runs but cuts-off

Asked by Kyoshi John Jul 09, 2016 at 08:22 AM about the 2006 Chevrolet Tahoe Z71 RWD

Question type: General

My 2006 Chevy Tahoe Z71 starts and runs in the
morning. After a few days, it cuts-off. A few hours
after that it will start up. I did get a Evac leak code.  
I've replaced - fuel purge valve and fuel canister.

Evaps don't cause a NO start, If you have no other DTC codes. Check fuel pressure at the fuel rail use a gauge to read PSI... The pump can be failing IF pressure is LOW change the fuel filter before replacing the fuel pump.
