    Re: terrano dying after a few k's

    I fitted a Hansa electric in line fuel pump and also fitted a VF Cab fuel filter

Time for bypassing tank altogether, tie a Jerry to the bullbar or put in passenger footwell. Take a hose from jerry directly to the ip thru a small inline filter. Leave return alone for purposes of the test. Report back when you have done this.
      Edit
      I now see Tony has already suggested this.
      Are you thinking there is a restriction from tank to injection pump....what would cause this any ideas anyway will give it a go mate cheers but it may be a few days as work commitments take priority keep a look out.. thanks. could fitting a cheap inline pump as Bitsathis has suggested be woth a shot I can get one pretty cheap locally. Thanks fellas for your help I have a soft spot for the old car and I would hate to have her end up in the scrap yard

        Is the IP mechanicly controlled , cable from accelerator, or electricly controlled VF zexel pump, throttle position sensor and black plastic box on top of IP withwires going to it.?? If its electronicly controlled it can be one of several sensors or bad connectors.

          dagwill, I am pretty sure it is a mechanically controlled IP. I can't recall for sure but I have an impression it is an inline pump.

                Be very thankfull its a mechanical pump, and not the later electronicly controlled, witch are grt when they are NEW but a nightmare as they age. On the older Terranos access to the fuel tank is under the matt in the rear luggage area. Remove cover, disconnect fuel lines, dust off top of fuel tank, remove cover with fuel pickup,guage. Some have a filter on the bottom of the fuel pickup. If its not that filter at least you can blow through the fuel lines and know theres no blockage.

                      Yes it would have a mechanical VE type pump made by Zexel under licence from Bosch. Dagwill has suggested the fuel lines were prone to corroding so rather than adding a pump to possibly the dodgy pipe best to try the jerry can method to eliminate the fuel line for the moment. If it turns out to be blocked steel pipes then best to replace them. I'd try the airline some have suggested.

                        Re: terrano dying after a few k's

                        Well I have managed a stop gap repair.....I fitted an inline pump just prior to the filter and it worked , car has been driven 30 k's and no problems with it stopping. I must admit I am still looking at trying the jerry can idea but time at the moment is tight. I pulled fuel pickup out of tank and thee is no filter on the end so it couldnt be a blockage there. Must be the IP getting tired and not holding pressure. Is it right to assume that running pump long term will eventually cause issues? I just bought a cheap square facet style pump so I will eventually buy a better quality one. I must admit to struggling getting an air tight seal on pump outlets but will play around with thread tape. Many thanks ta all for your inputs its been very much appreciated. HAVE A GREAT XMAS EVERYONE

                          Good to hear you have some progress, sounds like your on the right track. If you have just bought one of those little square pumps,,,, an idea for after Xmas when the rush is over. Disconnect rubber hose from fuel tank, with a couple of extra bits of hose, plumb the pump sucking from tank pipe then into hose you just disconnected ,power up pump and leave it 1/2 hr then you can do a visual for wet leaks along fuel system, showing possible air leak intake spots. Anyway good news

                              Artrix,
                              What he is suggesting is that you temporarily relocate the fuel pump to the fuel line leaving the fuel tank. Then run the pump for at least 30 min to check for fuel leaks from the fuel system plumbing. Any fuel leaking out would indicate a place where air leaks into the system when the IP is working without the added pump.
                              You may not have any fuel leakage from the system though.
                              Once finished testing, return the pump to it's current location. It obviously helps the IP in its current location.

                                Hey Tony,

                                out of interest I have my pusher pump in both the Cruiser and the Mazda down near the tank outlet. I went to the effort of putting it there so the line is constantly pressurised, and always air leak free. Somebody once told me that fuel pumps are generally bench tested with a positive 2 PSI or so of fuel pressure. it would be nice to think that my pumps are providing this, although I never bothered to check. I doubt that there would be 2psi when the car is running, as I reckon the IP would draw almost as much as the little pump would provide. Since fitting down near the tank I have never had an air leak issue. prior to this I nearly sold the car in frustration.

                                I power mine form the ignition key, so it is always running. It also makes purging the filter bowl a breeze.
