firing order needed?

It can be a 292 6 cyl, 350 V8 or 454 V8.. (unless someone swapped in something else...)

292 - 1-5-3-6-2-4
350 and 454 - 1-8-4-3-6-5-7-2

Number one is the front drivers side cylinder.

i just replaced my plugs and wires,along with the distributor cap and rotor,,i think i screwed up and got a few wires mixed up,,must be close cause its running,,but running rough.anywhere i can get a diagram that shows what wire to what plug,,have the hanes manual but it just tells me the firing order and does not work as i understand it,,its a 4.3 litre

See below

i have this truck and we have done the 18436572 firing order but we cannot get it to fire yet we are at tdc and it seems like the rotor is in between the 1 and 8 on the distibutor cap we have reset the timing several times already and it still won't fire if you can give me any info i sure would appreciate it.

firing order is right. did it run before the timing got messed up? what happened? the more dtails the better the diagnostics

The intake manifold, should have the firing order stamped on it but I've will send you this photo.

i need to know where the number 1 pin on the distributor cap is so i can put the firing order right........i believe the order is 18346572 not really sure about that either

I found the above picture. If you put the number one cylinder on tdc of the compression stroke whichever plug tower the rotor is leading into, should be the number one plug tower.

i was wondering if i could get the firing order for the 4.3? i am a bit leery about these sites you must understand.

1-8-4-3-6-5-7-2 Dont forget the roter spins clockwise. Hope this helps...........larry

I had to remove the distributor to do some work on my truck and put the spark plugs back in the wrong order the eng is now back firing can you help me with the firing order so that I can reset the spark plugs wires correctly.

The firing order is 18436572. Here is a diagrams to help show you.

i pulled the distribuator,checked gears,then went to put it back.changed coil,put new moduale,had roto poited at no 1 and did plugs to fireing order. still wont start and pufs smoke out of carb.what did i miss.

That means either the timing or the firing order is wrong.

fireing order is what was on the motor.dose rotor have to point to no1.

Did you have #1 cylinder on tdc of compression stroke before you pulled the distributor? Put the #1 cylinder on tdc, look to see where the rotor is pointing. If you can blow air into number 1 cylinder, its not on tdc or something else is wrong? You can use a fuel line hose that will fit snuggly in the spark plug hole, try to blow air into cylinder. There are other ways to check that.

hello guys, didnt mean to butt in, Im a slow typer.

set timing line with marks on balacer.thought that was tdc

Blow into the cylinder????? never heard of that one but it sounds like a great idea

LOL

ok blow air with compressor or mouth..never heard that one but will try.just put a hose into the hole and if u can blow air its not tdc..right

I changed my plugs, but I may have gotten them out of order. I tried to pull one and replace one, but I had taken off two, before I decided to go one by one. I just want to make sure they are in the right order.

the firing order is 1-8-4-3-6-5-7-2 the number one position is 11:30 on the distributor cap. That's looking from the driver's seat. The distributor turns clockwise. That should get you going.

How about telling us what engine you have here?

ok its a 305.when i pulled the distribuator out i did not have it on tdc.then i found tdc put dist.back in with rotor pointing at no1.still nothing.then changed coil,,nothing then replaced module,nothing.all it dose is turn over and puffs out of the carb.could it b out by 180??

Sure it could be if you didn't make sure it was TDC on the compression stroke. Most people just hold their finger over the spark plug hole while rotating the engine and you will feel the compression when you're approaching #1 TDC.

i just put the line on the balacer in the middle of the marks then check with a srudriver but feels like there is still a small gap on top of piston.is this wrong

You still need to know that you are on the compression stroke or you will be 180 out. The crank rotate 2 times to every one revolution of the distributor.

ok i see.i,ll try that finger over the hole trick.thanks for the info.
