You are finding out why they recommend replacing the plug wires along with plugs. These 'wires' actually have no wire at all--just carbon-soaked-cotton-string covered by a heavy man-made rubber-like covering and metal adapters on each end. The clips on the ends are made to hook onto the respective parts so that they don't just fall off. They usually work well until physically disturbed.They do make a small tool that facilitates removal of the plug ends, but still recommend changing the wires. Hope this helps!

I drive a 95 toyota 4 runner.I would like to know the right way to check my sparkplug wires if working p roper.


You can fabricate a tester from a 6 inch long mongol pencil. Sharpen one end and drill a 1/8" hole in the middle. Now remove the sparkplug wire from each sparkplug and insert the pencil onto the sparkplug wire with the dsharpened end connected or touching the ground or any metal part of the engine. Start your engine and you should see sparks jumping on the drilled hole on the pencil which indicates that your spark plug wire is okay.

Fuel injector spraying too much fuel


Excessive cranking will put too much fuel into the engine. Have you tried holding the gas to floor and see if it starts. That will help clear out excess fuel from continued cranking.
Check for spark at a sparkplug wire. This will tell you if ignition system is working. You need to see a blue snapping spark to know ignition is good. If you are not sure how to check for spark, have someone help you. Easy to get a shock when checking for spark. You need the metal end of the plug wire just 1/8 inch to 1/4 inch away from a metal bracket or bolt on the engine. Hold it steady while someone cranks the engine over-watch for a strong blue spark to jump from metal end of wire to the engine. If no spark, your ignition system needs checked. If spark is good, have the fuel pressure checked-maybe it is getting too much gas.

Welli have towncontry i change computer but dont start and the inyector dont have electricity to star the car


Is the computer powered up? Does your check engine light come on when you turn the key to on?
If that's o.k., check fuel pump operation. Do you hear the pump come on to prime the fuel system when you first turn the key to on? It should turn on for about 2 seconds, and then stop again until the engine is being cranked, at which time the pump comes back on. You can't hear the pump when engine is cranking or running, but you could hear it first come on to prime the system. There may be a schrader valve-a test port- on top of engine on the fuel rail. If you find it, take the cap off, and press down the valve-gas should shoot up if the pump is working and getting fuel to the engine.
Now if the computer is powered and the pump is getting gas to the engine, and still no start, you need to check your ignition system by checking for spark at one of the sparkplugs. Pull a plug wire off a plug, pull the sparkplug out, reattach the plug wire to the plug, and lay the sparkplug on a metal part of the engine, so the sparkplug threads are touching metal (grounding it). Now have someone crank the engine over while you watch the plug for a strong blue spark there. You need to see a blue, snapping spark to know your ignition system is good. An orange spark is not good-too weak. If no spark, or not consistent, you have a problem in the ignition system, and will have to diagnose and fix that.
If all is good so far, you may need to check the fuel injection system. Start by pulling one injector connector off, and check for power on one of the two wires going to the injector (the other wire is the injector ground wire), with the key in the on position. If no power to the injector with key on, the injector drive circuit has failed. If one wire does have power, post back to me for how to test the injector ground circuit-very easy with a testlight.
Good luck.

How to change spark plugs


Those are as easy as they come these days. Mark each spark plug wire with a piece of tape with the cylinder # written on it, so as not to mix up the wires. Remove each spark plug wire by firmly grasping the wire by the boot (do not pull on the wire) and twist it back and forth a few times while pulling slowly. It should pop off without a great deal of effort. If it is seized and it breaks, you will have to replace the wire, or at the very least replace the terminals (if you can get some). Use an air hose and blow around the base of each spark plug to dislodge any loose dirt that could fall into the cylinders (not absolutely necessary, but a good idea). Remove each spark plug with a spark plug socket and extension and ratchet (I forget which size socket, it's either 5/8 or 13/16). Check the gaps of each new spark plug (typically around 0.035 in). re-install each new spark plug by hand (do not cross-thread them) and once you have ensured that the plug is threaded in properly, tighten the plug until it seats, and then tighten an additional 1/16 of a turn. Repeat this for the remaining plugs. Re-install wires to the corresponding spark plugs. You're done!

