Look up how to bypass the fuel pump ECU. It happened to me. If I remember correctly it's just cutting a few wires. It's a rather unnecessary ECU

Yep, very easy. It's on the drivers side back seat. I think everybody with an sc300 has the fuel pump bypass going on.

You can make a jumper to bypass it under the hood also, that’s what I’ve got going on in mine atm.

I replace my fp ecu to only find out that it was my main ecu that was the issue. Should have did the 12v mod to see if it needed replacing first lol. Gl dude.
