I checked FUEL PUMP SENSOR, and it made correct clicks when tested with 12V
also verified FUEL PUMP with just a jumper wire and the PUMP turns on
I got 1221 code from the CEL test
the car tries to start but fails to stay on, when it does turn on it's IDLE IS CRAZY
don't know how to test Mass Airflow, it has 4 pins, dont know where to start there
any more suggestions, also does MIDGRADE make any difference than premium?
I just started using midgrade since 2 weeks ago, it's finally like quarter tank a little bit after almost like check fuel light comes on, 3 weeks ago it died on me like a little bit after the check fuel light came on, could the cold temps affect the fuel at all? any info would be aprriciated
