Cam timing with no colored links on chain!!

The marks on the chain are for your convenience i.e. no need to count links between crank and cam(s).

The chain markings shift depending on the number of links in the chain and number of teeth on the crank and cam gears, but the number of links (rotational distance) between crank and cams remains the same.

Once you turn the crank it it may take dozens of revolutions to sync back to the marks on the chain, unless you reverse the same number of revolutions.

So if you want to recheck timing after multiple crank revolutions, you need to count links from crank to cam and cam to cam or redo the timing procedure.

Think of it this way... you could stretch a chain around the moon and timing will be good but it will take hundreds of thousands of revolutions before the marks return to earth and likely still not in sync with gear marks.

In the old small block days no one counted links because crank and cam gears were adjacent, in the same planes and timing intuitive.

The 2.4 engine in the G6 uses a timing chain. On the chain there are 3 links each one a different colour to all the other link in the chain. On the face of each Cam sprocket and the Crank sprocket there is a notch or a groove mark. When the engine is at Top Dead Centre (TDC) on Cylinder One each coloured link will line up with a notch. **NOTE** All 3 must line up to be at TDC.

50 causes, want to guess wrong 50 times
its not a dead started. nor dead battery. nor bad alternator at this point.
the word is start, not turns over, the starter motor and engine both turn over called spinning, he engine then spins(turns) and then spark burns the fuel so spark is first.
not start using jumper cable car top car other car running,
like the AAA auto club tow man does 100 times a day.
?
if dead , check spark, fuel can not burn lacking good spark\
we test all spark plugs for strong spark
if you did the chain wrong the cam is time wrong and now cam and spark are timed wrong. and compression is 1/2 normal and is now 3 ways wrong. see? chain wrong cause 3 wrongs
and on modern cars newer, the PCM sees CMP and CKP out of sync and pcm then cuts spark and cutting spark cuts fuel tool
so now 5 ways wrong
your post did not say at what point that work made engine dead.
your list if events seems wrong. time
runs
new chain
dead , is this it?, seems so to me but I can not watch you mess up.

the chain can not be just thrown on
and TDC happens 2 times on 4 cycle engines
the correct TDC must be used per the manual.
some use #1 firing other cars use #4
or just match marks crank and cam,

L61 engine with chain balance shaft.
cam chain, shows 7 tools to do this job , ouch
step 22
Rotate the crankshaft in the engine rotational direction clockwise, until the No.?1 piston is at top dead center (TDC) on the compression stroke.
ahhhh yes very tricky timing settings to avoid piston valve hITS
steps:
Rotate the crankshaft in the engine rotational direction clockwise, until the No.?1 piston is at top dead center (TDC) on the compression stroke. set chain color cap to crank cog mark
then at cams, 2 more chain caps at:
set EXH mark cam to chain colored cap

1. Using the dampener, rotate the crank so that the mark on the timing chain drive sprocket is at 5?o'clock position.
2. Set the crankshaft to 60?degrees before the top dead center.

position the exhaust camshaft with the offset slot to 2?o'clock position.EXH mark.
Position intake camshaft with offset slot to 11?o'clock position..
INT mark
all; 3 marks must be correct or bend valves you will
if set wrong DO IT AGAIN> now, keys in pocket.
this is an INTERFERENCE engine,
use DUE RESPECT OF THIS or huge damage happens./

First, DO NOT start the engine if the mechanical timing is wrong! My next obvious suggestion is to get it to a good mechanic and get them to sort it out for you.
I'm assuming your refering to the Mechanical Timing? Mazda use an 'Interference' engine so read this all the way through BEFORE doing any work. An interference engine means the valves will hit the piston face if the mechanical timing is even slightly out. That is why you don't start your engine with the timing set wrong. It's a VERY expensive repair.
Start from scratch. Remove the chain from the CAMs and cable tie it to something on the top of the engine to stop it disappearing out of sight.
Turn the Crank to about 10 to 15 degrees past Top Dead Centre (TDC). This is to move the pistons away from the valves so you can set the Cam timing marks. Set the Cam marks first then turn the Crank BACK to TDC. As long as the chain marker on the crank sprocket is lined up correctly the Cam chain markers should be correct.
Once you have timed everything into place use a socket and ratchet to turn the Crank pulley bolt Clockwise 2 full rotations. The timing marks should return to the correct positions.

its a good idea to set the engine at TDC before disassembly. note the location of timing marks on crank and cams to familiarize your self when you go to re-install.

Yes, you could of damaged a valve by rotating then engine or the cam. Now this only applies if it's a non clearance engine.. now what you might have done is rotated the cam out of timing while doing whatever it is you were trying to do. SO you might have to dis-assemble the timing chain/gears to try and reset everything

Timing the Cam to the Crank

There are several ways to time the cam to the crank. Be sure to check the manual before you install the timing chain or belt.

• Some timing sprockets are properly timed when the marks face each other.
• On others, there must be a certain number of chain links between the marks.
• Sometimes chains have colored links that must be aligned with the marks on the sprockets.
• Some overhead cams have a mark on the cam gear that lines up with a mark on the cylinder head when the timing mark on the damper is at the TDC mark.

Align the timing marks for the camshaft and crankshaft sprockets before removing the timing belt or chain.

If the old parts are available, carefully compare the new gears or sprockets with the old ones. Check the keyway and timing marks just in case there might have been an error made in manufacturing. Sprockets are sometimes stamped backward. Its much better to find the problem during assembly, rather than waiting until problems show up after reassembly and reinstallation.

Maintaining Valve Timing

During a valve job, it is essential to keep the timing chain or belt in place to maintain correct valve timing. Position the number one cylinder at TDC. Some overhead cam engines use a single long chain for a cam drive. The chain can be wedged against its guides with a tapered block of wood.
the chain tensioner on some ohc engines must be wedged to keep the chain in position during cylinder head removal. courtesy of nissan motors.

Some engines have a lower and upper chain. These engines do not require special attention to wedging the chain. Be sure to look for hidden head bolts and check the repair manual before removing the OHC head.

The 2 cams are linked with a chain at the rear of the cylinder head.

The cams need to be set so the slots on the chain sprockets line up with the cam tower caps with 16 links between cam caps.

You cannot see the front crank pulley tdc mark so you need to lock the engine at tdc with a screwdriver jammed into the timing hole on the bell housing after setting engine at tdc or use a DTI
to check to tdc in the #1 spark plug hole.

If the cams have not been disturbed you only need to set the belt cam sprocket to the mark and crank to tdc.....all this means pulling the core support into the service position so the belt tensioner can be locked down and/or doing a complete belt job along with a coolant pump if over 70,000 miles..

Your timing is off. You have to have the marks lined up.

when you got the chain on and the cam's timed and unloaded and locked the tensioner and installed the tensioner then the shoe guides did you unlock the tensioner before you turned it over
when you turn the engine over it will have a little bit of slack because it's only spring tension
double check the engine is timed correct don't worry about the colored links they only line up every 35 revolutions
if the crank and the cams are in time
you should be good
hope this helps
