where is the fuel pump relay please

rr wont strt on petrol but will run on lpg ..i can hear the pump makin a noise but no go ive checked fuses 39 and 12 they r fine ...is there a relay anywhere else please

ive checked the fuel rail and nothin is comin out wen i turn the key ... can any1 help?

Which model RR?

If its a RRC EFi & you can hear the pump running is there fuel in the tank?
Is there a blockage at the pump end?
Is the tank breather pipe clear? (undo the cap & hear if there is an inrush of air)
Is the pump pickup pipe in good order & in the fuel? (If you've replaced the fuel tank & not adjusted the length of the pickup pipe it may be above the fuel level despite the gauge saying you've got 1/4 of a tank left. Now how do I know that could happen:doh

ive posted on yr other thread if ya wanna use that one or this let me know cos i aint typing twice!! lol!!!

its a 1996 p38 4.0 v8
il chek the pipes now
