something grounding out my AC,NEED HELP

[kdbvulcan]

Hey guys,I just put and air dog fuel system on my 03 dodge,and the pump on it seems to run quite a bit longer than my 01 dodge did,I lost a little power,but it starts fine,I am just confused,I had a dodge dealer check it out and the one mechanic said something is grounding out my compressor,anyways after I put the air dog in the check engine light come on,and my AC quit blowing cold air,do you think something is wrong with my air dog pump,they perty near checked all they can check out on my AC,seems everything is fine,its just something keeps kicking off my compressor,when you turn the key on you can hear it try to kick on but then it kicks back off,I NEED SOME ADVICE, THANKS

The same thing happened to me last week, but it also killed my truck like popping the clutch on a gas vehicle. I believe the fix is to to move the TST ground to inside the cab onto the dash chassis per the TST website FAQ's when a FASS etc type pusher pump is added (I added the Walbro). Do you get the P0647 "AC relay high" code?



I haven't got around to moving the ground yet, but the AC hasn't quit since the last time.

Yes I get the same code reading,something is not grounded right
