I get 2 error codes from my 1992 Honda Accord. Error Code 15 and Code 43. Can someone help me troubleshoot these Errors?

15--Ignition Output Signal. Change the Ignition Control Module inside the distributor. Here's how to do it:

This is a good time to also change the coil and rotor.

43--Fuel Supply System. Possibilities include:

. Main Relay--I would replace the main relay on a 15 year old Accord.
. Fuel Pump--jump terminals 5 and 7 and see if the fuel pump runs. See Sticky.
. Fuel Filter--see Sticky
. Fuel Pressure Regulator--see Sticky
. Fuel Injector
. Oxygen Sensor--see Sticky for how to replace the sensor.
