Hi all! We have been experiencing an issue on site where threads have been missing the latest postings. The platform host Vanilla are working on this issue. A workaround that has been used by some is to navigate back from 1 to 10+ pages to re-sync the thread and this will then show the latest posts. Thanks, Mike.

Hi lux with a high fuel pressure alarm

I've an 08 hilux with a high fuel pressure alarm. It cuts out at low revs when ticking over or at low speed approaching junctions etc. It keeps going when over 40km/hr if I leave it in a low gear and keep the revs high. Put the gauge on it and it can go from 100bar to 300 bar. Changed the fuel pressure sensor but no…

It keeps going when over 40km/hr if I leave it in a low gear and keep the revs high. Put the gauge on it and it can go from 100bar to 300 bar. Changed the fuel pressure sensor but no difference.
Any ideas?

The sensor won't make a difference if it's actually experiencing high pressure and the sensor is correct.
Get the fuel system flushed and pressure tested at somewhere that handles commercials. Probably just 13 years of gack in the lines.
