Can changing fuel pump module, ignition cylinder and switch, or powersteering motor cause problems on fuel gauge or tps?
I recently took my 07 cobalt to have recalls fixed where they changed fuel pump module, ignition cylinder, ignition switch, and powersteering motor. The day I left the service center with my vehicle the fuel gauge wouldnt read at all few days later engine light came on took to have codes read. Codes were P0463, P0121, P0461. Would them replacing any of them not being installed correctly cause these codes.

Yes but sou cold a sticky throttle plate so try cleaning with choke cleaner on both sides. Also a low or weak battery will throw multiple codes but let the service manger look at it first.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
