Xc70 fuel pump issue

Post by Matt76brown »

Hi there people.

I recently ran out of fuel. Ran tank dry. Went back with a jerry can, 20L.
Tried starting..... nothing.
Cranks but no fire.
No fuel at rail.
Checked 2 pin plug under back seat to pump and have 12v switched feed.
Also have 12v at large plug on top of pump.
Pump not pumping.
Is there a certain pin to check ?
Can i try powering pump of a battety ? Some help would be awesome.
Thankyou

Check you fuel filter.

Sometimes when you run a tank dry a mass of debris gets pushed into the fuel filter and clogs it. The pump may not be running because it detects pressure in the line. The clogged fuel filter prevents the fuel from reaching the fuel rail.

You may of burned up the fuel pump. Fuel does double duty as the coolant for the pump.
You can try hooking 12V up direct to the pump motor. Just keep in mind it needs to be keep cool.
