same problem with my 2003 es300... drove today then parked. came back and something turns like an electric motor on the tranny side® (its FWD) but no motor response. in hind site i could swear it sounded a little high pitch during start up the last week or so... Please help...

these problems suck, I just bought a 92 SC400 150k miles and inherited the same problems check to see if your check engine light comes on in the run position or while your cranking if it is not find out why your ECU is not getting power thats why Im getting no spark, there are wierd fail safes on these ecu's I found one of my camshaft postion sensors to be faulty but still doesnt explain the lack of a check engine light at start up, need to find out what is cutting spark and fuel, I can jump the FPR and IGR relays and get it to start but it wont stay on, Im suspecting unless this car has some wierd problem where if the ecu doesnt get a signal it shuts it down Ill keep you updated I will be working on it until its fixed. there is alot of talk about the ecus crapping out between 150k and 200k miles, find out if it has voltage if it does chances are there is a fault in the ECU mine is most likely a ground since it randomly does it to me
