no spark after driving

[Tims_240]

well i finally got my car running again, so i was driving it all around. After i made a few pulls i started slowing down, and then i noticed i didnt have a throttle at all, i could push down on the pedal and nothing would happen...then car died, so i pull over, and look under the hood and mess with a few things, just to make sure all of my connections were good, and it starts right back up.so i drive it back to my house, and turn it off and go inside, and then later about 2 hours i go out and go to start it again, and it doesnt start, so i mess with the same connections again and nothing happens, so i check for spark, nothing. so basically i let my car set and now it doesnt want to start.any ideas?btw, i checked for spark at the coil, nothing.-tim

i have heard of power transistors failing like this, is there any way to test the power transistor, and would there be ANY spark at all if this failed?-tim

i also went out to test the codes today and my ecu light wouldnt light up.-tim

If your ECU doesn't even light up, check your battery. How old is yours? Sounds basic but when I had my first rebuild done, I couldn't figure out why the car wouldn't stop, and I tried everything except the battery, and the battery was the culprit.

well i rechecked the codes and the light worked, i mustve been doing something wrong, anyways i threw codes 11, 12, and 21.-tim

so its either the camshaft position sensor or my mafs, i have a z32.i am thinking it is between these obviously for the codes that were thrown, also because it was such a sudden failure. like i walked outside and my car wouldnt start.
