what would cause the SUV listed above to sputter and backfire? It feels like it's not getting enough power also barely accelerates. it's not staying cranked and shows lots of codes, but can't figure out exactly what it is causing the codes to show.

Good morning,

Can you list the codes for me so I can see what you see?

Can you check for fuel pressure? You can rent a tester at a parts store.

Can you tell me if there is a RPM signal on the tach when you crank it? I want to see if the crank sensor is sending a signal to the ECM.
