Non Starting.

Hi Norbert ,Quick update I've just discovered that with the ignition on with a   test light pin 87 is on ,sorry my poor earhing when I tested before .but no supply to the pump! If it's not a silly question would it be possible to remove the double connector at pin 87 and run two cables outside the car from pin 87 to see if the pump then works ?? The light stayed on while the engine was cranking over. Regards Nigel.

Hi Nigel,
I don't know what you mean with TWO cables from pin 87.

Sure, one cable to the pump from the pin 87 - but the second one has to be ground.
No problem to run the pump using a different connection.

Norbert

Hi Norbert,I've checked again today.Ignition on ECU pin 19 and 16 ,12.50 volts pin 24,  8.67 volts What could be causing the lower voltage? The pump relay, pin 87 is dead pin 86 live and pin 85 clicks when I put the test light in to the terminal. I'm beging to think I will never get the car going .I can see two cables go from the pump relay to up and over ( my drivers side ) wheel arch to the I guess the rear window shelf ,if I'm reading the drawing right one to the fuse and one to the pump.both green and white ,but the actual pump connection under the car looks like one green and white and one brown .Does that mean there is a seperate earth connection somewhere at the back ? When are you coming to London next ? Wishful thinking .Regards Nigel.

Hi Norbert, when you say test pin 16 against 19 pins on the ECU  do you mean connecting each end of a volt meter to each pin  16 and 19 at the same time as I turn on the ignition to test the pump with voltage ie the two second OV mode.? Thank you Nigel.

Yes, Nigel - you will measure +12 V between 16 and 19 for a second or so after switching ignition on.

But you have to find out the reason for the power connection to line 24 being so bad. Maybe you have other problems, too - but it makes no sense to check out everything without repairing the fault you have already found.

Be careful...
don't forget a shortcut could damage the ECU, the harness or other components.

Hi Norbert ,Thank you for your reply .I've checked the fuel pump connection plug terminals ( I took them out ) they look brand new. One cable is Green and White one is Brown.im sure this is a earth cable ,but where it earhs I cannot see. Could the low voltage at 24 and the non pump working be the ECU at fault ? Is there anyway of proving the ECU is faulty without shorting 19 and 16 with voltage? I do t want to damage the system.which is highly likely with my lack of knowledge..Regards Nigel.
