Hi all,

Having a bit of an issue with my 2014 L405 supercharged autobiography.

I was very low on fuel, stopped to fill her up, and got back in and tried to start. It kept cranking and cranking before firing up. Seems like fuel was not getting to engine.

I ran the codes on the IID Gap tool, and got the below codes. I have since fitted a new fuel pump sending unit (under the rear seats).

I also attempted to replace the fuel pressure sensor on the fuel rail in engine. (US passanger side/UK drivers side). The replacement was leaking fuel out of the electrical connector end, so had to reinstall the original one which does not leak.

If I pump the accelerator when cranking it eventually fires up, then drives perfectly fine. As soon as I shut it off, and try to restart its the same problem. Please help as I want to get her back on the road.

Most 405's this side of the pond are diesels..

You may have more luck searching on Jaguar forums both sides of the pond, there should be far more info..  Pete
