Code reader for 1987 BMW 735i 3.5l? What brand, model, and where can I buy
one? OBD I or OBDII is for 1988 and up. Without going to dealer for
diagnostic I need to know the failing code and equivalent meaning.
The neighbors 735i will crank, has spark, has fuel smell when plug removed
but will not start. I can't tell what the solution is without a code
reader. It could be a sensor, fuel pressure regulator, fuel filter, etc. I
have a BMW maintenance manual but it refers to the dealer for service.
Otherwise it's tow it to dealer for diagnostic and perhaps repair. The
vehicle had a water leak. I replaced the leaking radiator/heater hose ($144
dealer/ $79 auto part) and water pump ($59 auto part). Now it won't start.
Had to charge the battery since neighbor had cranked engine for so long it
was near 0v. I haven't checked compression on all cylinders yet. It may
have a bad head gasket leaking water as well.
