why does my fuel pump run all the time when key is on
...well you need fuel pressure for to run properly...it is only through pulses to the injectors that you'll keep runnin'...like the ignition system you want it to be doin' it's job...the foul plugs could be due to any number of factors, you should use the OBDiagnostics built in, perhaps the motor is worn---is this a rotary?
the car is a 280z 1978
you know there is an ACC position so that you can make so you can still listen to the radio without turning the ignition on~
