Cranks alot when starting warm

[whacked]

I have a 04 it starts great when cold after I drive it for 10 miles or so shut it off and try to start it again it cranks for like 7 to 8 seconds before it fires back up. Any suggestions? Oh yeah it happens in cold and warm weather from Wisconsin.

Thanks

Could be a rail pressure issue. What's the service (injection system) history, mileage, fuel filter replacement?

71,000 miles new fuel filter about 5,000 ago bought it new in 03 first time it acted like this. Never had it in for anything else but for warranty issues.

Hard starting is a symptom of injector failure. You should have received an injector "Special Policy" letter from GM, you may want to review it. Maybe take the truck to the dealer to have them look at it under the terms of the Special Policy.
