Quick OBD2 code scanner question

Recommended Posts

HI, My car wont start this morning after i parked 30 minutes earlier. it has a 3 month old battery to that cant be the issue.

my question is:

Will OBD2 scanner tell me why the car isn't starting? if its the crack sensor, oxygen senson, bad immobilizer, starter rely, etc etc.

I am pretty broke now and dont want to spend $200 to get it towed to a mechanic and have it checked if its something I can fix myself.

Thanks guys.

If you plan on doing future work your best diagnostic tool is Durametric Software - but it it $287. (still much cheaper than the Porsche PST2 - $3500 or Porsche PIWIS - $18,000).

Some Autozone parts stores will let you "borrow" a scanner for a quick test but most generic scanners do not pick all the special Porsche codes.

Does it crank? If it doesn't even crank I'd check the clutch pedal switch or gear selector lever with an automatic. If it cranks but won't start I'd only be guessing. I'd pour in a couple gallons of gas just to eliminate the possibility the tank is empty (gas gauges can go bad).
