Need firing sequence and diagrahm chevy s10 v6

Here is the firing order and spark plug wire routing diagram for a 2006 Chevy Impala LT 3.9 V6:
Firing order: 1-2-3-4-5-6
Spark plug wire routing (starting from the driver's side):

• Cylinder 1: connect to the coil tower closest to the driver's side headlight
• Cylinder 3: connect to the coil tower next to cylinder 1
• Cylinder 5: connect to the coil tower next to cylinder 3
• Cylinder 2: connect to the coil tower closest to the passenger side headlight
• Cylinder 4: connect to the coil tower next to cylinder 2
• Cylinder 6: connect to the coil tower next to cylinder 4

Note: Make sure to route the wires properly to avoid cross-firing.

Is the timing set to # 1 cylinder tdc or is 180 degrees out. Remove valve cover and bring cylinder 1 to tdc both valves will be closed, ensure distributor is set to number 1 firing.

An engine needs 3 things to run, fuel, spark, and compression. If you have verified that there is strong spark to the plugs and that there is good fuel pressure to the injector, you can see the injector fire on your truck by having someone crank the key while you watch the throttle body throat. If you have fuel and spark and have done a compression check then you need to check the timing. On your truck it should be easy to see by putting the crank shaft on the TDC mark and popping the cap off of the distributor. The rotor should be pointing to the No1 cylinder if you are on the compression stroke.

Crank at twelve and cam at six with number one cylinder tdc ?

You have to put the number 1 cylinder at Top Dead Center of the compression stroke, and then you install the distributor with the rotor pointing to the #1 spark plug wire tower that is on the distributor cap.

Pull the spark plug from number 1 cylinder. You need a helper to turn the engine over by hand (using a socket on the crank pulley), or he can bump the starter over in very short bursts. Put your finger over the spark plug hole. When the piston is rising on the compression stroke, you will feel air pressure on your finger. Now look at the crank pulley and turn the engine on over until the zero degrees mark lines up on the timing pointer. Or you can stick a long straw or similar into the spark plug hole (don't let it drop into the cylinder!) to feel when the piston is at top of travel...see, you feel for pressure build up with finger (piston is rising on compression stroke), when you feel it, turn engine on over by hand until the piston is at top of travel-that is TDC of compression stroke. Now install distributor so that rotor ends up pointing directly to number 1 spark plug wire tower. Then follow firing order -as the rotor turns, it will follow the firing order around the dist. cap.
There are two top dead centers of each piston, tdc of compression stroke and tdc of exhaust stroke- to time the engine, you need tdc of compression-that is when the spark plug fires in the cylinder, so that is when you want the distributor in with the rotor pointing to #1.

never power pressure wash it, or get water where its very hard to get out. (sealed bearing in alt, P/S/ and A/C are some)
dry out the ignition parts. this is called Misfire.
but once running right, drive far to get all parts fully hot. so its fully dry
next time do this in summer so it dries, faster and more complete.
you pulled the spark plugs all at once?
oops, that be bad, as most dizzy can be timed 4 ways.
and now you lost that secret
find true TDC firing, #1, zero degrees
then lay down the wires.
the V6 the most front cylinder is #1 (they are staggered)
V6 what displacement. ???
i think they are same. but./...
my 2.5L has COPS,
but yours a dizzy

1-6-5-4-3-2
F= front or water pump end, cam cog side.
F246 )bank 2
F135 (aka; bank 1)

none of this is usefull until TDC #1 firing is found.
the easy way is a compressioin guage to #1, max is fire.
turn engine by hand until this happens and the crank pulley
lands on TDC mark. , pull of Dizzy cap, see rotor. that true #1 spark wire. next time pull them 1 by one, or at least mark the #1 wire.
if you had nice NGK wire sets, mag wire,they are pre-marked.

I have the exact same engine. The firing order listed in my Chilton's manual is:
1-6-5-4-3-2

THE FIRING ORDER IS AS FOLLOWS : 1-6-5-4-3-2.
CYLINDER NUMBERS (front-to-rear) :
LEFT (driver side) 1-3-5
RIGHT (passenger side) 2-4-6

To set ignition timing, ensure that engine is at operating temperature, (190 degrees or above), bypass EST (electronic spark timing) by unplugging the single tan wire with a black stripe from the distributor. Ignition timing should be set at 0 degrees or TDC (top dead center). If not, loosen distributor hold down bolt and adjust, then retighten.

Remove cylinder # 1 spark plug, # 1 is the front one on drives side, turn crankshaft pulley to TDC on compression stroke, you'll feel the comperssion at cylinder #1 spark plug hole, follow cylinder # 1 spark plug wire to distributor cap, mark outer part of distributor where # 1 sits, remove distributor and restabe distributor with rotor at mark you made, then set timing.

Changing the spark plugs is a pretty easy task. The spark plugs run along both sides of the engine, 1 per cylinder. (3 on each side) You can easily identify them by the plug wires running to them from the distributor. Pop off each plug wire, (1 at a time) and replace the spark plug. Once you have replaced the plug, replace the plug wire. This ensures that you dont mess up the sequence of the wires which determines which cylinder fires at what time in the cycle. VERY important not to mess up the sequence. If you should happen to get the wires mixed up, look online for the firing sequence for your vehicle and engine.
