Timing and Firing Orders
Firing order refers to the order of power delivery of the cylinders in an engine. Timing and firing orders both contribute to the engine’s fuel economy, power, and longevity. Achieving the proper timing is critical in the engine’s performance.

How do you replace spark plug wires on 1999 Camry?
Very simple to do. Purchase 4 new platinum spark plugs for the vehicle. You will need a spark plug socket (it has rubber on it to grip the spark plug you are taking out) and an extension of at least 8 inches. When you open the hood you will see the 4 spark plug leads on top of the engine. Unplug the leads ....put the spark plug socket down each hole and unscrew the spark plugs. The new spark plugs will likely be already gapped to the .043 inches needed. Screw the sparks plug in (I made sure I did not put the spark plug socket on the spark plug too tightly or you could leave the spark plug in the socket hole. A 15 minute job at the most
How do you set the timing on a 2000 Kia Sportage?
You don't! The computer, crank and cam sensors control timing.
How do I change the spark plug wires on a 1997 GMC sierra?
Just buy a set of custom plug wires designed to fit perfectly. Lay the new wires out and sort by length. Now remove just one old plug wire. Caution: "Remove, and replace them, one at a time, so you will not get them confused or mixed up." Place a very small amount of dielectric grease inside the boot of the plug wire and insert it over the spark plug until it snaps in place. Do the same at the distributor or coil pack if so equipped. Make sure to route the new wires exactly the same as the old ones. Take your time and use care handling the wires. Good Luck.
What is the firing order for a 1996 ford f250 351?
The cylinder order is 1, front left bank- nearest the radiator, 2 3 4 (all on the left bank, counting towards the firewall), 5- nearest the radator on the right bank, 6 7 8, ending at the firewall on the right bank. The firing order is 1 3 7 2 6 5 4 8. Hope that helps!
It's possible, but if you turned the engine off/put the tranny in neutral immediatly, you should be ok. Replace the belt and turn the engine over a couple of times (avoid starting, if possible) with a friend standing over/near the engine. If they don't hear and wierd noises (odd ticks or clicks), start her up. Listen carefully, if you don't hear anything out of the ordinary - you should be good to go.
What is the firing order for a 1994 Mitsubishi mirage 1.5L?
1-3-4-2 Distributor rotates counter clockwise. Number 1 plug is on far left driver's side.
How do you find or identify or relate the firing order to the firing order on the distributor cap?
You can't always go by the absolute distributor cap position. Sometimes the gear has been turned over the life of the engine, so if you have removed all sparkplug wires and have to start over there are a few simple things to try: Turn the engine by hand until you see the #1TDC mark comming up. Cover the sparkplug hole with your finger and then continue to turn the toward TDC. If you feel no compression as you turn the engine, the crankcase is 360 off and the distributor is 180 off. If there IS compression, you're comming up on TDC. When the timing mark comes to top and you're building compression, the distributor rotor is pointing at #1.

First of all, that engine was designed by aliens. No one from this planet could have ever dreamed this thing up. You not only need a special tool, you need a whole set of special tools. We have a large case full of pieces to special holders and alignment tools for the cam shafts and the crank shaft on that engine. Everything has to be aligned with those tools, and held into place with the special holders, while the chains are being installed. There are probably 15-20 pieces to that set of special tools. Not only are there no timing marks, there are no woodruff keys on the gears either, so if you take the bolts loose, the gears freewheel on the camshafts. So you have to have the special tools to align and hold the camshafts themselves, while you tighten the gears down onto the camshafts. You will not get that engine timed without the tools. Also, that engine is an interferrence engine. In other words, it bends valves if you crank it over out of time. You also are supposed to remove all of the cam rockers before working on that engine, because simply turning the crankshaft or a camshaft while installing the chains can bend valves.
FOUND A WAY Alignment of the ford 4.0 SOHC engine is easier than it looks. The basics are the main jack and crank shaft gears have timing marks that point toward each other in alignment with the center of the crank and jack shafts. The key way on the crank and the wide notch on the damper pulley are in line with the center line if you can not find the TDC mark on the damper. Set the crank at TDC with the timing mark (mine has marks I just needed to clean the rust off) or line up the wide notch or key way with the center of the jack shaft which you can see threw the front RT timing chain area. Make sure your came are set with the narrow side of the slot opposite the drive gear toward the head and almost in line with the head. There is a point where the valves do not hit the pistons and you will need to be there for the next step. If the valves hit the pistons while turning the cam you will need to move the crank until they clear then set the TDC. The cams are a little trickier. On the end of the cam opposite the gear is a slot. It is 6mm wide. When you look at it the slot is off center so one side is on the center line of the cam shaft. Position the cam shaft so the short side is facing the engine. Alignment is made by placing a clamp that cost too much money on the head with a bar that holds the slot parallel to the head. Conveniently the center line of the shaft is 42mm (1 5/8") form the head. I took a bar 1 ½ X 1/8" to span the head and laid a 1/8" thick bar on top to enter the slot. The cam shaft on the gear end has an area with flat sides that a wrench can be used to hold the cam while setting it. While holding the bars and cam in place check TDC and tighten the timing gear. If you want to buy the tools they are at www.denlorstool.com. Search (OTC 6488 kit) part # rotunda 303-577 (T97T-6256-c) a roller cam removing tool makes life easier in that you do not need to worry about bending valves. While on valves a quick check for a bent valve…. Position the cam with closed valves and piston down all the way. Use your compression tester extension hose to adapt the spark plug hole to an air line. You will need an air tank with a about 5 gal. on a good compressor. Apply the air and check for leakage from exhaust and intake. You will have some because the valves seat for 300bls and you are only putting in 100 or less but a bent valve will blow by worse than the others.
good luck and don't bend your valves

What is the correct ignition timing for a ford 460 cid motor Thanks?
It depends on the year, which engine code it is, what emission equipment is installed etc. Check the underhood specifications sticker - hopefully it is still there and readable. It should be in front of the radiator somewhere.
What is the best way to remove the spark plug wire caps on the dtribution harness?
It's honestly a better idea to just give in and go buy a new set of spark plug wires... You will tear them up and cause a dead short if you try and pull the caps off of the wires... most of them are glued on, and they can't take much pressure if you pull on them... sorry. Just buy new ones, you'll waste less time that way, and they are not really that expensive.

1990 Nissan maxima 3.0 firing order?
if its a sohc the firing order is 1-3-5 then 2-4-6 odd cylinder is the back near the fire wall and as far as the distrubitor it should be numbered.
What is the firing order of a 4 rotor rotary engine?
1-3-2-4 Rotors 1&2(which are 180deg apart) are phased 90 deg from rotors 3&4 (which are 180 deg apart). Imagine a pair of 2 rotor eccentric shafts front to back, but the rear shaft is 90 deg offset to the front shaft.
