Having problems with your 2002 GMC Yukon Denali ?
Denali won't start on the first try. Then when you try again and let it crank for a few seconds it starts and runs fine. It has 90k and I changed the fuel filter and after I check the fuel pressure, it was 51psi. Also I put it on the computer and all seems fine. Any help would be great, thanks.
Check with advance auto store and ask if 51 is proper, thinking it should be 65 or better
