Could someone please guide me in the right direction for this problem. I have a 99 land rover discovery. We parked it and it was running and now it would turn over but wont start. the codes p1843 and p1842. i can not hear the fuel pump come on and wont start please help thanks

 

hi..

check the inertia switch... when is activated.. the fuel pump is cut it off...
check the fuel pump fuse...
try to start it on N- neutral....
