You do not state the engine type but…
Here is the standard firing order for the V6
[/quote]
Hmm. Another diagram showed number 1 being in your number 6 spot on your diagram…
It’s a 1999 Pathfinder SE 3.3 v6.
[color=#00bbff]Simple enough to confirm:
Remove the spark plug from the indicated #1 cylinder.
Bring it up to the top of its compression stroke ( place a finger over the spark plug hole to feel compression )
Use a long thin screw driver or piece of wire and put it in the spark plug hole until you touch the top of the piston.
Hand crank the engine slowly until the wire or screw driver rises to its highest point.
Now look at your harmonic balancer, it should be at 0 degrees.
That will tell you your at TDC on number 1 cylinder.
You can also remove the distributor cap and the rotor will be pointed towards that cylinders spark plug wire on the cap.[/color]
Now when I use the gun without a display, I’m just getting the number by visually looking at it, so it’s just an approximate, correct?
I have no idea what your talking about, never used a timing light with a display.
And is it suppose to be pretty jumpy. Like kind of shaking around from 10 -13 for example or is suppose to be still?
[color=#00bbff]There is a procedure, at least on my 2002, 3.3L Xterra : it is as follows
You run the engine @ 2000 rpm for 2 minutes under no load.
Rev it to 2000 – 3000 rpm 2 or 3 times under no load, then let it return to idle.
Turn off the engine and disconnect the throttle position sensor connector from the throttle body.
Restart the engine and rev it to 2000 – 3000 rpm 2 – 3 times under no load then let it idle
Then check engine timing 10 degrees +/- 2 degrees BTDC in Park
If the idle is fairly stable ( some where around 700 rpm) and the rest of the engine is mechanically sound, the timing mark should be fairly stable.[/color]
[b][color=#00bbff]dtidman gave you the link to the FSM for your vehicle
A 3rd party manual is a joke compared to the FSM
Try reading this:
Pages EC37 and EC38 for your engine, also on page EC11 shows the firing order for your vehicle.
Might suggest you download the entire FSM ( I did for my vehicle ) it’s free and worth every word of information.[/color][/b]
