My son and I just replaced the fuel filter and right side fuel pump in our 2005. It sounds much better (no more loud whining), but when my wife took it for a “test drive” it immediately went into limp mode. Getting error codes P2104, P2111 & P2112. We’re unsure whether to believe that the TPS or throttle body went bad during the few days it wasn’t running, and wondering if it could be a bad fuel pump causing the problem. Could a bad fuel pump cause these error codes? Any other thoughts or suggestions on where to start troubleshooting? Thanks!

It could be as simple as needing to reset the ECM. Try disconnecting the positive battery cable for 10 mins. This should reset the system to the new device.
