Have you replaced the negative battery cable to the engine? Sounds like you have a lack of engine ground issue, then it seeks a ground wherever it can.

Kia sedona problems starting


Kia Sedona known for electrical grounding problems. Before spending any money, follow thick wires from battery negative terminal to body and to engine block. Disconnect and clean each connection, use oscillating sanding tool and #400 grit to polish the surface where negative wire connects and to polish the terminal end of the wire too. If unable to find a negative battery wire to engine block or transmission, buy one at Walmart $8 and install. You may need to replace your negative battery terminal to accommodate another wire. Most likely by cleaning the grounding or providing an express engine ground, your original electrical problem will have disappeared along with many others you may not have noticed. Be sure to remove and clean both battery terminals and connectors too.

  3. Disconnect the ignition coil wiring from the coil being tested. Fig. 2: Disconnect the ignition coil wiring from the component being tested — 1MZ-FE engine 89552g59.gif

  4. Insect the primary coil resistance using an ohmmeter. Measure the resistance (cold) between the positive and negative terminals. Resistance should be between 0.54–0.84 ohms. Fig. 3: Attach an ohmmeter to the positive and negative terminals of the coil — 1MZ-FE engine 89552g60.gif

  5. If the resistance is not within specifications, replace the ignition coil.
  6. Reattach the ignition coil wiring.
  7. Reinstall the V-bank cover. Push on the cover until a click is felt, then tighten the cap nuts.

Where is the starter located on a 2002 Chevy Suburban? How do I replace it?


    Removing the Starter
  1. Step 1 Open the hood to access the engine compartment. Disconnect the battery by unscrewing the positive and negative terminals. This will prevent the risk of electrical shock.
  2. Step 2 Crawl under the passenger side of the truck and locate the starter. The starter is positioned between the transmission and the engine.
  3. Step 3 Unbolt the negative and positive wires from the starter with a socket wrench. Take the nut off the stud and pull the wires off the stud. Repeat the same for the positive wire.
  4. Step 4 Unscrew the two bolts holding the starter to the frame. Wiggle the starter to work it free from the flywheel.
    Installing the Starter
  5. Step 1 Position the new starter onto the frame. Tighten the bolts to secure the starter in place.
  6. Step 2 Unscrew the nut on the positive stud and push the positive wire down on the stud. Tighten the nut on the stud to secure the positive wires.
  7. Step 3 Unscrew the nut on the negative stud. Push the negative wire on the stud and tighten the nut to the stud to secure the wire.
  8. Step 4 Connect the battery cables to the terminals. Ensure the positive wire connects to the positive terminal. Ensure the negative wire connects to the negative terminal.
  9. Step 5 Start the truck to ensure the starter is functioning correctly. The starter should catch as soon as you turn the key and start the truck.

The thicker negative wire should go to the engine for a ground. You should be able to move the wire around to different points on the engine and you should find where it broke off of the end terminal.

Does the car seem to be "turning over" slower than normal?
