My 1999 bmw z3 will crank but will not start , code A9 & 44 shows up , air pump keeps running when ignition is on & drains the battery out.engine light & EML light comes on.


Not sure on this one.....if it's "drive by wire" that means the accelerator pedal is connected to the intake electronically, and that may be where the A9 code comes from. Saturns are drive by wire and it's a common failure point for them. spark, compression and gas is all you need for the engine to run. you can put a fuel pressure gauge on the rail to determine fuel, assume that the compression is good, and pull a spark plug and ground it while cranking to see if gets a spark...

I need to know the code dtc44 for a 1990 Buick Century


GM OBD Trouble Code 44

Auto Systems and Repair

Oxygen Sensor Error (Lean Condition Indicated) The ECM receives a signal from the O2 sensor based on the amount of oxygen in the exhaust. If there is excess oxygen in the exhaust, it is in lean condition and the O2 sensor voltage will be low. The ECM uses this information to adjust the amount of fuel delivered to each cylinder.
Fault Code Description
  • 44 - Oxygen sensor error (lean condition indicated)
  • On V-type engines with two O2 sensors, code 44 would indicate the left bank sensor is lean
Symptoms
  • Lack of power
Common Problems
  • Faulty O2 sensor
  • Engine vacuum leak
