My 1997 Disco 1 is throwing 3 codes!
p1193
p0158
and p3999
from what I have been reading the third is a generic code, but the first 2 are both oxygen sensors, although I have do have another problem!
my disco doesnt want to start, no battery or alternator problems, the starter seems to be just spinning, i thought maybe the fuel pump is beginning to wear out? any help on a good place to find one or if anyone has any extras floating around?!?
Thanks!!

 

not really posted on the correct section of the forum.

are you sure its the fuel pump? what pressure at the rail? what voltage you getting at the battery?
