Hello.
I think I just diagnosed my WUR as faulty, preventing my car from starting.

Electrical system/relays etc all good.
WUR has 36 ohms across its electrical terminal (the wire resistor wound around the bi-metallic strip in the WUR)
12V confirmed to be applied to the WUR when I key on.


Now, I am waiting for adaptors from eBay to allow me to connect my fuel pressure gauge to the car. The only adaptor I do have in the meantime, is one that fits the M8 thread of the fuel return line on the WUR itself.

1. This return line is sending 58psi of fuel pressure back to the fuel tank, whether the WUR electrical plug is connected OR disconnected.
2. Leaving the pressure gauge in the return line connection, acting as a “plug” (No fuel can return to the tank) the car cranked and fired up! Hurrah!

So are my checks 1 and 2 sufficient to know I now must buy a new WUR?
They are not cheap so need to be sure I don't waste money!

Thanks.
