I have a .10 amp draw coming from fuse 22 on my 2000 Jeep. Looked it up and it says this fuse is associated with the fuel pump relay and the powertrain control module

Any suggestions on how to figure out what’s causing it?

Btw, I pulled the fuel pump relay while fuse 22 was in and there was still the same .10 amp draw.

 

Try unplugging the control module and see if the draw goes away .

 

Just unplugged each connector to the PCU and the draw went away when I unplugged the far right connector.

 

You mite have a bad computer if you unplugged the auto shut down relay that powers up the computer .

 

many idea if I can test the computer to see if it’s ok before just replacing it?

 

So I followed the wires from that far right PCU connector and found that unplugging this made the .10 draw go away. Any idea what this connector is for?

 

No idea whatsoever, but thats what the FSM is for, free download it from cruiser54.com, go to the electrical chapter, and see what pinout is specified, check the circuit diagrams etc

It is known that the internal mosfets in the PCM that ground the injectors and ignition can become short circuit (but you would expect a misfire), however the PCM also grounds other things like the voltage regulator etc
