firing order

[Bambino]

correct me if I'm wrong, the firing order is 1 3 4 2 right,? 1 is to the nearest of the radiator right? cuz that's what I'm going by in the book and its not starting,

[Guest 510kamikazifreak]

right..

counterclockwise?

[Guest 510kamikazifreak]

has the oil pump been dropped out?

[Dat Lurka]

I wonder if I've been driving around with wrong plug order this whole time...

[datzenmike]

L20B rotors point in different directions than other L series and dizzys could have been swapped. The oil pump spindle could have been moved to another position so the rotor could be pointing anywhere.

 

Set at TDC compression on #1 cylinder.

 

Now take the distributor cap off and see where the rotor is pointing... THIS now becomes #1 plug . Go counter clockwise 3 4 2. Done.

The most common is 2 and 3 swapped.

The one "good" thing about a L-dizzy/pump is one can put the rotor where one wants :rofl:

okay I'll check that out

Set at TDC compression on #1 cylinder

Note that when you set the engine to the TDC (0) mark, it could be #1 or #4. The timing mark will not tell you.

 

And btw, all inline 4 cylinder engines are 1-3-4-2, american, japanese or european. At least I've yet to come across an L4 that wasn't 1-3-4-2.

3 2

4 1

[Bambino]

thank mike it worked.. yeah mine is

1 2

3 4 going counterclock wise

[Bambino]

thanks again guys

This is why I said compression. Just stick your finger in the #1 plug hole and bump the starter until it pops out. Find the pulley mark and turn up to the timing pointer.

makes your firing order 1432 (or 4321, 3214 or 2143, but lets start with 1)

 

the firing order for all L4's as stated is 1342. based off your firing order I'd say you're runnin on 2 cylinders. pull 3 and 4 plug wires off. see if there's any change. if no change in how it runs swap them to 1342 and I bet you'll have a lot more power

How is this possible? The next plug to fire after #1 is #3. You have #2 next??????????????

 

I say you're trollin'

[Dat Lurka]

I didn't say it was right.

[FiveSeventyZee]

oh damn I was going clockwise! lol your firing order would be 1234 then. Which when compared to 1342 would actually predict only one cylinder firing...lol

[Dat Lurka]

I was mistaken. It's

31

42

[HRH]

Actually, not all firing orders for inline four cylinders are 1342. Mazda Miata is 1432 as it uses coil packs. :D

[ggzilla]

Hmmm...the miata I worked on was 1-3-4-2. Are you thinking of.the coil order? That's differ than firing order.

[HRH]

True, coil order vs. firing order. For figuring out the arrangement though, 1342 will not work for the coil packs. Not that you'd confuse those with a distributor, but I could see some not familiar with coil pack ignition doing just that. And then there are the people who put WD40 on belts to stop squeaking. :D

Dat Lurker???????????????

what?

 

its 1 3 4 2 counter clock wise fire order nothing else !!!!!!!!!!!unless you have a special cam that will need a different fire order.

 

motor is at TDC with 11/28 spindal position

[Dat Lurka]

It is 1342, read my last post lol.
