- Verified vehicle cranks but won't start. Initial inspection showed the air intake boot connecting the mass air flow sensor to the engine was missing. Air intake tube was located inside the cab. When we went to install the tube we noted the fuel bleeder screw by the primer was leaking fuel – was loose. We tightened the bleeder and primed the system. Vehicle started and ran. Noted the Check Engine Light was on – we scanned for codes and received P0420 (catalyst system low bank 1). Let the vehicle run and inspected for additional fuel leaks – none found. Let vehicle sit for several hours to cool off – continued to restart properly. Test drove without incident. Let sit overnight – restarted properly in the morning. Let sit until afternoon and vehicle continued to start properly. Monitoring fuel pressures thru the scan tool everything is within spec. Test drove again and reinspected for any fuel leaks – none found. .
