Exclamation No power to fuel pump.

Fuel pump stopped working so i replaced it today with a new bosch. Much to my surprise there is still no power. I checked the EFI and COR relays and they are fine.

I know it's a totally different beast, but on my 22re the fuel pump ONLY gets power if the engine is already turning (even if only by the starter). As i understand it, it's a safety mechanism; if you crash and your engine is dead, you don't want fuel still pumping. I don't know if your engine has something like that, but you might check it out.

Have you checked for 12v at the pump? I know that on the 3vze the fuel pump power goes through the vafm.
