Re: put in a new timing belt, how do i set the timing
If you are sure you set the marks right, it should not have changed anything else. Did it break and you changed it? If so there maybe more damage. Also check to see if you have spark and check cam position sensor on right top cam cover. Good luck and have a great day.

line up the marks on crank shaft gear arrow to arrow, the front cam gear the mark goes to the middle on the rear cam gear the mark goes one notch below front gear mark they line up when the tension is put on belt.
timing belt replacement is a little tedious. first remove negative battery cable and move away from battery. remove serpentine belt and set aside. on models with A/c remove compressor and set aside, then take mounting bracket off. going through the fender well behind the tire remove the lower pully with a torx wrench. remove the cover for timing belt. it goes all the from top to bottom. this is when you line up the timing marks to make it easier to reassemble. There is a belt tensioner on the timing belt toward the rear of car. loosen and the belt will come off. When you put the belt in and set the tensioner make sure the timing marks are aligned. clean the old gasket off the cover and put in a new one to avoid leakage.
If the belt keeps jumping, I would say you have a badly worn sprocket or the belt tensioner needs checking, it may need a new tensioner or your procedure for tightening it needs to be checked. If no mark for the idler, then just put it at the 4 o'clock position, as you are facing it.
You need to purchase a Haynes Manual or better. They are very common in your nearest chain part store. Like Autozone, Advance, Napa. More than likely you will have to set the crankshaft at TDC. "top dead center" and allign the two marks with the cam shaft! Watch when you put tension on the belt it will move the camshaft sprocket! And throw it back out of time.
confirm you timing belt marking at the engine before you start the work. then dismantle all the belt one by one until you reach the timing cover. mark the timing mark again. then start dismantle the timing belt set. after all the belt are out, open the water pump and start to put back the new part by using reverse order from the opening list. make sure the timing marking are the same as you check at the first time. before you start the engine, make sure you turn the engine 2 or 3 round and make sure no part are hitting. good luck.
The crank has got to be at TDC, with the marks lined up, the cams have to be lined up to their marks, then the belt will line up, If it doesn't line up, You will be walking home. If you have the old belt handy and the marks are still visible, compare them to the new belt, make sure they are the same. Pull the pin on the belt tensioner and you should be all set. Hope this helps.
they should be marks on the cam gears take the #1 plug out take a long screwdriver put in cyld. hole have someone turn crank with wrench till it gets dead top and check the mark on crank then put belt back on start befor u put back to gether should start
it was good to check how timing is before you removed old belt.
anyway first before you fited new one rotate the engine by hand look front crankshaft timing mark,
put piston number one should top dead center look cranshaft mark.when you done.
second step is to set up camshaft check timing mark on the camshaft follow the marks fisr cylinder.
