Engine Performance problem
2000 Cadillac Escalade V8 Four Wheel Drive Automatic 161000 miles

I have a 2000 escalade and had a fuel pump problem about a month ago. I replaced the fuel pump, and just recently the fuel filter, but now I have a very difficult time starting the vehicle and believe it is getting flooded. only happens when the engine is relatively cold (sitting for a few hours). Once the vehicle is started, it will run great except for an occasional hesitation under load (going up hill or giving it gas to pass). I am not sure what to check.

Thanks
