which engine? 1998
must we guess that and tell you wrong......
here is the line up. pick one.?????
to fix any engine or buy parts you need to say which one, (1/2 the posts here dont.. and go nowhere)
3.2 L 6VD1 SOHC V6 Gas. my guess 1st 3 here.
3.2 L 6VD1 DOHC V6
3.5 L 6VE1 DOHC V6
3.0 L 4JX1 TD I4 (diesels x2)
3.1 L 4JG2 TD I4
once we know that we can look in the FSM book
or at isuzu dot com and read the parts pages.
and see all parts on car or engine.
many oem parts sites have no photos , so avoid them...
one of the better sites, have no photo as seen here.
(a 1/2 baked job there... huh?)
crank sensors can be in 4 places.
1: front of crank at pulley
2: near center of crank, omg. yes.
3: at fly wheel at bell mount.
4: behind fly wheel remove transmission first.
now you know the places.
and if you look carefully deduction answers this.
none on bellhousing;
none on front pulley.?
leaving what, the 2 harder ones.
the center sensor can look like knock sensor.
so.... you need to read the FSM for that.
or try to buy the part using the shape of it proves what it is or not. (it does in this case)
so ill guess, (silly huh?) 3.5L v6 engine. option
here is that sensors. below.
so its not the behind flywheel ,see why?
its mid crank, or front or bell sensor..
so ill google for you...
its not on the BELL.
THIS (MID CRANK AND A PHOTO OF IT)
i did all this in 5min work....
and was posted here before, if you search for your unstated engine.
see photo 2
that be it. on the 6DV1 engine.
