Default Re: 1999 2.5L Timing belt snapped, replaced it, won't start

Tnx White99 ... rolling now, last question pls ... other than aligning the marks - diamonds/arrows - once belt installed, how do I check syncronization before re-asembly. You mentioned being 180_o off, after you attempted to crank, did u figure it out? tnx in advance for your time.

Swan2012,
Aligning the marks should put you right in time, Camshaft should be triangle to triangle (the mark on the pulley is hard to see) but the triangle should be close to 4 O'Clock and the Diamond would be between 12 & 1, the Oil Pump Pully has the same marks, but you need to match diamond to diamond, diamond will be nearly 12 O'Clock, and the crankshaft keyway should be at 12 O'Clock and there is a dot indented on the crank that matches up with a notch on the back cover

see illustration on this other thread.. posted by Rangerman49

if your 180 out on the cam, you'll know as soon as you turn the key over, it sounds terrible, may backfire or sound odd.. because it would be trying to fire on an exhaust stroke.

I think my problem may be the crankshaft position sensor - in process of changing that now --

----------

also, make sure you put the belt on counterclockwise starting with the crankshaft, then oil pump, then camshaft, and over the belt tensioner last.. be sure to keep slack out of the belt, watch your marks when you release the tensioner to be sure it doesn't move your marks. once you have the belt on tighten tensioner and rotate crank 2 revolutions clockwise (direction of normal operation) and see if your marks are still lined up. If they are, you should be good to go, if they are off a mark or two, it may of slipped when you released the belt tensioner.. in that case, just try again.
