hey to all-
new to this site.
i have a 535 and its a dream car but...
it now just wont start.
changed the fuel pump,checked air flow,check 02 sensor,checked crank shaft sensor, checked for spark,fuel,checked for vacumm leak, check plugs that are full of fuel....so its pumpimg too much fuel and backfires but keeps cranking and wont start. no check engine on or any warnings signs---
I think my option is try now the cars computer...
any ideas...
thank you
