01 Gmc Sierra Pulsating

PROBLEM 1

 

I GOT AN 01 GMC SIERRA 4X4 THAT WHEN THE BRAKES ARE APPLIED THE WHOLE FRONT OF THE TRUCK VIBRATES AS YOU SLOW DOWN THE CONSISTENCY OF THE VIBRATIONS SLOWS WITH THE TRUCK. I HAVE REPLACED ROTORS AND PADS ON THE FRONT OF THE TRUCK. I ALSO CLEANED UP THE SLIDERS AND OTHER MOVING PARTS WHILE I HAD IT APART. STILL NOTHING HAS CHANGED.

 

 

PROBLEM 2

 

TWICE WHEN I'VE GOTTEN IN MY TRUCK TO START IT IT STARTS UP AND DIES 2 TO 3 TIMES THEN LOSES ALL POWER. IF I TAKE THE GEAR SHIFT AND RUN IT THROUGH THE GEARS THE POWER WILL COME BACK AND THE TRUCK STARTS AND RUNS FINE. WHAT I MEAN BY LOSING ALL POWER I HAVE TO RESET ALL STATIONS AND THE CLOCK ON MY RADIO IT'S LIKE THE BATTERY GOES DEAD.

 

 

THANKS FOR YOUR HELP IN ADVANCE

Don't know about P1, but P2 might be a loose battery cable (which you've probably already checked) or it might be a loose ground cable on the motor from the negative of the battery. That's where I'd start - especially if it's not throwing codes.
