Hi everyone, I have a non-starting problem with my P2 V70 petrol car. There is no pressure on the fuel rail, if I remove the valve core and crank no fuel comes out.
I have replave the relay and checked the 15 amp fuse.
Can anyone tell me how to check the pump before I pull the car apart trying to get it out?
What colour are the plugs under the tack seat? I see a geen plug with two wires next to a bigger grey plug with about ten wires.
Should the pump run when the ignition is turned onif the fuse and relay are good or does it need a 'fancy' signal from the ECU?
Sorry for all the questions but any help would be greatly appriciated,

    Do you hear the pump prime itself for a few seconds when you turn the key to ON (without starting the engine)?

    If you had a wiring diagram you could probe the wires (be sure to seal them back up).
