Hi Dan
cranks or does not crank fast,??? the starter motor spins the crank shaft fast, 300rpm in fact and must first.
or it cannot be started , my Wangler 6speed ,M/T push starts and gravity starts too. but no the A/T box fitted Funcargo
1999 to 2005 not one in USA at all
one answer fails to crank, battery dead or A/T not in park or neutral.
2nd answer, cranks fast but will not start.

• spark dead.
• fueling dead or bad fuel. wrong fuel class, diesel in to petrol ?
• fueling too much flooding , crank with wide open throttle WOT.
• engine bad, cam belt slipped or snapped at 100km and did.

You didnt specify what you need to torque. Headbolts,cam,crankcase etc.....

Sorry we do not have this type of information about parts cross overs here.

Here is a complete listing of all makes and model engines, it is a FELPRO pdf Look your year and make and model up in the booklet
http://olybrake.com/pdf/fel_pro_torque_specs_guide.pdf

Most auto parts stores should be able to print off a spec sheet for the torque specs. They will need to know the year and model it came out of if not original engine.

belta.
what year.?
2SZ-FE , toyota?
this is in the FSM.
where to buy part related.
