A/T or M/T ?????? Auto or STICK>? shift.????????
for sure , all elect, problems always check all fuses first in both boxes. (endless posts that.)
and endless 2, clean the battery lugs and check battery voltage
12.6vdc rested is a good battery.
it can be many things not just those.
do you want to guess, or tests... ill skip the former.
NO CRANK, is the problem.
1: so does Jumper cable starters work<
yes, battery is bad or discharged, (bad battery or charge system failure)
no, the jumper test failed,
so what to do next, (i use meters)
A: I hot wire the solenoid, big lug to dinky lug. all keys in pocket....!@!!!
it cranks great
that means the starter is good, and the key line is dead.
it dont crank, bad starter. (or seized engine?) hand turn engine, ok, its ok.
ok the key line is bad.
so why is it, until you tell what transmission in car ?????
1: M/T clutch switch bad/
2: A/T the PRNDL switch is bad.
see tricks at end, the magic.
my posts assume
1: no aftermarket hacks to the starting systems (no remote start bs)
2: no aftermarket alarms. hacked in. removed many .....
3: other hacks gone wild , even audio installers with out a clue.
