ok i was driving along testing my car after i fixed my intake and exhaust leak and im goin through the gears, watchin my tach. then at about 4-5 grand in 3rd my tach drops to zero, engine speed stayed same just tach. then my tach flies back up to 4 and it just flew all over the place for maybe a second, then just dropped ot zero. it felt slower after that happened and my stereo also quit at the saem time the tach f****d up. so i pulled over half mile from my house turn it off( i dont have a ebrake to if i want it to stay i have to turn it off) and i was gonna take a look under the hood, not sure wtf i was lookin for. but then when i get back in to start it up, my batterys dead. and when my dad came to jump it my fuel pump wouldnt turn on. WTF happened to my car?!?!?!!?!?!?!

i wasnt even sure what to search?
