Code 42 points to the following problems in a 1998 Neon. It could be one or more of these issues. P1282 - Fuel Pump Relay Control Circuit

P1388 - ASD Relay Control Circuit

P1389 - No ASD Relay Output Voltage At PCM

P0460 - Fuel Level Sending Unit & Circuit, No Change Over Miles

P0462 - Fuel Level Sending Unit Voltage Out Of Limits, Too Low

P0463 - Fuel Level Sending Unit Voltage Out Of Limits, Too High You will need to have the car scanned for DTCs (Diagnostic Trouble Codes) by a shop or parts store with an OBDII reader to determine which problem is causing the car to give error code 42.
