Vauxhall Combo C 1.3 CDTi 2005 - Non start, no feed to lift pump in tank #

Posted by Chris Shelton on December 21, 2009, 5:56 pm

Year of Manufacture *: 2005
Engine Code or CC *: 1.3CDTi
( Optional ) ECU Type: Magneti Marelli 6JF
( Optional ) Scanner Used: Solus Pro

Hi all,
Called to this van today, it had been towed in by the AA.
No start, no feed to lift pump in tank, read codes, 1 undocumented and another for EGR sensor.
I looked at auto-data for fuel pump relay position, but it only list's petrol relay position.
No owner's manual in van.
Can anyone tell me the location of the pump relay please.
I ran out of time today, and have to return tomorrow.

Any help would be appreciated.

Returned today, checked relay, feeds and pump, relay not being switched by ECU, suspect ECU faulty so being taken to main dealer.

Thanks again Lee for the info.

sorry mate but a bit to quick for me send to dealer. Did you check all of your process data? Rpm,cam-crank synchro? And the fuel shut-off valve if there is any.

From looking at wiring diagram the main engine control relay puts a live to terminal 86 of fuel pump relay and terminal 85 is the ecu switched earth.

Just a thought, does your scantool activate fuel pump. Have you actually fed your own supply to ful pump from relay terminal 87 to see if pump runs.

Thank you for all the replies and tips.
I did try activating the fuel pump with Solus, but no drive from ECU.
I bridged the 30 and 87 connections of the relay and the pump ran, also earthed the 85 connection on the relay and pump ran again, proving feeds and relay OK.
The garage owner where the van was recovered to did not want to get involved any further, and this is why it was sent to the main dealer.
ECU's are supplied blank and have to be programmed, I do not have tech2 etc.

(immobilser relay???) Theres no such relay!Theres a terminal 15 relay that powers immobiliser but it also powers aircon engine insrument wipers brake lamps reverse lamps cigarette lighter alarm and airbag,The only way to find this problem is to get wiring diagram a find fault not throw parts at it.
