NOTE: On 49-State, and all automatic transmission vehicles, it is not necessary to align auxiliary shaft sprocket.If vehicle is California Emissions Certified with manual transmission:
Install Synchronizer Positioner T93P-12200-A into synchronizer.
Rotate auxiliary shaft sprocket until the synchronizer shutter is against the stop, and the notch of the tool engages the notch of the synchronizer bowl.
Install timing belt over crankshaft sprocket . Then, proceeding counter-clockwise, over auxiliary shaft sprocket and camshaft sprocket.
Loosen tensioner adjusting bolt allowing tensioner pulley to press against timing belt.
Remove tool from synchronizer.
NOTE: When performing the following step, do not rotate crankshaft counter-clockwise as timing belt may jump a cog, putting camshaft or auxiliary shaft out of time.Rotate crankshaft two revolutions clockwise.
Bring crankshaft slowly, without stopping, to number one cylinder firing position (keyway directly up).
Recheck timing mark alignment. Repeat steps if timing marks are no longer properly aligned.
Rotate tensioner assembly against bolt with torque wrench up to 41-45 Nm (30-33 ft-lb) and tighten adjusting bolt.
Tighten adjusting bolt to 35-45 Nm (26-33 ft-lb).
Tighten spring pivot bolt to 40-55 Nm (30-40 ft-lb).
Install the crankshaft belt guide.
Install the crankshaft position sensor onto the dowel pin and tighten the two longer bolts to 8-12 Nm (6-9 ft-lb).
Adjust crankshaft position sensor air gap. Refer to Section 03-07B or Section 03-07C.
Install outer timing belt cover as outlined in this section.
Install spark plugs .

Recheck your timing marks. Sounds like valve timing is off. Check compression it needs a minimum 90 lbs to run. Bet you money the timing belt was put on out of phase.
