Timing belt broke how do i make sure crank is on tdc on compression stroke cam gears

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.

First pull the timing belt tensioner then slip the belt off the cam gears. You then need to find TDC (Top dead center). 3 ways to find TDC 1) There are marks on the crank pulley align them for TDC. 2) Remove timing cover and use crank gear mark seen in link below 3) Put the dip stick in cylinder 1 and turn engine until dip stick stops going up. After finding TDC align cam gear marks seen in link below. Now make sure both cam and crank stay in position and slip timing belt back on (you can move the cam gear to get the belt on but make sure the marks are aligned after the belt is on). Last tighten the belt tensioner, I usually use my finger or an extension to get some more tension on the belt. You might have to remove engine mount bracket makes life much easier as the front cover section is TIGHT !!!. Turn engine a few times to make sure you have compression and engine turns without getting stuck. See link below good luck.

Right, so you have two TDC's-the exhaust stroke and the compression stroke Top Dead Center-and both occurr when the crank hits the zero mark on the timing scale.
Always set timing with the number one cylinder at TDC on the compression stroke. How do you know which is which? If you have a distributor, the rotor will be pointing to number one cylinder tower, when at TDC of the compression stroke. If you are on the exhaust stroke's TDC, the rotor will be pointing just opposite of number one .
If you don't have a distributor, look at the valves for cylinder one under the valve cover. If at TDC of compression stroke, both valves will be closed. At TDC of exhaust stroke, the exhaust valve will be open.
You can also find the compression stroke on number one by pulling out the spark plug for number one, and either put a wrench or socket on the crank pulley and turn it clockwise, or use the starter and bump the engine over in short bumps. Put your finger or thumb over the spark plug hole and feel for the pressure to build up. As soon as you feel pressure on your finger, (if turning by hand, pressure will be slight, but you can feel it) you are on the compression stroke. Stop bumping the starter and turn the crank on around by hand until the zero mark lines up on the timing scale-TDC of compression stroke! The exhaust stroke will have no pressure build-up as the piston comes to top-because the exhaust valve is open. On the compression stroke, both valves are closed as the piston travels up the cylinder.

Rotate the engine so that No. 1 cylinder is at TDC on the compression stroke. Check that the timing marks are aligned on the camshaft and crankshaft pulleys. An access plug is provided in the cam belt cover so that the camshaft timing can be checked without removal of the cover or any other parts. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TDC mark on the belt cover. Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover.

Well, since it won't run, you cant check timing with a light. You could try static timing: Bring #1 piston to TDC by mark on scale by crank pulley. Take upper timing chain cover off. Cam pulley should have a mark or circle or dot that lines up with mark on bloick. (Need to make sure you are on compression stroke, not exhaust stroke of piston. How? Best way is pull spark plug and hold finger or thumb over plug hole. As you turn crank (clockwise) with a socket approaching the TDC mark, you will feel pressure build on your finger if you are on compression stroke. Could also have someone bump starter a little at a time, you can feel pressure build on your finger as piston approaches TDC. When it's close, use socket to line up crank pulley with mark.) Now check cam pulley for those timing marks. Valve timing off is often cause of backfires. So is too much gas, but first I would make sure timing is right.

the arrows should face up and there are marks on each gear that should be across from one another in between the two gears{were the gears are nearest each other} al marks should line up again after you turn the crank two complete revolutions. if not remove belt and redo. also make sure cam and crank sensors didnt get damaged/uunplugged

1. remove air intake pipe, and box (upper and lower section)
2. take off timing belt cover
3. take off serpintine belt, and v belt
4. rotate engine to TDC marks line up on crank and cam. camshaft says O^T on it and on the cover behind gear, crank has a notch in the pulley and a arrow on the cover to line up
5. remove crank pulley 6mm allens not the 19mm 12 bolt
6. make sure timing belt is still at TDC remove lower timing belt cover there is 3 bolts and a nut holding it on the nut is by the water pump and the bolts are on on top and 2 behind the crank pulley
7. remove cover
8. mark intermediate shaft shaft right above the crank pulley
9. remove belt
10. install reverse of removal make sure to line up all 3 pulleys cam crank and intermediate shaft or it wont run and depending on how bad it is out of time if you do it wrong you could bend valves

Assuming this is a 2.0 8v your question is pretty vague

Pull #1 spark plug and rotate the engine until you hear air rush out of the cylinder, (plug the hole with your finger if you can), then look at the timing mark, it will be close to TDC

set the timing marks on the crankshaft and the cam marks head to head the marks should be with the cylinder number 1 an tdc top dead center on the compression stroke then adjust the cam so the marks are aligned remember the number 1 piston has to be @ tdc and the crank and cam marks are lined up ok bye for now good luck with it

belt was broken set crank on tdc on compression stroke set timing mark on com set timing mark on oil pump gear? try to start it cranks but wont run check for spark and its gettin but still seems to be out of time starter doesnt crank smoothly replaced starter cranks better but still doesnt run
tried turning crank 1 turn and reinstall belt with same results have any ideas
