ok so I dont know what to do? I change the head on my car today put it all back together & now it wont start. as if the battery is dead but its not everything in the car turns on. but the CEL doesnt ever come on same with the battery light or the oil light. once you try to turn it over the oil & CEL come on for a sec. but its really dim. and I have put a charger on it & nothing changed. what do you think it could be?

 

I had a similar issue this morning with my LS. Although I had battery power, it wasan't starting or turning over..and I wasan't throwing any cel's...

it cranked fine when the sun finally came out and defrosted it...maybe too cold.

 

problem solved it was bad ground connections thanks
