    check your battery connections and altenator, the CAS is located right next to the thermostat housing,on passenger side on the head

    now its sounding to be more like an air delivey problem check all your piping from turbo tom intake manifold, make sure everything is tight,i realy dont belive the CAS has anything to do with this, maybe your MAF but right now im guessing something not clamped or tightened enough check your vaccum lines as well, by the way what kind of mods are you running?

    I would say that it sounds like your mass air flow sensor is bad.

    Does it start with Starting Fluid? That would help in narrowing down the problem. If it starts with that, chances are its still a fuel problem. Do a boost leak test & compression test while your at it.

    I had an almost identical problem, found that the aftermarket fuel pump switch had a bad ground.

    I would stick with the basics if I were you. You said you have fuel and spark. Have you administrated a compression test?

    Maybe losing compression do to a bad head gasket? Definitely do a compression check!

    If you dont have access to a compression check you always could... ill say first this isnt the best way or most accurate but... Take the plug off the top of your coil pack, so the cylinders dont spark. Take a spark plug out, and plug the hole of the spark plug with your thumb or finger. Turn the car over, you should feel the compression. Do to all cylinders 1 at a time. If one or two seem to have less push or none at all, bad compression. Fuel+Spark+compression=combustion. If you know you have two check the third.

    I would also say compression test, If you dont have a tester most auto part stores will let you rent one. It sounds like valve timing from what you described as much as I hate to say it. Have you ever had the timing belt changed ?

    Pull the head off and take a look! Ive done it on my car 4 times replacing "bad" head gaskets, that turned out to be a warped head surface. You could have bad valves, a bad head gasket, warped head, improper torquing of head studs.

    Maybe you jumped timing when you started and bent a few valves? Might be worth checking your timing so you can know what happened before pulling the head off.

    Sorry for your loss man, good luck.
