:confused2: battery is good has 12.5 volts, replaced starter and it was good for 5 days now it won't start agian. When I try to start it it just clicks and thats it. Is this a wiring problem or something else?? Please if u can help? The starter i bought was actually a starter assembly included the soleniod, and my battery is only 5 months old.
How much voltage was across the battery with the engine running? Normally it should be around 14v. If it is lower, the alternator is not charging enough. Can you get it started off a jump start?
Take the starter off and have it tested. Is it brand new, or rebuilt? It is possible that your new starter is bad. I know because this has happened to me.
If you can get it started, take it to NAPA or some other parts store. They have diagnostic equipment that they can use to check the condition of the starter, battery, and alternator while these are still on the vehicle. I have had them do this for me several times, and it's always free. Just be sure you leave the engine running while you go into the store.
Two things I'd check for:
1) I know you said the battery looks good @ 12.5V, but how old is the battery? I had this exact problem on another vehicle many years ago. Battery tested okay (voltage), but had a bad cell inside and couldn't deliver the current/power (cold-cranking-Amps) required.
2) Starter solenoid. Big fat coil/capacitor, basically. Probably separate from the starter in this case (someone jump in here and correct me!), which is why a new starter didn't fix it. For me, the solenoid wasn't a cheap part: it happened to be integrated with the starter assembly on my other vehicle when it went bad - had to buy a whole new starter assembly. "Go Mopar." :cuss:
I agree, the battery could be the problem here. But it could be the alternator also. Since it lasted for 5 days, I would suspect the alternator more at this point.
The solenoid is attached to the starter on GM products. It is basically an electro magnet. It is not a capacitor. It is easily replaced on these starters, but it does not sound like the problem in this case. You would probably hear the starter motor spinning if the solenoid was bad.
It is always a good idea to keep battery cables clean. Dirty cable problems usually crop up when the weather gets cold at the end of fall, but can occur at any time if they are bad enough. Good suggestion.
