I'm having the same problem ? Do you have spark. It not try ignition harness you will also need to replace control module and impulse sender. You can get qaulity harnesses at http://www.linkline.com/personal/dbarton/WireHarnesses.html#OrderingHarnesses if you have a spark, try checking the fuel pump relay under dash on passenger side. a quick way to bypass the relay is to jump the #5 fuse and # 14 fuse...if you do it right you will hear the pump start. If that does it, you need a new relay.
battery need to be at lease 14 volts to be able to start
Over load in circuit? Remove starter and have it checked at auto parts for excessive current draw Dead short to ground in circuit? Over load in circuit? Remove starter and have it checked at auto parts for excessive current draw Dead short to ground in circuit?
Sounds like starter solenoid needs to be replaced
If the engine doesn't turn over at all there are a few things that are possible. Start with the battery ground cable and make sure it is making a good ground and is not broken. Also check the positive cable from the battery to make sure you have a good connection and no breaks in the wire. If these are both good you may need to replace the starter motor. There are brushes inside the starter (yes they can be replaced if you know how to take the starter apart) that will grind down to the point of not making enough contact to start your car. Since you said you had the alternator replaced I'm thinking it probably is the starter because any competent mechanic would have checked the battery cables before replacing the alternator.
No,there is no circuit protection between the battery and the starter. If the starter is causing a dead short to ground, there is definitely something wrong with the starter. Pull it and have it checked. The switch that engages the high current is inside the starter. If the starter is fried and perhaps something melted to ground, every time you engage it you will get a dead short.
It sounds like maybe your starter might be shorted out - a wire could be touching the casing somewhere or it could be something worn in the starter that is letting something go to ground inside. Unhook starter and try putting the fuse in and turn the key if it blows the fuse in is not the starter.
The Chevy starter does not have a ground wire, the starter grounds through the starter casing.
Are you sure the battery has enough juice (13.5volts)? Is the engine locked up? Try turning the motor by hand. If the engine is not seized, take the starter off and bench test it. Recheck your negative battery cable, a very good chance your problem lies there. The same thing happened to my 1995 full size bronco today. I took the battery cables off cleaned each one, and still the same problem. I replaced the starter, solenoid, finally noticed my ground wire from my intake to the fire wall was charred. So I checked my lower battery cable connections and my ground was not connected. I replaced my firewall ground and replaced my battery ground wire and all my problems were solved. Even my dash readings were fixed, I always had crazy readings on my dash (temp, oil pressure and amp gauge) all were fixed with the installation of my new ground wires.
Could be a faulty ground wire. Not very rare to happen
No, the starter casing acts as the ground.
That Thermostat is LOW voltage. IT does not have a ground wire. There is no need for a ground. it only opperates on 24 volts. there may be a green wire but it does not mean it is a ground
Have you checked to see if you have power to starter? If if do then problem is in starter or solenoid. No power then check fuse in fuse box that is in the engine compartment. Check battery cables at the battery & starter. On the positive side of battery there is 2 cables (one smaller) That smaller cable goes to the starter switch then a wire goes from switch to starter. Check that you have a good ground at the starter. Check that the engine is grounded to the frame/body. That will be those wide straps on rear or sides of engine. If you raised the body or replaced the engine then a good chance that the ground has become disconnected.
