Just got my 94 LSI back after 7 weeks in the body shop for a repaint (just repaint, dings only insheetmetal). It came out great.

However CE light is now on and morning starts are near impossible. It turns over but does not catch. If it does then it stops quickly. It takes 5-6 tries and pedal coaxing. Once started it stays rough for minute or so before reving up. Once reved up it starts easily for the whole day even with 4-8 hrs in between. Next morning same thing.

I had my local mechanic that I trust implicity and he could not get any codes to read out.

I brought it over to the local dealer (I know uh oh!) this morning and he claims he got a code for a bad coolant temp sensor that he claims could affect startup.

Anybody experience this or know if dealer is correct. Part is $54 and 2 hrs labor at $90/hr. UGH!

I was thinking maybe a bad fuel pressure regulator that lost pressure over night, 10-12 hrs sitting. Anyone know if a there should be code readout for this.

I tried running it for nearly a week to see if I could blow out any bodyshop dust or lingering paint fumes from sensors but no luck. even reset CE by disconnecting battery but it came right back.

Any comments.
