Some times it is easier to pull the tire off and remove the inner fender well to access the plugs. You can get it out without doing that, it's just a major pain. Also you might try using a swivel on the socket.

No, just be careful when you are disconnecting the wire from the plug, if you pull too hard you may rip the inside of the wire out, than you will have to replace the spark plug wire as well.

A 3/8 and sparkplug socket should do the trick.

#8 coil pac, cylinder misfire...Need diagram The mechanic says I need a coil pack and spark plug replacement for the #8 ...Need diagram to figure out which one it is. it is


The #8 coil and spark plug are located on the drivers side rear of the engine. You will need a 7mm socket to remove the bolt that holds the coil down. After the bolt is out, pull the coil upwards and remove. Next you will need a 9/16" spark plug socket to remove the spark plug which is located in the hole that the coil came out of. The spark plugs in a 5.4L engine are sometimes frozen into the engine. If it is very hard to turn the plug, try spraying some WD-40 down the hole onto the plug and let it soak in for a while. Do not try to force the plug to turn, it will break and a special plug extractor will be needed to remove it.
Hope this helps you!

I replaced my spark plug wires on my 1996 chevy truck. may have crossed one,need a diagram from the spark plugs to the distributer cap.


Since you didn't state whether it is a V6 or V8, I'll give you both.

V6 -4.3Liter
Firing Order is 1-6-5-4-3-2
Distributor rotor turns Clockwise
Number 1 spark plug tower on distributor cap, faces the front of the engine.

->Drivers side, spark plug order in engine, starting from the Front going back:
1-3-5
->Passenger side, spark plug order in engine,
starting from the Front going back:
2-4-6

If it's Electronic, the distributor cap has a Left side, (Drivers side), and a Right side, (Passenger side)
Starting from the Front, going back on the Left side,
3-1-5
Starting from the Front going back on the Right side,
2-4-6

V8-5.0, 5.7, and 7.4Liter
Firing Order is 1-8-4-3-6-5-7-2
Distributor rotor turns Clockwise
Number 1 spark plug tower on distributor cap,
faces Front, towards the Drivers side.

Electronic distributor cap has two sides. Drivers, (Left), side and Passenger, (Right), side.
Starting from Front going back on Drivers side,
1-7-3-5
Starting from Front going back on Passenger side,
8-2-4-6

Spark plug order in engine, starting from Front going back, Drivers side:
1-3-5-7
Spark plug order in engine, starting from Front going back, Passenger side:
2-4-6-8
