Ok so today i was driving back home from work as usual listening to my radio when all of a sudden my radio starts flickering and then it shuts off, then i look at my dashboard and my ABS light turns on all of a sudden and then my car starts misfiring. I barely make it home and as soon as i come to a stop my car shuts off... i try to start it but all i hear is the sound of a rapid clicking sound.. no engine noise or anything just that rapid clicking sound.... It was only 4 days ago i spent 600 replacing a fuel injector and some other stuff on it... has this ever happened to anyone or does anyone know what the heck is wrong with my baby? plz help thank you

Stuff tends to go haywire when your battery or altenator is dead.
Get a new battery, and get an auto electrician to check your altenators output.

Moving this to Z32 technical.

It's the alternator. 90% sure (10% maybe loose/shorting wire). This exact thing happened to me when my alternator took a crap. The Air Bag light came on to tell you that the alternator wasn't putting out the proper voltage that it is supposed to. The clicking sound is your starter solenoid attempting to engage, but not having enough juice to engage and stay engaged, so it's rapid fire engaging/disengaging (very bad for it).

What to do:
1. Test alternator
2. When you find out that it is the alternator, replace it
3. Charge the battery/ jump the car to get it running again.
4. Let car run for a while to fully charge battery (take it on a short cruise near your house)
5. Drive car like nothing every happened

And don't try to keep turning it over while the battery is dead. That is very, VERY hard on your starter solenoid.

Can the alternator problem also be cause of the misfiring ?

Agreed. Also, when you pull off the alternator, make sure it isn't wet from either oil or transmission fluid. If it is, fix that as well or you will just keep replacing the thing...

Leaky cam seals or PS hose can leak onto the alternator and ruin it..
If the alternator is covered with oil or ps fluid fix that first

I have a s13 with what I came to find a common problem of my brake light fuse and dash light fuse blowing repeatedly, (and even one time my fuel pump relay which left me stranded at a 7 11 for hours once) when I had the car running yesterday I disconnected the battery and the car shut off, commonly meaning the alternator is bad, could this mean that the alternator could be the cause of all this fuse blowing??
