I have a 1994 300zx non-turbo. Over the last 6 weeks, the vehicle has had an extended crank, when the engine is cold. I have tried some basic repair myself, but have been unsuccessful thus far.
I have changed the
fuel filter, spark plugs, battery, and the fuel pressure regulator. I recently read the codes that the ECU has and it 32 and 34, which is a knock sensor or a EGR valve/solenoid.
Any ideas or thoughts would be greatly appreciated.
