So my car is dead. Literally. When i turn my key NOTHING turn on. Not my head lights, inside car light, brake light nothing works and my car doesnt start. Its not a dead battery cuz i checked it already. I basically dont know what to do. Does anyone have any ideas of what the problem can be. Not my ecu, not any fuses, not even the relays. Any suggestions?

 

check your fuses

 

Might be a main relay, what did you check with the relays to prove that they aren't bad?

 

Definately sounds like a fuse or a relay to me... maybe you should double check?

 

Ill double check. But what fuse or relay can control the whole electrical system?

 

Car doesnt even crank

 

if the headlights dont come on then it is deffintly nothing engine wise. I would look at the battery ground if you are positive it is not the battery. the best way to tell if the ground is bad is take your multimeter and hold your black lead on negitive post of battery and then red lead on ground cable. if you see any voltage at all the ground is bad. and if it was a pgmfi main relay then more often then not the dash lights would all light up but normally when the chk eng light goes off it wont or it wont come on at all.

 

wiggle your battery cables.
