got it from like look something is going on here take
it up there I get stuck in the lot car won’t turn on the
guy comes out to look at it pops the hood tells me
to turn the key while he’s pulling some wire and
bam the damn car immediately starts he says it’s a
bad ground wire they replaced it it’s doing the same
damn thing again my boyfriend got under my hood
and grabbed the same wire last night cuz we were
stuck at Walmart for a hour and bam car turns right
