Question about Cars & Trucks
Had to replace water pump and in doing so had to take out camshaft pulleys and timing belt etc. Putting timing belt back is a task in itself but when i put everything back and i mean tdc and giving it atleast 2 revolutions and it all lining up on tdc again taking it for a test drive was another story. timing belt jumped i dont know how but it did and of course loss of power and backfiring in airbox. The car is already missing scanner pulled up misfire cyl 6 but, thats something different or is it. could the misfire cause the timing belt to jump a tooth? the camshaft marks are lined up but the crank shaft pulley is the one that goes off by a tooth so I'm fustrated.
Remove the t belt and reinstall it. Sounds like you were a half a tooth of on the cams wich would put you a tooth off on the crank. A lack of power makes sense with bad cam timing a s could,very well throw a miss. The misfire did not cause timing to jump

SOURCE: putting belt back on pulleys
Your owners manual/label in engine compartment will have a diagram for how the belt runs. There will be one pulley that has a spring tensioner. This pulley keeps the belt tight and is used to install the new belt. Depending on the vehicle, these can be easy or very difficult to get at. The pulley or arm attached to the pulley will have a square hole of some means of inserting a tool to allow you to release the spring tension. I typically will install the tool and verify that I can get the tension off the belt before starting the process. Once I feel comfortable that I have the correct tool, I will release the tension and remove the belt. Then reinstall the new belt per the diagram. You will have to keep the tension off until the belt is in possition. I have found out that it is easiest if you put the belt on all the lower pulleys first and get down to one remaining pulley (top side of the engine so you have good access). Now use the tool inserted into the spring tensioner and move it until you have enough slack to get the belt over the last pulley, once in place release the tensioner. I typically have the belt over the tensioner pulley, and use the alternator or steering pulley as last pulley because it keeps your fingers out of the pinch points. There are some special tools you can purchase at Sears to assist, but I typically use a ratchet or wrench for this work. Sometimes a third hand helps out.
