1)I was wondering does the mazda rx8 have a bad fuel pump also(basically do you have to change the fuel pump as often you change your spark plugs or these fuel pumps are good for 100K). Have you or anybody you know changed there fuel pump around every 30K.?

2) How would you know that your fuel pump is bad/broken/blown/needs to get replaced?

3) Is this the procedure to unflood an rx8 pushing the gas pedal to the floor (which signals the fuel system to supply no fuel at start-up) and crank the motor for upwards of a minute. This tries to force unburnt fuel out the exhaust port. Then let the engine sit for a minute or so and try starting again, if not can you tell the right procedure or any other procedores you might know how to unflood this car.

4) Also can you tell me about the procedure about disconnecting the fuel pump when to unflood an rx8(what do you do before and after you disconnect the fuel pump)


5) When you do have a flooded rx8 i read that people clean/change all of there spark plugs is this true and why do you have to do this? Also when you have a flooded rx8 after you unflood it do you also have to get a new fuel pump?

Thank you for your time

1) Mine is still working fine at 60,000 miles. Nobody on here
has had any problems as far as I know with the stock RX8 pump.
Any pump will fail if you run it without fuel for long.
The fuel is used to cool it.

2) Check the fuel pressure with a full tank of fuel.

3) That appears to be the Mazda recommended procedure. If that does
not work set the rotor at 180 degrees BTDC and use a small plastic
suction tube extended down to the bottom of the engine using the lower
spark plug hole for access.

4) Same as 3.

5) Not necessary if you let the plugs dry out/off. Nothing to do
with the pump unless you run out of fuel.
