-Removed all harness plugs..Cas, coil pack, injectors, tps, ICV, coolant temp.. everything that can be undone has been undone..
Still reading 4v at the ecu
After a bit of thinking.. I've come to the conclusion that if the ecu source is reading almost 12v with the ecu disconnected.. and 4 with just the bottom plug (ms) connected, It should limit my search to everything that is connected to the MS plug.. which is
-MAIN 28 +12V (almost 12v when not connected)
-MAIN 37 Fuel pump (Removed FP relay under dash)
-MAIN 20 Air temp (MAF unplugged)
-MAIN 23 OEM NB (Havent touched)
-MAIN 21 Coolant (Unplugged)
-MAIN 22 TPS (Unplugged)
-MAIN 26 5V Reference
-MAIN 24 Crank IN
Still getting same ****.. low voltage.
After hitting walls. I went back to the main fuse box... With all of them in, I started taking them out one by one and measuring volts again.
Whats odd is,
When I took out the "cooling fan" fuse, the ecu Volts went to zero.. which is not supposed to happen. Right?
I placed the "cooling fan" fuse back in and then took out the "FUEL INJ" fuse out. Thinking this fuse has ties into the main fuse, i was expecting to get a zero reading on the ecu.. Nope, got the same 4 volts... which is also strange.
So I'm thinking there is a strange short somewhere in the headlight/fan harness that's causing this crazy drain. I don't understand how this can be possible since I literally, have the fan and headlight relay harness completely undone and out of the car.
Any help would be appreciated.. even crazy talk is welcome.
