RX-8 Won't start if drive hard-

Hi , I have 04 rx8 gt with 38,000 KM's. new coils and plugs ,

yesterday I encountered with a problem which happened to me two times before.

whenever I floor it hard with low fuel in it ( just before the light blinks)

the car won't start after switch it off for couple of minutes , it cranks fine just like to start but wont start at all like its flooded .

but it always it starts after a while , or sometimes it starts after doing the deflooding procedure.

and also have to note I have really bad engine mounts ,

what would be the reason to all this
your kind help is much appreciated.
thanks

A common problem with our cars.


Solution:
Don't let the fuel get that low ... top off the tank before it gets to 1/4.


Ultimately you'll need to replace/upgrade the fuel pump.

EDIT: when did you change the plugs and coils? Could have a dirty MAF or possibly bad IAV.

fuel pump assembly is kinda hard to get out, ,there is a ''special''tool to get the o-ring off.

once the assembly is out, the fuelpump is quite easy to change.
