3.1 tming chain

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.

If you have ANY doubts about doing this PAY someone to do it!! You will need to reset all of your mechanical timing. This is one of those jobs where if you get it wrong it will be a VERY expensive repair! This is an 'interference' engine meaning pistons will hit valves if the timing is wrong.
I would seriously recommend you buy a good workshop manual and read it through at least three or four times BEFORE you try this.
First find ALL of the timing marks on the Cams, Crank and the Chain. You will need to move each Cam and the Crank to line up the timing marks EXACTLY. You might need to turn the Crank to NO MORE than an eighth of a turn past Top Dead Centre, (clockwise). This gives clearance to turn the Cams. Line up your Cam timing marks.
Turn the Crank Back, (counter clockwise), NO MORE than the original eighth of a turn back to Top Dead Centre. Re-check ALL of your timing marks!
Mount the timing chain and set the chain tensioner. RE-CHECK all of your timing marks again. By hand turn the crank CLOCKWISE 2 full rotations. The timing marks should line up again.

Something wore out or broke

Timing belt or chain?
If you have chain align the dark mark of the chain to gear marks and release the tentioner . after you turn one time the mark wont match to the chain for long time.
if you have belt. the marks are on the dots on the head and block and will match every second turn on crankshaft
after you install belt/chain turn with hand ,don't start till you're sure the piston don't touch the valve .
with chain you can mark a dot on the block and head with marker to see if will come back to the same spot on same time crank and cam but is not accurate .
good luck

okay first you make sure the timing marks on the pullys or gears are lineing up also you find #1 cylinder pull out spark plug place a long phillips head scew driver into the hole turn the main crank it should rise and fall get the lower part of the engine to where the scew driver stops rising and right before it falls you should be at top dead center on the lower part of the engine. turn the cam shaft till the timing mark on the pully or gear is at top dead center (TDC). but you should have timing marks on the crank shaft pully and the cam shaft gear or pully I recomend a chiltons or haynes manual so you can locate these marks.

your most likely 180 out on crank shaft vaves are hitting piston

timing chain ? it is 8 vavles ,if both yeah
http://www.bimmerwerkz.com/forum/3-series-e36/m40-motor-timing-info-59059.html that is crankshaft marking and the camshaft marking ,u could see the line up (arrow)marking at the top ,after that turn the crank by hand few time then lines up ,if match then is all good

if you mean the timing chain then on your crank gear and your cam gear there will be a mark on each sometimes they look like a dot the dots need to look like this for perfect timing ( . . ) this will be there closest position. Your crank turns once all the way around (360 degree) and your cam gear will do two complete revolutions to the one of the crank gear. so when you set your marks as above when you turn the crank one half turn the mark on the crank gear will be at the bottom and at the same time your cam gear will have made one complete revolution, so when you turn the crank another half turn your cam would have turned again a complete revolution and the two marks should be at their closet point again.

Rotate the cam on position and move the crank where it needs to be and rotate the cam back where it should be. This way you're getting the valve out of the way so you can get the piston where it needs to be.
