IF IT'S A V6 EASIEST WAY IS THRU THE WHEEL WELLS
Disconnect the battery, remove the spark plug wires and covers, and remove the old spark plugs. Next, put in the new spark plugs, attach the covers and spark plug wires and reconnect the battery.
replacing coil does not work for long
Yes.
First you remove the spark plug wires from each of the spark plugs, being careful not to wreck the wires. then you get a deep well socket that fits around the spark plugs. then you take out each of the spark plugs. get the new spark plugs and insert them in the spark plug holes. tighten them up and put the spark plug wires back on the plugs. I find there is more room to work if you jack up the front of the truck and remove the wheels. With a long extension you can easily reach five of them thru the wheel well. The one behind the steering shaft on the drivers side is a challenge.
good rule of thumb on spark plugs. .035. If it's too small, it will still fire. If it too wide, it won't.
Probably in need of a tune up, spark plugs, ignition wires, distributor cap and rotor.
check spark plugs
Is it a brand new distributor ? If not then replace the module and pick-up coil in the distributor that you have.
It is screwed into the drivers side head between the first 2 spark plugs up front.
Bust your knuckles with the use of a mirror to see the plugs and a magnet to pick them up when they drop under the engine block!
I like to jack up the front and remove the front tires. Using a 3/8" drive ratchet and a long wobble extension with a spark plug socket you can reach thru the wheel well openings with ease.
No spark.
