Not cranking, replaced starter, battery, ground cables.

[kidwiththelaser]

okay, i dont know what is wrong with my car now.

It didnt want to crank over at all, I hear it whining when im trying to crank it over. And I hear the relay kick in.

So I took the starter out, and it tested bad, so I replaced it.

Then it worked on and off for about a week. So I looked at the battery, and I noticed that the negative battery post, was broken!!

So I replaced the battery, and then it worked pretty good for about a week.

And now it doesnt want to crank over again!!!
So I replaced the ground cable, because it looked like it was a bit corroded (sp?).

But that didnt work at all either!

Does anyone have any ideas??

Thanks alot!

Fuel pump? Ignition switch? Check your fuses/relays. Make sure the battery cables aren't loose on the posts (or grounding out...).

I assume you still hear a click, whine, or something from the starter.
Poor cable connections from the battery to the starter is the #1 cause of starter problems. I'm talking the big cables. The ends can get corroded, dirty, not tight, or partially broken (inside) where the cable meets the terminal. If there is even 0.1 ohm resistance in the path from battery to starter, it will drop so much voltage when you crank, that there won't be enough voltage left at the starter (needs to be more than 10 volts at the starter). Remove and clean both ends of these cables (and what they connect to) and battery posts with sandpaper and tighten securely. Do both the battery positive to the starter and battery negative to engine (connection to engine must also be clean/tight – this is usually to a starter case bolt). Also try wiggling the cables to check for breaks.

After doing this if it still won’t crank, measure the voltage across the starter itself while cranking. If it's less than across the battery posts themselves (while cranking), one of the cables is your problem and needs to be replaced. You can measure the voltage drop across each cable (from one end to the other) while cranking to find out which - should be close to zero. Or what’s easier is connect a battery jumper cable from battery negative post to engine block. If it now cranks your negative cable/connection is bad. If not, connect the battery jumper cable from battery positive post to starter positive post. If it now cranks your positive cable/connection is bad.

Wow!

Thanks alot, ill test all that either later today after studying for my test tomorrow, or ill do it tomorrow.

Thanks alot man!

Ill get back to you guys, and let you know what it was!

Well I checked over all the connections, and I found that the little wire that clips onto the starter was disconnected!!

So that was an easy fix!

Thanks alot luv2rallye!!
