both my fuel pumps aren't receiving power, the fuel relay is but the pumps
are not, i really do not understand why

Your relays on that model are on a panel inside a cupboard door that becomes visible above the driver's right knee when you open the driver's door, right? A pig to get at, right? You say that you have checked the relay. Have you managed to detach a control wire while checking the relay? Have you managed to detach a wire from a pump while changing the pumps? Can you do a rough jury-rig test by getting battery voltage onto the pumps with a long wire (after disconnecting the relay)?

Why did you change the pumps if the relay is not providing power. Sounds like you've diagnosed a faulty relay, when this is a common fault. Pull the cover off and check the relay PCB.

ive tested both pumps separately using a battery and they both work, the relay behind the center console clicks when the ignition on, i bypassed the relay with a wire so the pumps should work when the ignition is on, still i have no power at all at both pumps

because i thought that the pump had died

somehow i managed to get home with it spluttering and then it eventually dieing on the drive.

OK, that's the same relay location as the 940s - behind the ashtray? Totes different from my 760T.

That make is pretty simple to pull the relay and try a new one.

yes the relays are behind the ashtray facing towards the drivers left leg,with a orange screw securing it

Do you have a fuel shut off on this car?
The type with a button under the bonnet to reset after a bump?
Just a thought?

The last 3 fuel pump relays I've looked at have been faulty. All 3 had dry joints on the circuit boards inside. The most recent one was the worst, with over half of the joints needing resoldering.
