G60 to VR6....Fuel pump not coming on?

[C. Will Corrado G60 2 0]

Hi,,can anyone help me get my VR6 running?

 

I've gone for a 2.8 VR6 (coil pack) conversion and have used the donor car loom. My problem is the car is turning over but the fuel pump is not coming on.

 

Can anyone please help?

Probably no signal from the ECU to the fuel pump relay. Have you left the diagnostic socket available? Have you used the G60 or VR6 fuel pump? Not that it affects it running; I’m just interested to know.

Crasher, Yep, it's seems like there is no sign from the ECU. The diagnostic tool is available, but didn't show anything. I had replaced the G60 pump with a VR6 pump both as the G60 one failed about 8 month ago.

Using VAG-COM you can drive the injectors which drives the fuel pump relay. Some simple tests. Remove the fuel pump relay (12 with 167 on top) and use a multimeter to check for a permanent live power at socket 6 on the relay plate vacant fuel pump position, and then check for permanent earth continuity at socket 2. Next, check for continuity between socket 4 and position 1 at the fuel tank plug on the red/yellow wire. Now check for continuity from socket 3 to the ECU plug socket 6. Of course, you should also check the 20A fuse at position 18 to make sure it isn't blown. If this all checks out, refit the relay but leave the ECU plug off. Turn the ignition on and connect and an earth wire to pin 6 on the ECU harness plug and the fuel pump should fire up.
