Fuel pump issues

[dooce]

My 325 Touring wont start. I've got spark but no fuel.

Following the wiki:

Check Fuse 11- good, even replaced to no avail

Identify and remove the Fuel Pump Relay.
With the relay removed, bridge pins 30 (red wire) and 87 (green/violet) to directly power the fuel pump. Turn on ignition, and check for fuel. nothing changed, even put a known working relay on it and nothing

If fuel is now present, the fault lies in the controlling system.
If no fuel is present, remove the fuel filter and place a suitable fluid containter here. Crank engine. If fuel is now present, replace your fuel filter. I went straight to the outlet of the pump, no fuel coming out.

If fuel is still not present, the fault lies with your fuel pump.
I replaced it with two KNOWN good pumps, still have no fuel

The other section of the wiki:

bridged the fuel pump wiring with bulb and got no light. I also swapped the DME relay with one from a running car.

I know it leads me to the wiring for the pump has somehow gone out, but is there any other option?

This is interesting, and might show a flaw in the Wiki design that needs re-writing.

You can try and power the fuel pump directly from the fuel pump relay socket by running a wire from the battery positive to pin 87. That should make the fuel spin immediately, even with ignition off, so try doing that to rule out the wiring, pump and so on.

If that works it suggests that something is wrong with the DME system, but that should knock out the spark as well...

Once 30 and 87 of the fuel pump are bridged, the pump should run. The ignition does not need to be turned on.
If the pump doesn't run with the bridge in place, check fuse 11 by replacement, and if still no joy, pull the (two pin) plug off of the pump and connect a 12 volt bulb to the pins in the plug.
If the bulb doesn't light, remove the bulb wire from the pin that connects to the brown wire in the plug, and connect that wire from the bulb to a known good body earth (seatbelt bolt).
If the bulb still doesn't light, suspect an immobiliser (or two) connected somewhere in the green/purple wire to the pump.

OK, Ive spent my morning removing an immobiliser. I am getting the light at the fuel pump, but am not getting any fuel from the outlet of the pump. There is at least 30 liters in the tank, so I know that is not an issue. This pump is one that I removed from another running/driving car. Can someone verify that the red wire of the fuel pump should be connected to the green/purple wire? If I had those two mixed up, would the pump now be fried?

[Brianmoooore]

Red should be connected to green/purple, black to brown.
If it's connected the wrong way, it still should run, but won't pump.
I've come across 'good' pumps on more than one occasion that have become faulty if they have been stored dry. I always add a few drops of oil to any pump I store.
If the light at the pump plug now lights at full brightness, but the pump doesn't run when connected, I'm afraid the pump is faulty. Even if it was good in it's previous home, it wouldn't have had long to live.
Try giving the pump a good thump with the live plug connected, but take care if you are working near exposed fuel with fumes everywhere.

Thanks, I ended up swapping it out for another and I am up and running now.
