How do I find and replace spark plugs, check wires on an I30 2001

To check the spark plug wires on your 1992 Pontiac Grand Prix 3.3L V6, you can follow these steps:

1. Locate the spark plug wires on the engine. They are usually connected to the spark plugs on the top of the engine and the ignition coil on the side of the engine.
2. Inspect the wires for any visible damage, such as cracks or cuts. Also, check the connections at the spark plugs and the ignition coil for any signs of corrosion or looseness.
3. Use a spark plug wire tester to check the wires for proper resistance. You can purchase a tester at an auto parts store. Follow the instructions provided with the tester to check each wire.
4. If a wire fails the resistance test, replace it with a new wire. Be sure to replace each wire one at a time to avoid mixing up the order.
5. After replacing the wires, try starting the engine again to see if the problem has been resolved.

If the problem persists after checking and replacing the spark plug wires, there may be other issues causing the engine to not start, such as a faulty ignition coil or fuel system components. In that case, it may be necessary to take the vehicle to a mechanic for further diagnosis and repair.

If theres no spark from the spark plugs then you would have to replace them?

I'm sorry to hear that you're having trouble with your 1989 Mitsubishi Eclipse. Here are a few things that you can check to try to get spark to the spark plugs: Check the spark plug wires: The spark plug wires can become damaged over time, which can prevent spark from reaching the spark plugs. Inspect the spark plug wires for any cracks or breaks. If you find any damage, replace the spark plug wires. Check the spark plugs: The spark plugs can also become fouled or damaged over time, which can prevent spark from reaching the spark plugs. Remove the spark plugs and inspect them for any damage. If you find any damage, replace the spark plugs. Check the ignition coil: The ignition coil is responsible for generating the spark that ignites the fuel in the engine. If the ignition coil is faulty, it can prevent spark from reaching the spark plugs. Inspect the ignition coil for any damage or signs of wear. If you find any damage, replace the ignition coil. Check the distributor cap and rotor: The distributor cap and rotor are responsible for distributing the spark from the ignition coil to the spark plugs. If the distributor cap or rotor is faulty, it can prevent spark from reaching the spark plugs. Inspect the distributor cap and rotor for any damage or signs of wear. If you find any damage, replace the distributor cap and rotor. If you have checked all of these things and you are still not getting spark to the spark plugs, it is possible that there is a problem with the engine's computer. In this case, it is best to take the vehicle to a qualified mechanic for diagnosis and repair. Here are some tips to help prevent these problems from happening in the future: Change your spark plugs and spark plug wires according to the manufacturer's recommendations. Keep your engine clean and well-maintained. Avoid running your vehicle on low fuel. If you notice any problems with your vehicle's performance, have it checked out by a qualified mechanic as soon as possible.

Code po305 is # 5 cylinder misfire. Check the spark plug wire and spark plug. use an inline spark tester to check the wire from coil to spark plug. If you have spark,then remove plug to see if it is fouled out. the best time to check for brake or cracked spark plug wiring is at night with engine running and doing a walk around to see if the insulation on wireing is broken or cracked. you will see the wires sparking at night. then replace the wires that are causing the problem.

While checking for "spark" = "fire" make sure you do it properly. These shocks hurt and could result in injury or even death.
1. Pull and check the Spark Plug for Cylinder #3. There are spark plug tester's at autoparts stores that you can buy and some are for rent. They are easy to use. If still no Spark PROCEED to Steps #2 and #3 below before replacing the Spark Plug. If the Spark Plus is dirty, fouled, or incorrectly gapped: clean, and regap the plug and recheck.
2. Check for "fire" at the spark plug end of the wire for Cylinder #3. Is there consistent sparking? If not then PROCEED to Step #3 below before replace the wires.
3. Check for "fire" at the Coil="Distributor" for Cylinder #3. Is there consistent sparking from the Coil? If not the Coil could be Bad.
If there is Consistent Spark from the Coil but no Spark from the Wire = Replace the Wire.
If there is Consistent Spark from the Coil and Wire = Replace the Plug.

You need to check alot of things to isolate the problem. Start with the air cleaner. Make sure it is not filled with dirt. I would check the spark plug wires. Crank the car. Take a spray bottle filled with water. Spray some water on the spark plug wires and the ignition core wire. It should make NO sparks. Turn the car off. If it made sparks or arcs, replace spark plugs wires and coil wire. Also, make sure that it takes effort to remove the spark plug wires. I have seen spark plugs wires that come off real easy. These should be replaced. You will need to remove one spark plug wire. Only ONE. (you don't want to crisscross the wires.) Remove the spark plug. Check the condition of it. Check the gap. If bad, replace. (I put anti sieze compound on the spark plug threads. Just a little bit.) Remember to fix one spark plug at a time. (You don't want to get the spark plug wires crisscrossed.) Move to the next spark plug. If the spark plugs look alright, I would check the distributor cap and rotor button. (It requires a little patience.) If all this looks good, I would do a compression test (if you have a compression test gauge). If not, check the fuel filter. Fuel should flow thru the filter. If this is good. I would put a vacuum pump on the fuel regulator. (If my a vacuum pump is not handy, I use a piece of tube and **** on it. However, safety conscious people would not think of doing this.) There are other things to do, but it starts requiring specialized tools.

check plugs wires for damage or just replace if you have replaced the #3 plug already if not replace it also
