abs, brake light, turn signals, help!

Ok, I'll try not to miss anything. I have a 2000gmc sierra 1500 4x4. When I put it in gear and excellerate my abs and brake light comes on. If I have my headlights on both of my turn signals will come on and then fade out, then the abs light and brake light comes on. the only other problem that I have noticed is that every once in awhile my gas guage does not work properly it while stay on empty and then down the road it will jump up to were its supposed to be. Any Helpon this crazy problem will be appreciated. I can tell you I have checked all grounds.

the fuel guage problem is a fuel level sensor.

abs light could be a number of things, go get the computer scanned by a good repair shop or the dealer

other problems, sounds like you got a short somewhere...

Ive had it check on a snap on scanner, ever time it comes on it says lost communication with abs modular.

well then it sounds like you may need an abs module.....
