Non Starting.

Hi Norbert ,Thank you for that ,I will try and look  at the cables for faults ,there is a triple plastic clear blocks fitted to my top servo ,I've take this apart to have a visual check of the wires they all appear ok.Yes I have a BMW wiring diagram, but I'm getting out of my depth with the electrics.A friend is paying me a visit next month and he has good knowledge like you of this system, so I hope between you both I will get to the bottom of the problem..The weather is horrible here so not missing much driving.Regards Nigel

Hi Norbert,I tried connecting a seperate ground wire from the pump connector under the car to the chassis, No sound from the pump.I then removed the ECU wiring and connected my volt meter with two needle tips and the bulb taped to the meter ends and the bulb lit up and was showing around 10.5 V this maybe because of my poor connections. Then put everything back together now ignition on main relay clicks but the pump relay is quiet .I give up .How can I send a picture ? I cant figure out the icons above this writing..I want to take from my libarary ..Regards Nigel.

Hi Nigel,
you have to reduce pictures to insert them.
There are special ads for mobiles to do this, under Windows I use the free image resizer.

You can add Attachments (like pictures or other files) below the text field.

Thanks Norbert, Quick question do you think the voltage could be OK? Does this prove the ECU s are probably OK? Best Nigel.

10,5 Volts are not sufficient for a proper operation, but should not lead to a total misfunction.
All Voltages, cables, sensors and so on have to be checked before one could  say anything about the ECU function.

Norbert
