light on reading as large EVAP leak, had solenoid on front of tank replaced last year at dealer, had some other part replaced two years ago (they had to drop the tank to access it) on top of fuel tank. Replaced fuel cap with new OEM cap from dealer, still an issue. This is frustrating as the vehicle runs fantastic, no issues whatsoever. could this be something simple like an PCV or EVAP control in the engine compartment. 2006 Silverado 5.3 Vortec w/ approx. 110,000 m. Like I said the truck runs fantastic.
JA: Does the light stay on, or does it blink?
Customer: Stays on constant, had a friend clear out the codes, twenty miles the light came back on constant.
JA: Are you fixing your vehicle yourself? What have you tried so far?
Customer: Beyond the above actions nothing, prefer to resolve myself, but and constrained by time and extensive tools.
JA: Anything else you want the mechanic to know before I connect you?
Customer: No, If it is a problem that I an not able to handle I want to be prepared when taking it to a facility.
