okay so yesterday i was putting interior lights in the car and when i was finished i turned the key and it wouldn't start up. i turned the head light switch on to see if the lights i just put in worked but nothing happend the head lamps came on but no lights inside the car came did. so the car wont start and no lights are comming on so i took the lights i put in out to see if that would help. after i took them out i noticed the only way for the dash lights come on is by turning on the back winshield wiper on. at first i thought i crossed a wire but i looked at all the wires i messed with and they where perfect. i jumped the car to see if it would start and it did but when i put it into any gear if feels like the tranny is going to fall out and when i accelerate it takes off much slower like 15 seconds just to get up to 20 mph

what could be the problem please help!

 

Have a charging system check. Check the battery and alternator. Unhook the battery for a couple of minutes and reset the ecu.

 

check the earth terminal on the battery
