1997 Cummins 12v 20 amp fuel pump fuse parasitic draw

[@BrianHenry83]

Do you start the truck with the toggle off and then when the truck is running you switch the toggle on?

[@4g63tpowered]

@BrianHenry83 when I opened the door to get in I would just flip the switch. You leave it off and start it truck isn't much a fan every light will be on in the dash.

​@4g63tpowered thanks bud, does your batteries still drain with the fuse pulled? I'm still have that issue. My batteries are only a couple years old.

Did you figure out where that fuse goes ???

[@4g63tpowered]

@@EastMenloPark1650 it's the pcm power

[@EastMenloPark1650]

I’m having the same problem with the same fuse. Help me please

[@4g63tpowered]

Get a new pcm or wire a toggle switch to the inside of your truck. I put mine in the fuse panel by the driver door. It's solved for now until I get a PCM.

[@4g63tpowered]

By wire a toggle switch I mean 2 bladed female ends on either side of where fuse goes route the wire install the switch. Pretty easy deal

[@EastMenloPark1650]

When I replace the fuse I get a dog whistle noise coming from the ecm

[@4g63tpowered]

Your pcm might be totally gone then buddy
