discouraged.

Just got back in from a night out and read this..
Sorry if you've thought of these...but.. here goes..

First off, Once we beat this gremlin, I vote we adjust a set ccrew on the intake throttle body to keep from doing this (closing it all the way down).. if one doesn't exist, lets install something on the butterfly shaft of the mistral intake to serve as one. If I remember right, this is the location that their throttle position sensor goes, something we arent using.

Now.. to the problem.

Ground points.. something vibrate off? (i know.. you said you checked for loose wires... )
Fuel pressure reading during this? (we have a steam gauge on the regulator for those who dont know our install)
Circuit breakers?
Connections on circuit breakers?
Cold start/injector switches connections?

Im guessing the crank angle sensor is connected if the plugs are sparking..
ECU in mode ZERO..

Battery charge status? I guess if we are cranking we have juice.. but how low is the volts dropping when we hit the button.. I cant remember if the charging systems are online or not..

I SO wish we had thought about getting the EC2 troubleshooting upgrade before Tracy went on vacation.. the injectors and plugs test mode...

I go in to work 11-7.. i will holler at you later in the day..
I wont read the email before I go in.
