Question about 2002 Toyota Tacoma

1 Answer

Reversed Batter cables

I reversed battery cables when replacing the battery on a 2002 Tacoma. Now nothing happens when I turn the key (no lights or starter). Checked both fuse boxes (underhood and in dash), no blown fuses but don't know how to check relays. Did I cook the computer or could it be something more simple?

Check both fuse boxes again. You have a blown fuse somewhere and it most likely is one on the main fuses in the underhood fusebox.

Why am I having problems starting my Bravada. There is power, the started worksb, but when I turn the key nothing happens.All the dash board lights come on but no starter engagement?


do the dashboard lights go out when key turned to start? when you say nothing happens,is there a click? does the motor turn over,but not fire? is it an automatic,meaning is the gear inhibitor switch preventing starter from working?have you tried a jumper battery?putting a jumper lead from the battery earth to the engine ground helps sometimes,if earthing cables broken

Reversed the boost


you (at the least ) blew 1 or many fuses,
you do that and risk blowing up a fortune on electronics.
its not 60 Chev, that is so forgiving...

fuses: (ijm at alldata.com looking)
fuse 19, 80amps engine bay fuse box. bam?
are the head lights dead, they work all the time, even keys in pockets.
are they part of nothing.
then... that means... fuse 19 is bad.
open the fuse box in the engine bay see those.
they will all be dead, and 19 toast.
i just use a voltemeter to find which are blown.
starting there, then working to the cab box.
12v good
0v bad, key on

94 saturn will not start, new battery, completly dead


I would check the maxi fuses (big ones) in the underhood fuse box first. If you find one blown and replacement fixes the problem,be sure to get the alternator checked for proper operation,if the cables
were reversed the alt. often is "wounded".

Are there any main fuses on a 2001 plymouth neon


Have you checked the starter solenoid. Your battery + cable connects to this then + cable runs from it to your starter. You also have an ignition switch wire connected to this. Just follow your cable from the battery and it will lead you right to the part. Some times these will break inside or the contacts go bad inside and therefore you will not get power to start the engine, but you will have power to turn on lights or whatever other accessories.The part is about $15

My 2002 V6 4wd s10 pickup wont start. Checked battery its fine. checked alternator and it passed. it will not turn over. after inserting the key and turning the dash guages and lights will blink ans spasm...


Check your ignition switch (located on the steering column under the dash) If this is working, you will hear an electronic switch click when you turn the key on - if you do hear it then replace your starter
