I will try to make this short..
I have a 1999 olds bravada, been kind of running rough.. missing alittle when driving. Now a bigger problem. I can start it, and it runs great, problem is.. when I shut if off it wont start. turns over fine, and has a brand new battery.
Sounds like it's not getting gas(even tho I can hear the fuel pump running). After it sets about a half hour it starts right back and runs great untill I shut it off again.
