I recently bought a 2004 GMC envoy from a dealer. They replaced the fuel pump and on my way home I filled it up with gas and after a few miles it started pouring gas put of the clip on the fuel filter.. Which left my stuck on the road... Now my check engine light is on and like 5 codes come up when it is scanned.. Is there a fuel sensor or something that got ruined or something?
Fuel pump changed... Now service engine son light is on and like 5 codes are up. on 2004 GMC Envoy

Fix the fuel leak, clear the codes and retest. The leak itself would not ruin anything, but it could cause random codes
