Owner of a 2006 xc90 4.4 v8 car was driving fine ran low on fuel one day wouldn't start I put some fuel in after a couple tries it started I have also been using it to jump my other car and now my battery is dead and when I try jumping the xc90 it cranks with no start showing pcm code but showing prior to problem have changed spark.plugs and coil still not starting at a lost not sure if I should change alternator, or fuel pump and I cannot locate pcm

 

spray starting fluid in the intake. that will tell you if it is a fuel issue. changing alternator would make no sense.
