    Unhappy td5 fuel pump issue

    why would a relatively new , 15 000ks old fuel pump give out after starting the car and running for about 15 seconds ? this has now happened 3 times in about as many months and coincidentely when the tank has been roughly half full. in the first instance repeated attempts at self priming failed but 20 ltrs from the jerry can was enough to get it going. the second time a quick self prime routine and all good. last night while attempting the self prime the starter motor wouldnt disengage even after "switching off" , it only stopped cranking when i hit the lock button on the fob. the next attempt at self priming all is fine again. what can be going wrong with the car at the last service there was nothing found re this problem ? all input will be appreciated or is there somewhere in Perth that i can take it too?

    Sounds like you have an air leak at the pump fittings,filter or cooler.

    The pump pick up is submerged till virtually empty. So unless it is incorrectly fitted (should have a very obvious leak if this is the case) It must be sucking air or the pump is a dud.


    The starter motor issue I would suggest is separate and could be a few things. Maybe a sticky solenoid on the starter. Maybe a crook relay to the starter or less likely in the key ign. mech.

    Cheers

    I would check the fuel pump relay under the driver's seat, a couple of members have had the plastic socket the relay plugs into melt a little, and it ends up being a dodgy connection...
    just unplug the relays one at a time, and see if one of the sockets shows signs of burning/overheating.

    I could be wrong, but I thought this was a D2 so no relays under the seat.

    cheers
