Well about 3 days ago my meth stopped working. The pump seems to still be working, If I turn the key on the on position, I can hear the pump still whining. Even the light still comes on showing its working, but the meth still isnt going lower in the tank.... As if the pump isnt sucking or pumping the meth into the intercooler piping.

Anyone have a clue?

Thanks!
Dan

 

Sounds like the motor is ok but not the plungers. I think it might need to be rebuilt. Take the hose end off of the nozzle and see if it is pumping anything. Of course be safe about it

 

I posted this in another thread but maybe it would get answered here:
Quick question:
when I'm doing the test on the meth kit, with the check valve inline and the nozzle connected, the pump turns on and everything but it sounds like its pulsing rather than becoming progressive. The led stays solid green so I know there's no error. When I take the hose out of the nozzle (still going through the check valve) it starts slow and progressively builds up to hard.
Is it suppose to behave like that going through the nozzle?

 

Never mind, I called AEM and they said that it was normal behavior.
