First it's the things that have been checked that will throw a code. Then it's things that won't. Last it's things in the system that haven't been touched on yet. If I leave anything out, I'm sorry. Please add it on. Here goes it.

Code items:
-Crank position sensor = wouldn't start or run at all. Code.
-Cam position sensor = throws a code.
-Throttle position sensor = code and failsafe mode (limits the engine to about 1300 rpm)
-Mass airflow sensor. Starts then dies. Code.

Non code items:
-Battery voltage and capacity. 13.5v 750cca
-Fuel filter and pressure regulator. (50 psi @ fuel rail)
-Vacuum leaks. Blue hose and white hose on top of engine to/from vacuum switch. Oil/air separator drain line.
-Corrosion on electrical connections. Power supply lug on driver side fire wall. Main engine ground. All starter connections. Ground behind engine electronics box.
-Found outside air temp probe stuffed up in the headlights.
-Switched green relays.
-Switched blue relays.
-Ran over 100 gallons of gas with fuel system cleaner.
-Switched keys
-Changed spark plugs
-Checked electronic's cooling fan
-Cleaned fuzz off crank sensor.
-Cleaned fuzz off cam sensors.
-DME reprogram.
-Changed brand and station of gas

Things that could cause problems and haven't been changed or swapped
-Ignition switch
-Dual water temp sensor
-Wiring

I think this is everything. If it's not please let us all know.
Happy Motoring.
