On my 2000 Yukon, I just noticed that when I get in to start it cold she fires right up. If I get in to start it after I have driven some where and it sits for a few minutes the first time you crank the ignition it just spins, nothing abnormal but it doesn't actually start, the second time it fires right up. If I expect it to happen and just turn the key enough to crank it and then let off and then try a second time to start it it will fire right up. I had a buddy say he had a similar problem with his 03 GM (H2) and he had the fuel pressure regulator replaced and it went away but I had a local shop check this truck out on Thursday after I bought it and he said the Fuel Pressure Regulator was ok. ...... I am beginning to wonder if he actually checked it.
Anybody have any ideas?
