Check the fuses and the relays. and finally the ignition switch, its rare but the little wires get loose or broken, and send no electrical power to the switch

SOURCE: 1990 ford f-150 nothing happens when ignition is turned on

Solenoid was not mentioned as replaced.

If it was not part of new starter...that's the culprit.

Ignition switch (smaller wire) activates the solenoid (heavier wire) which in turn activates the (high current) starter.

If its not on the steering column, you can figure it out using an ohmeter on the switch leads. Actually, you could figure out the one on the column that way too! just think about what the switch does in each position and attach wires that do it to the post that does it! IE: starter solenoid wire goes to post that is hot when key is turned all the way to start. Main hotlead is the one that is common to all switch positions. run and accessories is to the post that is hot with key on, accessory only is the one only hot with key turned backwards.

There is also an ignition relay, a coil, and the wiring harness it's self. Check to see if the ignition can be by passed by using a test light first to find the hot side of the ignition fuse. See if there is power there it should be constant all the time but it only makes the connection when you turn the key. If it does it's probably your relay. You are aware that there is two fuse blocks for the ignition. If there is no power to either fuse block i would buy another ignition switch (you can always take it back).. and if still nothing i would replace the harness.. hope i could help. oh one other thing check the ignition module.

Have a 99 Jimmy GMC when u hook battery up I can not get power to itintion switch fus box r inside if car period battery is good I mad sure of that


Do you know how to read a wiring diagram ? Go here http://www.bbbind.com/free_tsb.html free wiring diagrams . Enter your vehicle info - year , make , model , engine etc... Under system click on electrical distribution , then under subsystem click on power distribution .Then click on search , six blue links will pop up , click on them one at a time . See where ignition switch gets it's power . The ignition B fuse 50amp located in the under hood fuse box, supplies B+ voltage to the ignition switch .Plus Ignition C an ignition A fuse's also power ignition switch .

I need a wiring diagram for a 2002 chevy s10 4 wheel drive 4.3 for the starter to the switch


If the truck cranks over you have voltage at the ignition switch ! From starter to switch , First off starter to what switch ,ignition ? There is a 175amp fuse that supply's battery voltage to the power distribution center - fuse box under the hood . On the lower right side of the radiator support, below the battery !

My honda marks the battery even though we bought a new battery and alternator. And nothing electrical inside the car turns on. What is the problem?


Check your main or maxi fuses. If an older car, there may be fusible links between the battery and the power distribution. There should be ignition fuses that supply power to the ignition switch. These fuses would be hot at all times, so take a test light, ground it to battery negative, and check if the fuses have power to them. Pull one fuse out, touch the tester probe into both terminals the fuse plugs into. If one terminal lights up the test light, then that fuse is getting power. If the fuse is good, power will pass on to whatever is on that circuit. If it's an ignition fuse, the ignition switch should have power to it (if the wiring is good), and turning the key to on, should send power out to the dash and to the engine.

Be systematic-follow the power from the battery to the fuse/relay box to the ignition switch. Don't forget the importance of ground in any circuit: if a circuit doesn't work, check power and ground. Check your battery ground for a clean, tight connection, from battery negative post to frame ground.

Chevy Tahoe Intermittent No Crank


I will try to help, powell. Your start circuit from battery to ignition switch to starter-and back to battery. You may need to check every thing here, including the grounds, for a loose connection, or just possibly a failing part.
If only complaint is intermittent starter action, and no other problems with ignition switch, let's assume switch is good, so battery to ignition switch is good. Now from the switch, a yellow start wire goes to the instrument panel fuse block, to "crank" fuse #8 (10 amp), from there a purple wire goes to the safety switch. If manual it is a clutch pedal position switch (simple on/off switch-when clutch down switch is on). If automatic, purple wire goes to Transmission Range Switch on the transm.-in park or neutral the purple wire has continuity in and out of switch.
From that switch, the purple wire goes to the starter relay (under hood fuse-relay center). Now the relay: purple wire in start will energize the relay- wire goes to coil side of relay, and then coil side goes to ground. On relay power side, the power feed is a red wire-and it is the same red wire that initially sends power to the ignition switch. A 40 amp fuse in fuse-relay center sends power to ignition switch, and a splice goes to the starter relay as the power feed for relay. When relay is energized, contacts close, and power is sent from relay to the starter solenoid, again on a purple wire. When solenoid contacts close, starter motor is connected to the big battery cable on the starter.

