This morning I disconnected the battery to reset the computer because the "range" and fuel economy calcuation has been messed up. I reconnected the battery after about 5 min. turned the ignition on and things were back to normal.

Two hours later I went to start the car and it would not start. Sounded as if it was not getting fuel. I listened for the fuel pump and I thought I heard it. I tried holding the gas peddle all the way down to open the throttle body and the car started but it was rough and it would not idle. After a little while of working it I was able to keep it running but the RPM's were running high. I drove it to my garage and after shuting it down it would not restart.

Any ideas would be helpful. By the way the caculations are messed up again.

Thanks, Stephen

sounds like a possible ECU issue, holding it to the floor should have put it in "clear flood" mode. i would put it on a scan tool and look at temperature sensor inputs. sounds like the computer may be seeing a extremely cold temp. input and making the injector pulse width very long to compensate for a cold start up. was it running noticeably rich once you got it running?

Yes it was running rich. I could smell the fuel. As I drove it it got better but when I shut it down it would not re-start.

well if i were you i'd try to get a hold of a scan tool, or have someone check it out so you can see what kind of information the ECU is getting. If i was making an educated guess i would say either there is a temperature sensor input, a O2 sensor bad, or a ECU problem. Keep us posted on what you find.
