#1 of 54 Toyota Prius-Fails to Start by katiehard Jun 17, 2007 (9:00 pm)
My Sister has a 2003 Toyota Prius and when she goes to start the engine will roll over, but it won't start. My brother says it's the fuel pump, or something. Does anyone have any idea what it could be? And if so, how much will it cost, estimated with parts and labor? Thank you sooo much!

#3 of 54 Toytoa Prius warning message - car won't start? by acj Jun 19, 2006 (8:03 am)
I am posting this on behalf of my Aunt, who actually has the car but it not at all computer literate so I told her I'd try to help.... She has a 2006 Prius with about 6,000 miles on it and has started getting an intermittent error type message that says (as best as she can remember) "Trans axle will not charge batteries while in neutral" and the car will not start. The dealer is unable to replicate the error and suggests that it is "driver error"? Has anyone had this message or problem?

#4 of 54 It happened to me once by texvegas Jun 19, 2006 (8:22 am)
While cleaning the inside windshield I apparently hit the shift stick and when I tried to start the car, I got the same message. I turned off the power, got out of the car, got back in and it started as always. I think you get this message if you try to start the car in neutral.
#5 of 54 patience is required by john1701a Jun 19, 2006 (8:27 am)
Pressing the POWER button before the brake is fully depressed will cause a lock up where only neutral is available... hence seeing that message.   Simply waiting until your foot has finished moving will prevent the problem.   That little bit of patience makes a huge difference, and it is so subtle that most people don't even realize they have jumped the gun... until their awareness is heightened by having done that.   JOHN
#6 of 54 and another thing... by acj Jun 19, 2006 (8:33 am)
forgot to mention that she phoned Toyota to talk about this problem and they told her that the car was unsafe to drive until this was fixed? Based on what you guys have said so far it doesn't sound unsafe to me......

Replying to: evanr1 (Oct 11, 2006 8:50 am) Evanr1, pardon the questions, but how exactly did the Prius initially lock up? Also, how is that the "starter" battery is known to be dead but the main battery is known to be good? Generally, if the small 12-volt "starter" battery is dead, then you should get no dash lights and no interior lights. The 12-volt battery is used to "bootup" the computers, which in turn connects the high-voltage main battery to the car (it is isolated via relays when the car is off).   It sounds like you ran the 12-volt battery down by accident, either by leaving a door open or an interior light. You should be able to "jump-start" the car to get it working again. The instructions on how to do so are in the manual. You do not have to crawl back into the back of the car to get at the actual 12-volt battery. There is a 12-volt positive terminal inside the main fuse box of the engine compartment specifically for this purpose. Positive goes to this post, negative goes to any unpainted engine part. The manual should indicate a prefered negative connection point to use for jumpstarting. After you make the connections, you should be able to hit the Start button to reboot the computers and hopefully get things working again.   I'm curious as to how the keyless key managed to stay stuck in it's slot, and how the dash lights stayed on while the rest of the car appeared to be dead.
