FIRST!! if you have an electric fan disconnect it cause they can kick on at any time and it'll be a nasty mess you'll have to clean up!!

make sure your car is at normal operating temp and your idle is correct,

make sure you car is in park (automatic) or neutral (stick) and the e-brake is ON!!!

the timing marks on this model are on the flywheel and you can see them through a timing check hole located in your bellhousing.

pull you vacuum advance hose off of your dist. (you dont have to plug it)

and attach your timing light to where ever you need to attach it to!

with your car off loosen the dist. just enough to where you can move it with your have but not loose enough to where it will move freely!!

on early models on the side of your distributor body there will be a set of #'s stamped there!

early 84' models have 0 237 002 080

late 84' and 85' models have 0 237 002 096

the early 84 has a symbol that looks like a upside down OT with that line through the middle!!

the later models have what looks like a Zo symbol but it'll kind of look like Z degrees!

if the marks are aligned correctly through the hole than it's fin but if they're not then you'll have to turn your dist. a little either way!!

when everything looks good tighten everything back up but make sure you double check everything you've done just to make sure it's gonna stay that way!!

I have a 2003 mazda 6 with 2.3 i think it might be out of time but i cant find the timing marks on the pulleys

Sir. The only other way to know your on no one cylinder top dead center is to take the numbers of the firing order,
White them down with the first 3 in one colum and the second three firing numbers in a colum next to the first three. The numbers across from each other are called " mating cylinders".
If #1 cylinder is ( example ) next to #6 on your paper, then those two are mating cylinders. Meaning one ( with valve cover/s off) will , when engine in turned over slowly, will be on valve overlap, while its mating cylinder is on
Top Dead Center to fire. In valve overlap, when the motor is turned slowly one way, the exhaust valve will open and when engine is slowly turned the other way, the intake valve starts to open. At that point when either exhaust or intake valve is moving on #6 cylinder valve trane, #1 is at top dead center which will be not even 180degrees out, but top dead center on #1 cylinder. Now your at the firing point of #1, which will coincide with the rotor pointing at #1 plug wire on the distributor cap. In essence, static ( not
engine running ) the rotor bug should be about 17 degrees early in the cap. This makes up for slack in any timing chain and gear slack between the distributor gear to cam gear. This when running put you about 4-6 degrees advanced. Computor models will time it for itself. See example below.
1 - 6
5 - 2
3 - 4
If your timing order is 153624 then use the chart. As you list your order on paper, remember one mating number is firing and it's mating cylinder is on valve overlap. 180 deg out would be
#1 valves " rocking " and no 6 is on compression. When a cylinder is on the compression stroke, valves will not move. ( both closed ). So, write down your timing order, v6 or inline 6, or 4 cyl or 8 cylinder. It don't matter. If you look at the manifold , it will give the timing order, maybe on the head or Internet. Two columns, walla.
Hope that helps get you to true #1 top dead center. This system is the only true way, along with a cardboard timing wheel for the crank if needed , to adjust valves, lifters and know where the engine is at all times.
Hope that helps. Sorry for the detail, engines are really very simple, once you " get the picture ". Don't make it to difficult. Crank turns two times to one revolution of the cam.

97 chevy c1500 timing chain install 350 it will not run put gas intake it back fires.

Two possible errors . Check that the timing marks are correct and check the firing order of the plugs as the leads may be swapped around or the distributor has be installed incorrectly causing the firing order to be out. Do a compression test to check for bent valves.

How do i know were is number one in my dist no numbers?

You can remove the number one cylinder spark plug, put a socket and wrench on the crankshaft pulley bolt, and with your finger or thumb over the sparkplug hole, turn the crank around clockwise until you feel pressure build behind your thumb over the hole-it will be slight, but you can feel it. The number one piston is approaching its firing position- the power stroke (there's no pressure build-up on the exhaust stroke cause the exhaust valve is open). Now stick a long straw or pencil into the sparkplug hole (Don't drop it in there!) Just feel for the top of the piston as you slowly turn the crankshaft on around. When the piston is at the top of its stroke (top dead center of its power stroke), the rotor on the distributor will be pointing to the number one spark plug tower. Then follow the firing order as the rotor turns. Oh, and if the crank is too difficult to turn by hand, it helps to remove all the spark plugs. Just be sure which cylinder is number one on your engine.

Timing chain broke replaced it now car runs rough. rechecked timing

Put a vacuum gauge on the intake manifold. (any port)...If the needle is bouncing, likely you have a bent valve. Some engines are "interference" but even those that aren't can still have a valve/piston collision if the chain (usually the top gear) fails. Also check firing order etc.

replacing the timing belt does not change the firing order. the dist should only go in one way. the firing order is, 1 3 4 2
