why arent my tail lights working?

Question

when I hit the brakes it pops the fuse, the left turn signal pops the fuse and when I hit the right turn signal it flashes all the right tail lights (including reverse lights) I cant find a short to ground anywhere. you can turn the the left blinker on shortly before the fuse pops and it blinks all my gauge lights it even makes the injectors pulse fuel! weird

I cant find a short anywhere I replaced all the bulbs and it still does it, I just put a new motor in it (350) and right after this started to occur

the truck is a 91 s10

Answer 1

you probably have a pinched wire somewhere. look under the hood that's where you were working on it when the problem developed. good luck

Answer 2

OK the brake lights are powered by a switch on the brake pedal. You may have pinched some wires. Sounds like it is in the left wires. go hunt them down.
OR you can replace them by running a new loom to the rear lights.
Big project, good luck.

Answer 3

you have a ground problem and i would start with the brakes, but it also could be in the steering wheel when u put the new motor in. also check your bulbs, some can only go in one way , but with wear u can put in backwards. good luck

Answer 4

All main power goes thru the turn signel switch in the center of the steering colium shaft. If you have this switch checked you will find your problem.Best of luck.

Answer 5

unplug all your rear light wires keep adding wires til the fuse blows unless it still blows then goto uncle reds idea
