- 2012 E3 clubsport
Hi all,
I have replaced my ECU and the “engine bay loom” that goes between the ecu down the chassis rail to abs and through the firewall to drivers side kick panel.
Ecu was new
Loom is out of a 2010 clubsport from a dismantler who has insured me will be exactly the same.
I have the it cranking over but the fuel pump isn’t priming/ pumping.
I have 12v to the fuel pump control module (under battery box) and 0v coming out of it until…
I have put a scan tool on and tried to turn fuel pump on, pump clicks for a split second and then nothing.
On output wires of fuel pump control module there is a spike of voltage then drops to 0v almost instantly.
Please help.
Was thinking the signal wire from ecu?
Fuel pump can be run up by supplying 12v directly to it by another source.
