have someone check fuel pressure and or regulator


Is it difficult to get gasoline into the tank as well? I knew of a Chevrolet Trailblazer and a Kia SUV which had a similar problem. The charcoal canister was bad and caused vapor lock. There was no or little air getting out while the tanks were being filled so that cause the fuel station's pump to click often because the gasoline was backing up, then after it drained you could add some more. The Trailblazer ran like crap on a full tank because of the vapor lock. Explore that option, and try not briming the tank, leave some breathing space.
