    When you say "I turn the key. nothing happens", do you mean literally nothing happens, or the engine turns over but doesn't start? What about any other noises when you try to start it?

  • Tom Walsh Aug 08, 2013

    There are no noises. All lights come on, the navigation screen boots up, and nothing happens when I turn the key. No engine sounds at all.

Before blaming the starter make sure the battery is fully charged. It should be around 13V.
Starter circuits for the most part operates in the following way. Turning the ignition key supplies power to a relay situated in the engine compartment which in turn activates the solenoid on the starter which powers the starter itself.
Make sure your vehicle is in Neutral(Manual gearbox) or Park(Auto box) Locate the starter motor. On the starter there is another cylinder like object called the solenoid. There is a thick red wire running from the battery connected to this. There is also a much thinner wire which activates the solenoid. To test the starter run a wire from the + on the battery to where the thin wire connects on the solenoid. (ignition must be off) This should activate the starter and turn the engine. If nothing happens the starter is probably at fault. Before removing the starter make sure that the engine is properly earthed as this could also give problems.
If the starter does kick in the problem is further "upstream" Most probable cause would be the relay. If you can locate it, replace since it is relatively cheap.
Starter repair is best left to the experts. Get a quote for a new starter before you have the old one repaired. You'd be surprised at how many times it turns out that replacement costs the same as repair.
Let us know if you've solved the problem.

You either have a bad ignition switch or a bad startermotor. You can have the starter motor checked at your local auto parts store. Please rate my answer.

Try taking the nuts off your starter and cleaning your connections with sandpaper shoot wd-40 on them then tighten the clean connections back together. Make sure you DC the battery first.

90 YJ 2.5l Cranks but will not start. tried starting fluid but still nothing


Run basic troubleshooting tests. Spark to plugs when cranking? Compression test? Fuel pressure at key on? I don't know this engine, but if it uses a timing belt these can fail when you try to start a cold engine.

Your engine computer is bad. Either you need to open it up and replace the three power caps or you need to get a new computer. The computer is not sending current to the relays. That's what's causing the delayed check engine light on your jeep.

Ignition on 88 jeep yj not working


sounds like your ECM might be bad. Is there anything else that will turn on besides the lights? It could just be a main fuse. I'd start at the interior fuses if any and then go to the main fuse block and check for any loose wires or blown fuses first.

93 wrangler yj electrical wet


You have likely fixed this by now but if not, you will have to use some dry rags and dry off everything!!!! Use compressed air wherever you can't get to (or at the least, a tire pump) Vehicles are not designed for use in the water. If ;you want to do this, get with some off road clubs that can give you tips on waterproofing stuff!!! Just to somewhat "wheatherise" my stuff, I wipe down ignition components with a rag saturated with wd40&silicone spray. I don't think this will work in deep water but it sure helps in very damp or rainy weather! You can also make splash guards out of very heavy tar paper or sheet metal that you can place under the front, but be careful where and how you place and secure it so nothing interferes with steering etc.
