[Gmecm] Cold start problem

[Bill - Comcast]

I'm having a cold start problem on my wife's '88 Buick Century wagon and 
am looking for some advise.  This is a 3.8L v6 with DIS. When trying to 
start it will crank a second or 2 then fire and then backfire and 
stall.  We have to try 10 to 15 times before it will finally wheeze to 
life.  Once it starts it runs fine,  no skips or hesitation.  The 
problem occurs only when it's stone cold, after running for even a 
minute it will repeatedly start fine.  It's not setting any codes so I'm 
not getting any help from the ECM.

This started suddenly a couple of days ago.  Before that it fired up 
quickly warm or cold and ran well.  I thought maybe something weird with 
the CTS ( remember, no codes) so I changed it (it was cheap and easy 
anyways) but it made no difference.  Anyone have a thought on what to 
look at next?

Thanks,

Bill
