Could be neutral safety. You can unplug the connector and use a jumper wire to test it. Could also be igniton switch,but neutral safety is more common failure and cheaper and easier to replace.

Motor don't turn nothing dash lights and head lights 1985toyota pu

Do the gauges and warning lights work with key on? If not, check fusible links, AM1 for ignition key power. If the gauges/warning lights work, the key switch has power, so you can follow it to the starter solenoid. The start wire out of the ignition switch is a black/white wire, this is the hot wire to the solenoid, and only has power when key is held in start. With automatics, there is only one switch-a neutral start switch- between the ignition switch and the solenoid on the starter .

With a manual transmission, the black-white start wire goes to both a starter relay and a clutch start switch (on the clutch pedal), those two work together to send the power on to the starter solenoid. So, no crank, good battery, power to key, follow the black/white wire, the start relay and the clutch switch, to the starter solenoid- a hot wire there turns the starter motor on.

2000 chev wont start at key

I think the purple wire (or maybe the yellow) from the neutral safety switch goes to the coil side of the starter relay, turning it on so power is sent from there to the starter solenoid. You could check for this signal to the relay with a test light. The key must be held in start while you probe the other two terminals for the relay. If the signal is there, either a bad relay or the coil side of relay is not grounded properly. It is possible that the coil side ground is the neutral safety switch-grounding the relay's coil side only in park or neutral-in which case the nagging light on shifter (between off and run, it only works?) may be telling you the safety switch is the problem.

You may need to look at a wiring diagram, Greg. But the starter relay is the last component in the start circuit before the starter solenoid. From battery to ignition switch to "crank" fuse to neutral safety switch to starter relay to starter solenoid to starter-and back to battery through ground. That is the start circuit. Just that the wiring tying them all together makes it complicated.

How do you replace an ignition switch in a Lincoln Navigator?

Don't believe it would be the ignition switch. It sounds like the starter relay may be stuck in the on position. Find the starter relay and pull it out. One terminal would be hot at all times-use a test light grounded to engine block and probe the relay terminals. Should only have one terminal showing power. Now have someone hold the key in start position. Now you should have two terminals showing power, and when key is released to the run position, the second hot terminal should stop showing power.
If it works like this, try a new relay, or a known good one. If second terminal still shows power without key being in start (cranking) position, then it may be the ignition switch or the wiring and connections between the switch and the starter relay.
You will keep burning starters out till fixed. Starters that are run more than a few seconds at a time will get too hot and burn out.

Help identifying problem starting hyundai excel 1996

Sounds like a problem with the wiring between ignition switch and the starter. Something like a weak connection, an obstinate switch that is old and sticking, or a component that is starting to fail. There aren't that many parts in the starting circuit, but until you find the problem, you may end up checking them all. If all other electrics are good, then it is confined to the starting circuit-which starts with the start wire out of the switch, and ends at the starter solenoid on the starter. With a test light or a voltmeter, one could begin at either end and trace the signal through the circuit. Easiest, I guess, is take a test light grounded to the engine block or to the negative post on the battery, and check for power on the small wire at the starter solenoid while someone holds the key in crank position. Do this when you turn the key and nothing happens, starter won't turn. If you have power there when the starter wont work, pretty obvious that the solenoid is not working all the time-they do get old and worn, and will stop working. The starter will have to be removed to replace the solenoid-some people just get a new starter with new solenoid attached and ready to install. More expensive than just a new solenoid, but then you don't have to change out the solenoid on the starter.
OK, go back to test: the car won't start, you check for power to starter solenoid with the key in start position, and you find no power. Now it gets more complicated: a wiring diagram for your excel may be needed. Generally, the hot start wire exiting the ignition switch will carry the signal through a starter relay and a clutch switch (on manuals, on automatics it would be the park/neutral switch and possibly an inhibitor relay-depending on the wiring set up). A tech or mechanic would begin by making sure the start wire out of the switch shows power in start. If not, replace ignition switch. If good, follow the wiring diagram to the next part, maybe the starter relay, and see if the start signal is still good. Pull the relay out and use your test light: with the key held in start, probe all terminals of the relay. Two should have power. One would be your start wire, the other would be the (hot at all times) feed for the relay. You could tell which is which by finding the one hot terminal when key is not in start. If only one terminal at relay is hot, and it is the feed for the relay, go back! Start signal is already lost. If the feed wire is not hot, check battery connections. If good, the feed wire would come from a fuse link just off the battery or a maxi-fuse in the distribution box under hood. If you have two hot terminals, follow the start wire on towards the starter solenoid-you are done with starter relay, unless there is a problem there with the relay itself or the other two terminals at the relay. One terminal would carry the feed wire on towards the starter when relay is energized. The other terminal may just go to a ground or it may ground through the clutch switch If you are good to this point from the switch, you would just continue checking based on your readily available wiring diagram-hah! But really, you could find a diagram in a repair manual-check your library. These can be very frustrating problems, sometimes hard to find, sometimes easy. Post back if I can be of help. Good luck.

