in need of some one with some experience with 1uzfe’s or old ls400’s in particular. im having issues with mine and could really use some one to bounce ideas off of. the car suddenly wont start, i wasnt having any issues prior to this. the only thing that happened was the cars alarm went off twice over night, and now the car wont start. the only thing that i can think of is that the car put it self in some kind of anti theft mode. the car has also locked me out of the trunk completley. i already checked the battery and it fine. the starter isnt even spinning thats why i think it might be an anti theft thing. ---

It sounds to me like a security system function for sure. Why did the alarm go off in the first place? Was it hit from the outside or was a motion sensor triggered inside? ---

Do you have the keyless entry? When you lock it, press the lock button twice. The 2nd lock press should disable the interior motion sensors if I remember correctly. So if those sensors are going crazy at least you can rule them out. ---

I like where this thread is headed… no mufflers? sliding? Burnouts? Awesome. I assume it has keyless entry/remote with that alarm setup? Sounds like the transponder might be dead. > [@91MR2](#): > > Nice engine… Really useful response! Way to bump up that post count! ---
