was just asked to look at a 2004 rodeo code p0300.Has new fuel pump ,one new coil pack ,heads redone with new gasket set,new timing belt and waterpump.Mechanic also drilled holes by each cat.After he did all that same code same problem which is the code and no power at all.Any help would be appreciated haven't done anything yet as battery was stone dead.Charged battery cranks but no start no evidence of fuel on plugs but dont know if there is any other issues as snow is starting to fall and car has sat for a month.Any help would be appreciated .Thanks

 

if i'm not mistaking the code stands for random misfire. I had that problem, changed the plugs after reading about my 2000 V6 calls for Denso K16PR-P11 and nothing else (since they are also being used by the computer as sensors for the combustion quality).
That took care of the code.....
as to the no-start condition - with no fuel on the plugs after cranking, that's some good evidence to work with....
