Good evening all, Just recently purchased my 06 gs300 thinking it might be a simple fix but u guessed it it wasn't. Little back story, previous owner states he changed the fuel pump took it for a test deive afterwards all good. Got up next day to go use the car and he stated it wouldnt start not sure if the dash illuminated then or not. He said he left it tried again later and absolutely nothing was happening. ( this may be true pr not idk) I'm jus taking his word for it. Now I purchased it I bought a new battery for vehicle and also replaced battery for key fob first few simple steps to try. Still nothing on dash no lights nothing lighting up on ign push button. No lights horn doesn't lock nor unlock car with fob. I checked all fuses even the fuse bar near battery all good. I dug in a bit and said let me try jumping the ignition relay and boom the dash lit like a xmas tree. I said let me jump the starter relay as well to see if it turns over ( and not the engine being locked up) it swung and bubble like it was gonna start. But still nothing by itself. I scanned it while I jumped the ignition relay and i got the B2799 code. And a few other trans code but I didn't pay to much mind to those as I wanted to get car going ( unless those have something to do with it as well idk). Cars stuck in my drive way I'm totally lost and jus want to get this figured out. Down to one vehicle again and need tl get this up and going as one vehicle doesn't work for the family. Got someone that checked it out said ignition push button checks out good he said key is bad I took kt to the locksmith today to get another key, locksmith said key checks out fine nothing is wrong with it. So I'm lost once again as to wat it could be. Any and all help would be greatly appreciated. Thanx in advance.
