Hi guys....

How are you all, really hope you can help, I'm trying to help a freind out, he's got a 2.7 2007 range rover sport.... it keeps going nuts, goes into limp, dash lights up like a xmas tree, putting DTC p0088-00 fuel pressure too high.... I've data logged it, on start up, its smooth, but after about a min it goes erratic... as soon as it jumps above 4k bar, it puts the lights on and logs the DTC....
So far, we've changed the fuel filter, rail sensor and the HP pump....
Have also overlayed the wiring from the rail sensor 2 the PCM....
I've gone thoug the wiring the best I can and can't seem 2 find anything....

Hope you guys have come across this....

Many thanks.... wayne....
