Picked up a 2018 3.5 eco from copart with flooded engine (I know, I know..) I've swapped engine, trans, bcm and under hood fuse box from donor 2020. I bought a used ecu from ebay. The truck has some power, odometer, radio, locks, lights but when I turn the key nothing happens. I know the truck won't start until I get key programed to new ecu and bcm, but shouldnt the dash light up when i turn the key on? I tried hooking up forscan but it wont connect cause its acting like it cant connect. Tia

 

Best of luck with the project. If the engine was water damaged, it`s a good bet that almost every other part of the electrical system maybe excepting the dome light has damage. Just curious, what made you want a flood damaged vehicle?


PS: With a join date of 2013 with only one post, that has to be some kind of record. Right?

 

I guess I'm gluten for punishment. The water damage didn't seem that bad inside. The carpet was wet but didn't seem like seats got wet.
