  Summary

  Fuel Delivery Module Before replacing the fuel module for DTCs P0461 and P062A and other not start, long crank, fuel gauge accuracy and drivability issues, the technician should disconnect the electrical connector at the pump and perform a visual inspection of the connector for and bent, spread, or pushed out terminals. Repair any issues found. Reconnect the plug and perform a push pull push to ensure the connector is fully installed. Then perform 3 keys cycles and listen to hear if the fuel pump is operational. If the fuel pump is heard that indicates that everything is operating correctly. If the pump is heard replacement is not necessary, any replacement will function in the same way.

  Summary

  Clunking when going over bumps, potholes, or turns. During diagnosis dealers may find rubber separating from the bushing on the handling link (SOL S2102000004 Rev C. for reference). This is normal and most likely is not attributed to the noise. Please follow normal diagnosis and ensure all tie-rod and ball joints are properly torqued and if worn, replace. If diagnosis leads to lower control arm replacement, the tension link(s) should be replaced first then test driven to ensure noise has disappeared before any handling link replacements.
