Fresh Build Turns over no start
Ok guys been working on this a while, long story short its a 2.4lr awd converted galant. I also did a wire tuck, but given my background(avionics tech) i know what i was doing. I metered every wire, from power to signal to ecu to ground to everything in between before I even attempted starting it. NOW, I am unfamiliar with the evo ecu and what not, but I know that the Crank angle sensor can cause no fuel and no spark, but does the Cam sensor tie into ignition at all?
Also how would I go about checking with spark with a aem cdi box? I have about 20 psi at my fpr but i pulled the plugs and they don't look fired on, and there is not a hint of e85 smell in the cylinders. Now I know that my CAS working perfectly fine before I did the rebuild, and yeah I probably should have got a new one, but that was well over a year ago lol (deployed alot) Now if i installed the Cam sensor plate 180 off would it not start? I just need some ideas
Thanks in advance!
Things to know maybe
Id2000
aem twing fire CDI
evo 8 ecu
its been flashed with a starting tune from TSComp

I don't think it's possible to put the cam sensor plate in 180* out. One of the slots is slightly larger to only fit in one way if I remember correctly doing my build. A bad cam sensor (or something causing a faulty system) could definitely cause a no start issue if the ecu can't read where the cams are located.
Even though you have experience with wiring, I would double check all of your wires and grounds. People make mistakes.
And make sure your CAS isn't backwards. I had mine backwards when I built mine.. went through all the troubleshooting and narrowed it down to CAS so I bought a brand new one. Went to replace it and had one of those "wow i'm an idiot" moments haha

what do you mean backwards on the CAS. Are you talking about flipping it when you bolt it on. I was under the impression that if you put the crank plate on the correct way you couldn't flip the sensor. You wouldn't happen to have a picture of the correct way to install the cas would you? lol I tried searching no avail.
Is it not getting spark or not getting fuel? Can you spray the into the air intake and at least get to fire over a couple of times? If so, check to see it the e-85 rusted your injectors. Happened to a friend of mine. Car down for 2 months, e-85 killed the injectors.

Its not getting fuel and not sparking. Its fresh e85 that i just put in the tank yesterday.

you mean whip out the oscilloscope and look for the out at the pcm? I checked the main box, didn't check the fuses inside the car yet. Also I noticed that the map i have had a immob of 8520, i know you can have periphary bits that turn that off, but should that read ffff? just a thought. Cuz my key doesn't match the ecu i know this, so i know that the immob cuts the efi circut
yeah I have a picture on my laptop I'll have to wait until I get home to throw it on. idk how I did it, the plate might have been backwards also but I don't really remember. lol
I would still check your cas and cam sensors with an ocilloscope. When I bought my car it had a brand new engine installed I got maybe 400 miles out of it and then it blew. When I put the new engine in the cas was reused and I had crank no fuel no spark. Turned out the cas had somehow been damaged the the engine blew up.

actually, could an ecu issue cause it to not start? I don't think I've ever gotten this car started before with this ecu.. last time I thought it was the immob though.
