2002 Mazda 626 v6.If you have the timing marks on the cam drive gears aligned and the motor at tdc on the number one cylinder on the compression stroke will your motor be in time?

Why don't you try and along them can you do it?? If not you need the holding tool that allows for the proper alignment of the timing belt gears on this engine.

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.

set mark on crankshaft to TDC mark on timing cover. set mark on cam pulley to align with mark on head .if more than one mark on pulley rotate by hand till exhaust and inlet just rocking then align closest marks .

Check to make sure you are TDC compression stroke on number 1 cylinder.

Check to see that all your timing marks are still in line at TDC No1 cylinder, compression stroke.. Sounds like the engine is trying to push against itself.

Hi Marina,

These diagrams may be a little hard to see, but the cams have a mark that align with the raised "V" on the rear timing cover and the crankshaft pulley has a notch that aligns with the mark in the 12 O'clock position on the oil pump housing.

I cant find a picture to show you, but if you rotate the engine until #1 is at TDC there should be a timing mark on the crankshaft gear that lines up with a pointer and the cams should have marks that line up also. Most of the time there is a molded line in the cam gear and it lines up with a molded slot in the plate behind the gear at the 12 O'clock position.

as long as it looks like this...




however, this only give you base engine timing

ignition timing is done with sensors and computers

I can think of two possible causes:
1 - Assuming you are getting spark at the plugs, the distributor may be reinstalled 180 deg off.
2 - Unlikely but - Assuming you are getting fuel into the cylinders, the fuel injector connectors were reinstalled improperly and are firing out of sequence. If you are not getting fuel into the cylinders, it's something else.

re-install belt, lining up the timing marks, crank to TDC #1 cylinder, cma pulleys have marks on them, line them up to the index marks as well. If you have a drive wheel in the air, you can pop the car into 5th gear (make sure it's chocked!) and rotate the wheel to turn the engine for alignment, etc. You can put a wrench/socket on the cam bolt to align it as well.
