Is the crankshaft supposed to be pointed at the 3 o clock position, i have a 2000 isuzu rodeo 3.2 looks exactly like yours there are metal marks on the cams that show where they should be, also if they are out of time apparently you have to crank the driver's side cam to 3 o clock and then crank it the 90degrees to the timing mark, i believe that's only if its out of time I'm doing my water pump changed the pullies tensioner belt etc and put everything together with out doing that turn to 3 oclock and then use 14mm socket to turn her clockwise another 90degrees so she's on time.
I'm currently working on on one that was brought to me the cam is probably off a tooth or 2 on the passenger side it backfires out the intake think that's my problem and doesn't start
