Default Need help!

2 weeks ago I set up my battery the wrong way and it blew a fuse. I replaced the fuse and still the car won't start. I only get one click from the starter when i turn the key. I bought a brand new starter checked all the fuses and tried to jump the car several times. What will fix this problem and how do I do this??? The throttle body clicks rapidly when i turn the key into an on position without trying to start it up. Don't know if this helps just looking for some help ASAP

There may be more than one fuse that can pop. Have you checked the fuse in the engine compartment, specially the high current one (ends are bolted down).

Just a suggestion, you will get better help if your title is more explicit.

(1993 Lexus Sc300 automatic)Ive checked all the fuses at this point. Inside the car and under the hood.When I hook the battery terminals back up the negative doesn't make much of a spark anymore just a little crackle. Theres no way the engine is seized up It was driving fine before this happened. I think i need to change the wires in the starting circuit. ANY other advice?

Terminology just gets me ... 'turn over' -> crank shaft turning over
I assume you mean engine is not catching

Next step is to check for a spark
Next would be fuel
and then timing


Go in that order and you will find out what is not working.

You may have messed up the computer or fuel ignition delivery electronics.

I got it to the point where it was close to starting tried it several times but wouldn't fire up. Im charging the battery but when i attempted to start it i was jumping. I tried it at least 10 times and now when I turn the key it only makes a dud noise and it won't crank. Its different than the starter clicking noise. Diagnosis ?

Try a spare ecu.

If its rotating then its compressing air.

Check if the fuel is priming. If the pump comes on and there is pressure at the regulator.

Check that your coil works.

Thats the only thing I could think of.

Car is on verge of starting but it must not be getting enough gas. Tried starting it and it rumbled like it was about to start but went back to only squeaking (the noise when you first turn key). I just changed spark plugs might this have something to do with it?

You can fry the fuse panel, replace that or your ecu... You can also remove your ecu and open it up to check... The fuse panel also has a possibility of frying (its by your front left foot in driver, I've had mine replaced
