SOURCE: Engine starting trouble


It sounds to me like your starter is not engaging until you have tried it several times. This may be a sign that there is damage to the starter or the flywheel. When you crank have someone listen near the front of the vehicle. If you hears a grinding or jingling sound it may be that they are missing teeth on the flywheel or the sprocket inside your starter.

If you check this and that is not it please message back here and we'll try to help you further

SOURCE: installing spark plugs on the firewall side

I don't tilt the engine, If you reach under on the left side (rear) you can reach all plugs to remove and replace. Once you get your hand under the ignition module there is alot of room.

How to change Spark Plugs in a 2007 Toyota Rav-4 with a 3.5 V-6 engine

1. Check the gap at the base of the new spark plugs with a spark plug gap tool. If the gap on any plug is not between 0.039 and 0.043, exchange the plug for a new one. Do not attempt to adjust the gap on the plugs.
2. Open the two latches on the passenger's side of the air-filter box. Pull the front half of the air box toward the front of the engine and push it to the side. Remove the air filter from inside the air-filter box. This allows you access to the ignition coil packs.
3. Unplug the wiring harness from the top of one coil pack. Remove the bolt securing the coil pack with a ratchet and socket, and pull the coil up from the engine.
4. Remove the spark plug using a ratchet, 6-inch extension and a spark plug socket.
5. Hand-tighten the new spark plug into the RAV4's engine and torque it to 14 foot-pounds with a torque wrench, 6-inch extension and a spark plug socket.
6. Squeeze a small amount of dielectric grease into the rubber boot at the bottom of the ignition coil pack. Push the coil pack onto the new spark plug until it clicks into place. Tighten the coil pack bolt to 6 to 7 foot-pounds with a torque wrench, 6-inch extension and a spark plug socket. Reconnect the wiring harness on the top of the coil pack.
7. Replace all four spark plugs, by repeating Steps 4 through 7 on all four plugs.
8. Sit the air filter back into the air-filter box. Reinstall the front half of the air-filter box and close the latches to lock it in place.

good luck

How do i change the back spark plugs on a 1999 grand prix 3.8 v6

Just a tight situation. Small arms help. Best access is from drivers side reaching down between firewall and engine. You will have to find and follow a plug wire one at a time, twist and pull off. ( careful wires if old will break off and a new set will be needed). Using same technique install the spark plug socket on the plug and appropriate extensions to get a good working clearance to loosen plug. Reinstall new plug in reverse order after checking gap. Plugs are in at an angles. You can see them if you really lean in and look down behind engine. It will just be a trial and error on gaining access and changing the plugs one at a time. A plug socket, a 2 inch extension and a 3/8 drive ratchet should do. Don't scrimp on cheap plugs. Good luck

How do you change back spark plugs in 2005 buick rendezous

Most GM FWD's are a pain, but theres a trick. Undo the dogbone that connects the engine to the front frame where the radiator is (some cars/vans have 2, a few have only 1) with a second persons help, push the vehicle forward from the back until it stops (leave the trans in park and the parking break unset) when it stops, lock down the parking brake to keep it from rolling back. Viola, easy access to the plugs. When you're done, put your foot on the brake and then release the parking brake. Slowly let off the brake to avoid having the engine slam back against the firewall, and then reconnect the dogbones. You may need to rock the car a bit to get the bolts back in, but it shouldnt require much.

Engine misses at idle and after shifting (Jetta 97)

Did you by chance check the resistance of your plug wires? They have a tendency of breaking down over a period of time and need replaced. The spark plugs would have told you what was wrong with the engine many times.

Replacing spark plug wires on 1995 Buick Riviera

You need to drain some coolant. Loosen and disconnect water lines by the firewall- the ones in the way of your wire change. u need to get a diagram of the firing order of the engine so that those wires are correctly connected to the coil packs.

Need to change plugs on chrysler1995 la baron

  1. As you have indicated the front side, toward the grill are easily accessable, however the three on the backside or firewall are difficult to reach. They can only be felt not seen. Be sure that you have plenty of time as it will take a while to change them, you will need a
  2. 3/8" ratchet and a universal joint. Take your time and remove them one at a time. I recomend that you also get a set of plug wires as some of them are going to break whenever you remove them. Be sure to check the vacuum hoses when you are finished as it is easy to break or pull them loose.

Trying to change spark plugs

??? ...the spark plug wires are under a plastic guard. The plugs are lower - follow the wires. The ones at the firewall side of the engine are hard to get to...some suggest tilting the engine to access them easier...I laid on top of the engine and got them out.
