my problme is that in the morning or after my car has sat for 8 hours i go to start my car i let the fule pump run untill it stops then i crank it over i can crank it for ever without even a stutter i can stop then crank and it will sputter and then crank again and it will start


when i changed my fule filter it helped for a week than it started again so i changed the fule preshure regular and no change

any help would be great

i forgot to put my info in i have a 98 slt yukon

I have the same problem. I did a search here and it looks like you got a bad regulator or leaking injecotrs. I've ordered the Multec II ugrageded injection for my 96 and I'm hoping it takes care of all the issues. Do a search on cold starts and you'll see loads of info. Good luck.
