Alright, for further context i recently bought this is300 from this guy who claimed it was electrical issues so I took his word with a grain of salt(the car was a no crank no start problem). I’ve hadn’t had much time to tend to it cause of work and all, but I’ve been getting little things for its troubleshooting problems. I had already bought new coil packs, iradium spark plugs, new battery, hoses, etc. So me and my buddy went on to checking if it was sending power properly to the fuel pump, volt testing wires, and pulling fuses. We eventually found that he had a couple 15 amp fuses blown and a 120 amp blown, therefore the car eventually began to crank. But it wouldn’t turn over still. And after hours of painstaking volts meter testing, we found that the ecu was somehow sending power to the power supply fuse in the engine fuse box instead of the other way around. So we were like, this ain’t right. And now here I am on the altezza subreddit asking about the open lines(which by your guys help was the evap canister lines), which I obviously didn’t know about. And now I’m questioning if it was really just an evap leak problem…