There is your start circuit. try a new or different relay, try a new or test the clutch switch (or transm. range switch). Buy a $5 test light and use it to check where power is lost when starter won't operate. Hold key in start and check if fuse #8 is getting power. Check the safety switch, with key held in start, the purple wire should be hot. Check if relay has a power feed (pull relay out and check terminals) and if relay coil has a power signal in start. Check the relay's coil side ground. If that ground is intermittent, relay won't work.
When it won't start, use a test light, you should be able to find it.
Good luck.

Where does the ignition switch and fuse panel get its power from? 4 dead fuses, not blown.


I have found with these Crown Vic's,especially police cars,they manage when the get in accidents to hit the right front of the cars and when they do they damage the wiring harness. The rain,salt,snow get in the harness and you eventually have problems. Look under the car in front of the right front tire and you'll see. Good size wiring harness. Look at it for damage,or sometimes you'll see like a light green dust coming out of the harness. Usually where I find my breaks,shorts or opens.

92 plymouth voyager wont start and nothing work the windows wont go down the lock and unlock button does nothing idk what the problem is i had the battery tested and the battery is fine what would cause...


Nothing works? How about the headlights, do they work? If yes, then start checking all fuses in the Power Distribution Center or Box under the hood. If no, then look for a bad maxi-fuse in the PDC, and check for a bad fusible link between the battery and the PDC. The battery positive cable goes to the starter, but a pigtail lead off the positive would go to the PDC, to distribute power to all the various circuits on the car.
When you turn the key to on, does the dash light up? If yes, at least power is getting to, and going through the ignition switch. One could then check for power on the starter solenoid wire when key was held in crank or start position.
If nothing when turning key to on-no dash lights, nothing-then check for an ignition fuse in the PDC. If fuse is good check for power being available at the ignition switch connector. If no power there, check wiring between PDC and the ignition switch-if power is up to the switch, but nothing happens with key on, no dash or warning lights, then could have a bad ignition switch.
It just sounds like a maxi-fuse has blown, or a bad fusible link. Good luck.

No starter response when key is turned over. new starter and battery. all fuses and relays good. only thing left is ignition switch?


The starter is malfunction at this time. it could also be a ignition issue as well. here is a quick starter test procedure that will help you troubleshoot a bit.

Step 1
Check for 12 volts on the large wire attached to the top terminal on the starter relay. It should have battery voltage. If not, the battery, terminals or wire is bad.


Step 2
Check the small wire on the solenoid for power when the key is in the start position. Remove the small wire on the solenoid and have a helper hold the key in the start position. Check the wire for battery voltage. If there is voltage, the starter is bad. If there is no voltage, replace the wire.


Step 3
Check the fuse in the fuse box under the hood on the left fender well. If it is good, check the relay by pulling it out and checking for power at one terminal with the key off. If there is no power, the problem is in the fuse box between the fuse and the relay. If there is power, have the helper hold the key in the start position once again and check for power at another terminal from the ignition key. If there is power, the relay is bad. If there is no power, the starter circuit is suspect.


Step 4
Check to see if there is power to the neutral safety switch if there is no power at the relay. Use the voltmeter to check for power with the key in start. If there is power going in, check for power going out. If there is no power going in, the security system or ignition switch is suspect. If there is power going in and none coming out, the switch is bad. If there is power coming out, the problem is between the neutral switch and the relay.


Step 5
Remove the cover on the bottom of the steering column. Check the solid yellow wire for power when the key is in the start position. If there is no power, the ignition switch is bad.

After changing the starter and alternator and installed a new ignition switch my 1997 Nissan p/u started up fine. Drove it around town, stopped, turned off the engine and it started again right away. Drove...


Check and make sure you are getting power to the ignition switch and to the stator wire on the starter. Turn the key on and and measure the volts going to the starter on both wires. You should a atleast 12 volts going to the stator wire and to the main wire from the battery. If you are not getting power there it could be a fuseable link in the power wire from the ignition. I noticed that you replaced the ignition switch make sure the rod from the key switch has not come out of the switch.
