I just pulled back-up fuse.
I'll try tomorrow and see if resetting ECU fixes problem

update.
Last night, I pulled back-up fuse and resetted ECU.
This morning, it started w/o any problem biggrin.gif
However, I was late for work so I had to drive away pretty soon.
I did not have time to let it idle for it to re-learn.
I'll try again tomorrow.

Sweet, I will reset it tonight and pull the back up fuse. Do you think I should just let the car warm up to its normal operating temperature before I get going in the morning?
Thanks for the update

What type of fuel are you using? It doesn't sound like you're having starter or spark issues.
Many newer cars running high octane Chevron gas run into cold start issues around this time of the year. Resetting the ECU allows the car to start easily with default mapping but once the adaptation kicks in the cold start issue may come back.

Mine just did this this morning. I run 94 Octane Chevron. I let it sputter for about 5-10 seconds and then it kicked in normally. We'll see how it starts tonight after it's been sitting all day...
