i was coasting to a stop the other nite (in neutraul)...and i noticed my tach lying on the zero..........wtf i thought to myself.....the car was running great just minutes before all this....a/f ratios were in the mid 11's under full load & was getting a perfect 14lbs of boost...anyway i could not get the car to start again..... i checked the plugs.......they looked good..........i checked the fuel system..........good aswell...........compression seems fine by listening to the motor turn over with the plugs out........the only abnormal thing i could find was that the idle air control valve was making a loud humming noise while the key was in the on position.........of course it would stop making this noise if i unplugged the electical connector..........or when the turbo timer shut down............any body had this problem or know wtf it could b............

I get that loud humming noise too if my car doesnt turn over the first time. It never use to do that before the non-sequential upgrade. If u find out why it does that please let me know.

As for the no start....for me it happens after a long 4 to 5 hour highway trip. My car wont start the next morning. I found out that my plugs were basicaly fouling out and I had to reclean them and put them back in. Im guessing I might still be running a little to rich. In town it doesnt happen. Did u check ur map sensor? Ive heard sometime that might come loose and will make the car not start. Hope something helps a little.....Im still a little new to this.
