very dangerous.
and is caused by a double failure
the Fuel pump relay is bad and the power to it is stuck on.
very bad.
my online FSM has no schematics. its too new.
you need a real fsm or get help;
$4 day pass, see the pump, relay and power feed there.

these new cars with 14 computers are hard to diagnose.
the PCM sends a command to shut down pump, and can be ignored
the conundum is, did it send the command, did it get lost on the CANbus network or was the relay module asleep.
welcome to the digital age....
on the older Sx4, the key switch (ign. key) kills power to the pump relay and even if the relay welds closed, the pump will go down
key off, on new cars, even the key sends out commands. on the network (canbus)
im trying to build some cheap tools for this.... to see if the commands
were even sent.
is your car still under warranty? Suzuki is chapter 11.. so finding
dealers is a problem, in usa and now canada.
id sell it. but that's me.
