    Hot wire IP , so im sure if its IP or electrics ??

    Hi, Zd30 Di [2006]
    Died while driving, wont start.
    Noticed when i turn on the key there is a ticking/buzzing noise coming from IP area, lasts for bit less than a second, then stops. I believe it is possible hotwire the IP thereby ruling out any electrical control problems.
    Any help greatly appeciated
    Thanks David

    David you have five or so different threads you've created around the same issue. It would be better to keep all it in one I think. then if you resolve it, its easier for members to track if they are chasing the same thing.
    You have error codes as stated in one of your threads.

    Here is the list of codes and their meanings.
    Fault codes
    0102 Air Flow Sensor
    0103 Coolant temp sender
    0104 Vehicle speed sensor
    0203 Throttle pedal switch
    0208 Cooling Fan control
    0301 Engine ECU
    0402 Fuel temperature sensor
    0403 Throttle pedal position sensor
    0406* Intake air volume VNC system
    0407 Crankshaft position sensor
    0502* Battery voltage
    0504 Auto Trans communication line
    0701 Injection Pump –cam ring position sensor
    0702 Injection Pump –TDC pulse sensor
    0703 Injection Pump communication line
    0704 Injection Pump –spill valve
    0705 Injection Pump –ECU
    0706 Injection Pump –spill valve
    0707 Injection Pump injection timing control
    0802 Engine ECU
    0804* Engine ECU
    0807 Stop lamp switch
    0901 Engine ECU
    0902 Engine ECU relay
    0903* Engine ECU
    0905 Intake air pressure sensor
    1003 EGR volume control valve
    1004 Injection Pump –fuel cut out system

    * These codes do not illuminate the Check Engine warning lamp.


    I had 0703 on my old ZD, as mentioned and it meant the pump was terminal. FUBAR, no go, no worky. Unfortunately you will have to replace the IP. There is no point in wasting your time trying to repair it yourself. These pumps have a PCB mounted in a small housing on the pump. I dare say the PCB has had a melt down. Literally. Fairly common issue it used to be. Ring up a pump specialist who sells these pumps and get their take on it. .

    Lastly.
    Where are you located? I know someone who has a working pump he might be convinced to sell. *cough* @rusty_nail *cough*

    Thanks mudski for your reply. I will take onboard future posting habbits as you advised.
    Maybe i just have to face the bitter facts and pull the IP. My reluctance was mainly due to false hope, and thinking what if I change out the IP when say the only thing wrong was shut off valve staying closed ?
    I am in SA and yes I suppose I am looking for another IP.
    Thanks.

    Take it to an expert mate. Get them to diagnose it properly for you.

    Unfortunately I dont think there is a cheap fix here. Either replace the pump with a known working second hand unit, or a reco'ed unit.

    My thoughts are that probably none of it will operate like it should unless the car is running. I wouldn't expect fuel to be pouring out of the return as it sits.

    Seriously mate if you don't believe the codes take it to someone to have a look at it. If the pump is indeed gone to the gods they'll tell you quick smart.
