Replaced starter as it would not turn the engine over.Does that fine now but....I've got no fuel pump prime and no spark at the plugs. Is there a theft deterrent feature that shuts off both the fuel pump and the ignition.Battery was disconnected several times,would that make the keys become mismatched to the ecm,pcm or bcm??.For the past month had multiple times when the starter solenoid would only "buzz" and not engage.Then it would finally catch and start the car. Now I can't even hear the pump start with key on even though I checked the fuses for twelve volts and they were fine.What am I overlooking??
