According to Dan B. on answers "missing spacer. The heavy wire from your alternator goes directly to the battery. If that wire is grounded, you are sending battery power directly to ground - blowing that link. That wire is not a ground wire - I don't care what the color of the insulation is - black or red. "

SOURCE: no power to ignition 96 camero dl

Check the wires to the distributer or to the modules could be poor or no conection. If you can turn the car over but no spark it's probably something to do with ignition, distributer, module, or wiring to the ignition.

SOURCE: wont start

You could try replacing the two fusible links down by the starter. They look like two black pieces of rubber on the wires. Just cut them out and splice the wires back together. If that's your problem it should start. If you unplug the neutral safety switch from the tranny the car should start if that is the problem. Hope this helps.

SOURCE: fuel injecter fuse blow imeditaly when ignition turn on

sounds like a short in the wiring from the fuse and the fuel injector junction block. GM like most fuel injection systems control injector firing by the computer providing ground to each injector in pairs or individually. The fuel injector fuse provides power to the injectors using splices therefore enabling one wire to feed 6 injectors. A shorted wire at any of these wires will blow the fuse. On one rare incident I found a faulty computer caused the fuse to blow. A shorted injector will just cause a rough running problem due to the injector stuck either open or closed.

My 2001subaru forester won't start I changed the bat. and nothing no headlights no radio but the emergency flashers work and the door chime.

If jump starting one hooks up backwards, even just a moment, it is possible to blow a fuse or fusible link, and on some cars even damage the ECU or other components. Check all fuses, then fusible links. Good luck.

I have a 95 honda accord dx. When i put the key in and turn it nothing happens. All my dash lights come on but nothing trys trys turning over or anything. I was told by a handful of mechanics and people at...

Check to see if you have voltage to the starter if you do try tapping the solenoid while someone cranks it if it starts change out your starter if you have no voltage to your starter start to look for a fusible link that goes to your starter chances are its blown. A fusible link is going to look just like a regular insulated wire but acts as a fuse and blows just like a fuse check the wires to the starter I usually pull a little on the wires to see if the insulation will stretch if it keeps stretching then that's the fusible link that's blown and will need to be changed out. I have seen this on many vehicles where everything works but the starter will not turn over. sometimes the fusible link is located down by the starter and other times its under the hood next to other fusible links you just have to find it let me know how it goes.

No power electric problem

No, not a relay. The ignition switch is too central to the electrical system. It sends power out to most circuits on the vehicle-those that are designated "hot in accessory, run, start" or some that are only "hot in run or start". Being central, it requires a direct battery source, a "hot at all times" source. Anytime the battery is hooked up, the yellow wire to the ignition switch is a hot wire (actually 2 yellow wires-they splice off before entering the switch or before entering the electrical connector for the switch). The source is Fusible Link M on the starter relay, one of many Fusible Links there, and tied in with the positive battery cable connection. So also, the alternator link is there, so is the headlight switch, the hazard and brake lights Fusible Link, and some others that do supply relays (fuel pump, eec relay, etc.). But Fuse Link M is dedicated to only the ignition switch. If you have no power at the connection to the switch, look at fuse link M. It should have some identifying legend or mark.
Where you saw the sparks, was it at the switch itself or the electrical connector to it? Either way you will have to check. If at the switch, It could be a bad switch, and may have also blew out the fusible link. If at the connector, check if it damaged the connector and is losing contact. Post back with what you find. Good luck.

Battery got connected backwards truck will not start

Yes this is a common problem, it's been asked here before. You end up blowing a lot of components that way. Now to hunt down what they are. Fordexpert said this last time> Could be fusible Master link which is sometimes around battery and runs to fuse box. Looks like fat wire and melts connection from battery to body. Another possibility is the wires to the Ignition switch. Most are inactive until the Ignition is turned on, but with reversed polarity things can happen. Fusible Relays. You are lucky most of your truck is not computerized. But there may be an Ignition relay and a Light relay. Some had a grey module on the distributor. Test for the fusible link first and see if it has melted. If you have power to the fuse box, check that there is power on the power side of the panel.> If your vehicle is computerized it could have blown the computer too.

30 amp Starter/Ignition fuse keeps blowing when i turn the ignition key. The instrumentpanel lights are dim and then the fuse blows.

I am assuming you are talking about the circuit that powers the key switch. I'm showing a fuseable link to the starter relay instead of a fuse.
If it is the circuit that powers the switch, I would disconnect the switch and see if the fuse blows as each circuit is powered one at a time using a jumper wire. You can get 30amp circuit breakers that plug into the fuse slot to use while you are testing circuits.
You may need a repair book or shop manual to find out what is powered by that fuse since it is most everything on the car.

Check your fusible links (wires that act like a fuse). The fusible links are located on the battery post on the starter, and some are located on the positive battery cable.

Car starts up and runs for afew mins. than it shuts off when you turn the key it doesn't even turn over it is dead the starter doesn't even kick in.I changed the ignition module in the distributor it...

Well the ignition module could cause it to die but it wouldn't cause the starter to not crank. Sounds like power feed to the ignition switch. Also it would run with the ecm fuse blown, it would just run in back-up. Have you checked the fusible links at the starter. Make sure the 5/8 inch nut is tight on the starter. The positive battery cable and the fusible links should be hooked to it.