2005 dodge ram 1500, will not turn over. Battery is hot and tapping on starter doesn't help.

What you need to do is check to see if your getting current coming from the key switch to the starter. it's the thinnest wire that goes on the startex, that little round thing on the starter. if no current check the fuses you will see one as ( ST ) that is staring fuse. If fuse is ok then you check the starter relay and if that is ok then you might have a broken wire. to make sure the starter is working you could put the van in park and connect a jumper lead to the startex where the small wire runs to the starter and touch the next end to the B+ or 12 volts side of the battery and if the starter works then you have a broken wire.

Battery good, alternator, starter all good. Fuses good. When turning the key to start there is no power at all. no

Just concentrate for the moment on the battery, starter, and ignition switch. Your 92 jeep is a complicated marvel, but all you need to do is get the starter turning the engine for all those automatic things to happen and turn it back into a mobile jeep.
As long as you have battery power at the switch, and even bigger battery power at the starter, and you connect the three of them together...instant bingo, the engine starts, or should if everything is working right. If I understand you right, you do have power to the switch, just nothing in start, or you 'd have noted that. Check engine light on, and warning lights and gauges work, yes? Then the switch is working that much, anyway. The switch start position should transmit power to the starter on the small wire that is on the starter. You can check for power there when the key is held in crank (start). Easy to check with a meter or a testlight. You stated battery and starter are good, so if the cable connecting them is good and tight., your problem may be in the start circuit from the switch to the starter (starter solenoid, to be exact). So it's ign. switch to starter relay to starter (solenoid).. Check for power on that path. Quick check at starter relay: pull the relay out (in the power distribution box) it connects to 4 terminals.. One terminal should be hot all the time. check with testlight. If nothing there, check the 40 amp fuse or battery connection or wiring. If one is hot, then have someone hold the key in crank. Now 2 terminals should have power. If not then ignition switch or the neutral safety switch or the wiring between them needs diagnosing. If two terminals do have power, try another relay. maybe yours went out. If a good relay doesn't help, then starter solenoid or starter or your wiring needs further troubleshooting. Hope you find it, over...

Hi, the problem is either with the crank fuse, ignition switch, safety interlock or the starter relay. First check the fuse (in the instrument panel fuse box). Can you hear the starter relay click when you turn the key to start? You may want to probe the relay socket with a 12 volt test light to see if the ignition switch is working. If it is, there will be 2 hot terminals in the socket when the key is turned. The relay is in the relay box under the hood. Connect your test light clip to chassis or engine ground, pull out the starter relay, and have someone hold the key in the start position while you probe the relay socket terminals. If there are 2 hot terminals, replace the relay. If there is only one hot terminal, try bypassing the interlock switch. On a manual transmission, the interlock is above the clutch pedal. Pull the connector off it and connect the terminals in the connector using a large paper clip.
If you have an automatic, pull the connector off the range sensor and connect the green and purple wires using a large paper clip. I think it's on the tranny. See picture of it below. Please let me know if you have questins, and thanks for using FixYa.

99 Saturn won't start

I would suspect the starter solenoid or the starter. I may be telling you something you already know, so if I am, bear with me. When you turn the ignition key to start the car, you apply 12 volt to the starter solenoid (which is physically located on the starter). The solenoid is actually a relay that applies 12 volts( at very high current) to the starter. Since you are not hearing any clicking when you turn the key, I suspect the solenoid. BTW, when you get a starter it usually comes with a solenoid already atteched.

Hope this helps Good luck Loringh
