Question about 1991 Pontiac Sunbird
I think this code is defined as follows:
Fuel pump circuit fault or Mixture Control (M/C) solenoid fault or Electronic Control Module (ECM) fault/EGR solenoid #2 failure
Check your fuel pump relay as well - this could be the fault in the fuel pump circuit.
Hope this helps, Sherwin