How do i change spark plugs in 1992 buick le sabre


To change the plugs, do one at a time so not to mix up the sparkplug wires, remove plug wire from a plug, use sparkplug socket to remove the sparkplug make sure to gap new plugs, ask parts store for the gap setting they will give it to you when plugs are bought, the plug gapper is about $2.00. and that about it, the rear plugs are a little harder to get to but the same way to remove, some buicks came with metal heat sheild over the sparkplug boot in the rear cylinders make sure to reuse, you will know if you have them they will slide right off old boot.

1998 dodge 1500 5.9 will not start, Just installed plugs, cap and wires 2 days ago and it was running great. I ran an errand this morning ran great. But now I can't get it started. I know it has and is...


you can check for spark by plugging in one of your old sparkplugs to one of the spark plug cables and letting the sparkplug lay on the bare metal of the engine. Turn over engine to see if the spark plug is producing a spark. No spark? Check under the distributor cap, take a look at the rotor for damage.

CHANGING SPARK PLUGS 2002 TACOMA 4 CYLINDER


Starting on the pasenger side. Remove the intake tube running from the air filter box to the throttle body and disconnect enough tubes to swing it out of the way. The sparkplugs are down below the small coils you see at the end of the sparkplug wires. With a 10mm socket remove bolt holding the coil, disconnect the plug at the top of the coil by squeezing it at the top and pulling straight off the coils.

Pull the coil straight up. there will be about a 6 inch tube that connects to the top of the spark plug when inserted. You will need a 5/8 sparkplug socket and about 2 feet of extensions to make it easy on yourself. Insert the spark plug socket and extensions down the hole you removed the coils with the tube from and remove and replace the sparkplug. Reinstall your coil onto the engine and move to the next one until you have replaced all the plugs on the passenger side.

Make sure you reconnect all the plugs to the coils, hoses to the intake tube and reinstall your intake tube. The drivers side is a little easier. Pop the spark plug wires from their plastic holders to free enough slack to be able to pull your sparkplug wires out of the block. For the plug closest to the front of the engine you will need to remove the 10mm bolt holding the ground wires to the intake manifold to be able to free enough space for removing the plug.

For the middle plug you will need to remove the 10mm bolt holding the bracket that is holding one of the throttle cables at the top of the intake manifold. For the rear plug just pop the flexible hose that runs behind the black metal bracket straight up out of its clip and push it out of the way along with any other hoses that run through this area. Pull the spark plug wire from its place by pulling straight up just like with the coils. there will also be about a 6 inch tube running down to the spark plug at the bottom of these plugs.

Remove and replace the plugs same as before. make sure you reconnect all your hoses and wires to their previous locations. Doublecheck to make sure you reconnect all the ground wires/ brackets. Also you will need to use " twin ground electrode plugs" (see sticker on front of your plastic timing belt cover? to the right of the radiator hose).

How do I check an ignition coil on a 1993 Corolla 1.8L


Take the wire off the spark plug then remove the spark plug, put the wire back on the plug and lay it down on something metal .Have someone start the car and look at the sparkplug gap to see if it is sparking. Use a new sparkplug to be sure its a good plug and do this when its kind of dark out side so its easy to see the spark.If it does not have a spark,the coil is worn.
I hope this helps you.

The best way to check for spark is to remove a sparkplug wire from one of the sparkplugs on you engine and then take one of the spark plugs that you replaced and connect it to that plug wire. Make sure the plug is touching bare metal and have someone crank your engine. You should see a spark at the end of the plug. As far as a stuck injector you need to see if your getting spark first. Let me know what you find.
