-Cam Angle Sensor.
-bad wiring, or grounding problem.

CAS controls injection timing directly

how is this a Real Urgent Serious problem?
Just check your pipes, hoses, and wiring

because I am supposed to be driving at an event tomorrow...
looks like that might not be happening now
I know that its electrical..
I don't think its the cas. I am going to go over the car with a fine toothed come. Just start back at basics. Then maybe get a pinout and check the resistance in any can all wires that have to do with the injectors..
wish me luck!

......I don't think its the cas......
Save yourself some time and confirm that the problem isn't the CAS (which was recommended above).
Confirm what is working first.

checked that the ecu is getting the cas signal and it is
i also checked the injector drive inputs at the ecu and they went up to .2V when I turned they key. I am wondering if that could me that there is a bad ground somwere..
this is getting annoying

Damn, I thought this thread was going to be about how to put out a fire in the engine bay.

no ha
but anyway I thought I had the problem fixed
and i am wrong.. now i have fuel and spark but still no start...
I tried playing with the cas a bit and nothing at all. I am gonna pull the valve cover either tomorrow or wednesday and make sure the cas is set up properly on the compression stroke and not the exhaust stroke. thats really the only thing left I can think of. if not then i don't fucking know..

you can tell just by taking off the oil filler cap. You can see the one of the exhaust cam lobes and if its pointing towards the driver side then its compression stroke.

Soo you bought a new harness and it didnt fix your problem?? if so damn, it sucks wasting money, thats why you FIND the problem and FIX it. Dont be a parts changer be a mechanic...
The injectors should be hot no matter if the car is on or not.. they will have power as long as the battery is hooked up.. No that doesnt mean they work all the time, someone is bound to think that and say otherwise.. but check that..
Also pull in injector out of fuel rail and see if it is physically shooting fuel.

Also is your timing correct? just basics before the more labor intensive..
