86 jeep commanche wont start after wrong hookup of jumper cables
The guy i got this truck from put jumper cables on it wrong and smoked the starter solenoid and maybe some wires.installed new solenoid and all wires,have checked to be sure that i am getting fire on both sides of all fusible links.replaced module in distributor as well as the cap and rotor,also replaced the coil.i am getting fire to the coil from ignition switch but getting nothing out of the coil.there is another relay of some sort beside the start solenoid and it looks like it had a ground wire going to it that needs replaced,didnt think it was relevant to the problem but really dont know what it does.Is ther anything else that may have been affected,is there an ecm?Help,i dont have any manuals to work with.thanks,Steve

Is the anti-theft light lit ? Is the starter relay good ? Do you know what a relay is ? Are the battery cables good ? I would start will the starter relay circuit's if the anti-theft light is not lit.! The starter relay along with the starter relay diode is located in the battery junction box in the engine compartment. The relay is K-22 . If you pull out the relay an look on the bottom of the relay you should see four sets of numbers 30,87 an 85 ,86 . If you take a jumper wire (12-14 gage ) an jump pins 30 an 87 if the battery cables & connections are good the starter will crank . Pin's 85 &86 are the control side of the relay . One of these comes from the ignition switch when is start position an the other goes through the transmission range sensor (park neutral switch) To ground or the PCM if yours has a V-8 . Now if when you jump pins 30 & 87 an nothing happens you have bad connections or the battery cable is bad . You can go on youtube an check out videos on voltage drop testing the starter circuit .
name the fuse. or point a finger at it, there are many fuses.
we can not guess. this.
post a photo or name the fuse.
wont crank or wont start, all cars need to crank first.........
or in my case, push started, or all cars jumper cable started.
If you're referring to connecting jumper cables to start the vehicle on the wrong way you may see smoke and spark, you could melt wires as the ground side does have the ability to handle what the power side can, and damage to components and ECM could occur.
Take a pair of jumper cables,and use the ground side of the jumper cables,and clamp on the negative battery post,and the other end of the negative ground of the jumper cables,to the engine,anywhere that is a good ground,then try and start it,if it starts,then the ground cable on the jeep,is bad,replace it,you might check the connections on the battery post,clean the grey,or black color residue off the battery post,and inside the cable ends to where they shine.This residue acts as a insulator,and will not allow contact.The new battery can have this residue on it,even if it is new.
On an intermittent start problem like this you may be having a starter solenoid issue or your wire on the starter from the key switch may be loose. Or you may have a corroded battery cable or the safety neutral switch may be going bad. Is it a automatic? If it were it would be the clutch safety switch going out. So do the simple things first. Clean cables like the first guy said if that does not fix it locate the starter and if you have jumper cables the next time it does it put the positive lead of the jumper cable on the Positive battery terminal and the other touch to the starter wire with the key in the run position where the big wire on the starter is, if you here it spin it means the starter motor is ok if it don't it is bad or the connection on the starter is loose. Also a bad battery cable could cause this from the battery to the starter next put a small wire into the end of the positive jumper cable and touch the S terminal on the starter if you here a solid clung it means the solenoid is good. So check the connections on the starter and tighten the starter bolts as they may have worked loose and don't have a good ground. So if you want more as stance just post on my question and I will hell p more and if this is more informative please rate
Sounds like you have a bad battery. The quick way to diagnose it is to first ground the negative jumper cable to a metal point that is attached to the car frame of the Jeep. If you can't find one just attach it to the negative battery terminal on the battery.
Then detach the postive battery cable from the battery (you can do this first if you feel safer). Next is to hook up the jumper cables to the car that is going to jump your jeep. Make sure the positive jumper cable is not touching anything on your Jeep first.
If you have friends this makes it easier!
Now you want to connect the positive jumper cable(red) to the positve battery cable on the Jeep. Make sure that the cable ends are not touching the Jeep at all (very important)
Now you want to go start the jump vehicle and make sure the cable still is not touching. Then go try to start the Jeep. If the battery was bad the Jeep should fire up with minimal effort. If you are still getting the same issues then it is either a bad cable or possibly a starter motor that is starting to go (high resistance).
If it starts bring the battery down an autoparts store to be tested.
