I got all 4 (bank 1,2, A, B) camshaft sensor codes showing and a no crank situation. All of the sensors would not fail at once soooo. I assume one of these things happened. Main timing chain jumped or major cam phaser issue which can happen on the earlier versions of this engine. BUT I want to check to see if it's a blown fuse or relay. I can't find anything out there about what fuses or relay these may be controlled by on this so I can look at them before I tow this to a real mechanic. Any other non death knell things this could be? My wife said there were no symptoms before hand and she just couldnt restart it 4 minutes after turning it off. No engine rattle before hand. If I have to take out the engine for a fix I'll probably look at a new vehicle instead of repair.
Odds are it's what the timing chain. It's either broke or stretch too much. Another sienna is a generally worth money. If you can find a used engine and have it installed that would do that and sell it or keep it rather than just trash it now cuz you won't get much for a vehicle that doesn't run
Any other non death knell things this could be?
wiring issue like frayed wires, corroded grounds, etc.
Depends what the codes are
