I have done everything to this vehicle,The Bruno fix,New Battery,New Starter,New Alternator,New Thermostat and still the same darn problem if I drive and I get to where I need to be come back and the darn thing does not start.I am at wits end with this vehicle got a gallon of gas for it(To burn it)

1989 BMW 535ia 102ks(supposedly, carfax also claims I am the only owner,which Im not)
