Well i drove up to wal mart tonight and while i was driving up there i noticed that my speedometer and my Tach were going crazy and jumping around. The speedo would jump up like 10mph more than i was going and just shoot back and forth, and when i revved the car up ttach would jump along with the speedo . The guy that had this car before me i think jacked with something electronically and screwed it up completely but if yo have any ideas please let me know.
Thanks

Sounds like it is just the battery has a bad cell an no longer will hold the charge. Yes, this will effect everything like the speedo and tach, they are getting voltage spikes. I would replace battery with a new GOOD one and you will be fine. Yes, this is one of those things that does not give you warning before it goes out.

fastss

I agree, if its not cliking when you turn the key then your battery is really dead. but just to be on the safe side tell one of your friends to let you borrow there battery and start her up!!!

I tried to jump it off from another car and it still didn't do anything. Also i jacked the car up and then banged on the starter and it still didn't do anything. This is weird.

Ya thats actually what i was beginning to think but would it cause it to do all that jumping around with the tach and stuff.

Well guys do any of you even have anymore ideas. Ive been searching and maybe my key is just old bc it is the original from 93 and maybe the lil chip thing or whatever on the key isn't connecting or something. Could this be it for my problem??

When you tried to jump it, did you get any indication inside the car that it had power, such as the dome light coming on?

Your battery is dead. take it out and take it to autozone and have them check it. it probably has a bad cell. that is the explaination for all that weird stuff this cold weather kills batterys with a low charge. i just had to replace mine

If the battery is dead then when i tried to jump it off of another car it would have started. Right?

not with a bad cell. I aggree 100% your battery took a crap

You probably would not have been able to pull enough current through your jumper cables to start the car if the battery were completely dead (unless you were using 00 gauge welding cable jumpers). I am a little puzzled why you did not at least hear the solenoid click.
click. Either way, pulling it and having it checked will tell you if you have any dead cells.

Sounds like your ignition switch, i had almost the exact thing happen to me.

You guys are idiots if you think his battery is dead when he has full lights and accessories, and jumping the car didnt do anything.


Are your dash lights doing anything funky? Mine wouldnt all come on until the key was in the "start" position.

Sounds like a loose battery cable to me. Just happened on our winter beater. All the lights worked perfect, but when you tried to turn it over, NOTHING. The battery will make enough contact to power the lights fine, but when you try to put 600+ amps through a connection that's not fully seated, it'll burn the spot making contact just like a welder and you'll get nothing. Disconnect the battery, clean the terminals, and reinstall them. I bet that's your problem.

Had the same issue with ignition switch melting under the dash...happened twice (got a bad one the first time I guess)....

Did you get it resolved?

Before you do anything, check your VATS. I believe there is an easy way to do it, but the wires going to the key are very very small and get frail with time and break. When my VATS went out, everything in the car worked but the starter solenoid wouldnt engage. Try this...
