#32 of 54 Engine starts then shuts down by spiak Jan 21, 2009 (5:57 pm)
I have a 2002 Prius with 161,000 miles on it. It has been a great car. A problem I am having is when it is cold (below 32 degrees F) When I start the car in the morning it starts right up will run for about 10 to 15 seconds then shuts off and all warning lights come on. Then when I try to re-start the engine will not turn on for three more attempts but it will always start on the fourth try. Always! Then the car runs fine. The warning lights will remain on until the next day and then will go off, or I can turn the engine on and off four times and the warning lights go out always on the fourth restart. Any info would be greatly appreciated Replies to this message: spiak (Mar 02, 2009 1:59 pm)

They cleaned it and everything is fine. Posting this in case someone has the same problem. They say it should be cleaned every 15000 miles or once a year. Apparently I clean mine every 162,000 miles.
#34 of 54 Lost of power while diving by Wool948 Mar 13, 2009 (6:50 am)
I was driving my 2008 Prius (24500 miles on the odometer) on the hwy at 60 mph, the low fuel indicator light starts flashing, since i was only 12 miles to my destination and the vehicle averages 44 t0 48 mpg, no worry, I figured there is perhaps 2.5 to 3 gls. left in the tank, I can go another 100 miles If was in the middle of nowhere. All of a sudden the engine shuts off, I pulled over thinking that I ran out of gas and called AAA for help. But after a while, I was able to start the engine, I could not drive foward but I was able to back up. The vehicle was taken to the dealer on a flatbed. They claim that the car ran out of gas, that my problem had nothing to do with the perfomance of the engine, it's not a warranty work. The same inccident occured 2 weeks earlier on a full tank of gas, then I pulled over for a few seconds and continue my trip, at the time i thought nothing of it, just a freak thing. Has anyone experienced that problem? Your input will be greatly appreciated Replies to this message: cathie2 (Mar 21, 2009 10:35 am) dono0034 (Mar 22, 2009 6:09 am) pf_flyer (Mar 22, 2009 6:16 am) Wool948 (Mar 22, 2009 10:37 am) jonnied (Nov 02, 2009 2:50 pm)

Every fall I clean it and no problems for the rest of the year.   Sticky Prius Throttle Plate   Bob Wilson Replies to this message: stevegold (Mar 14, 2009 9:12 pm) typesix (Mar 18, 2009 6:48 am) Wool948 (Mar 15, 2009 8:33 am)

Replying to: bwilson4web (Mar 14, 2009 4:30 pm) Is this a common problem on the 2004-2009 Prius? I've never heard of this before. Replies to this message: typesix (Mar 18, 2009 6:48 am)

#38 of 54 Car WON"T START by chazz5 Mar 17, 2009 (6:55 pm)
My Prius has 65,000 miles on it and it is a 2007. I was waiting for my wife and I had the dome ( interior) lights on and the radio on. I went to press the start button and the car would not start. No dash lights would light up. My key fob would not lock or un-lock the doors I had to do that manually. My interior lights and brake lights would work, but no dash lights and the car just would not start.What could the issue be anyone know? Prior to starting my car, my 2 year old was near the gas, break peddles. Could I have over looked the emergency break being pushed in or could this be another issue all together Replies to this message: stevegold (Mar 17, 2009 7:33 pm) chazz5 (Mar 18, 2009 5:11 am) chazz5 (Mar 18, 2009 10:33 am) kdhspyder (May 23, 2009 9:48 am) stevegold (Sep 01, 2009 7:32 pm) jonnied (Nov 04, 2009 1:15 pm) jonnied (Nov 04, 2009 4:26 pm)

Replying to: chazz5 (Mar 17, 2009 6:55 pm) This has happened to my 2004 twice. The fix is to jump the small battery located below the trunk floor FROM the special terminals located under the hood. All it needs is enough juice to fire up the computer. After the first time, I fixed the front cigarette lighter to be on all the time and bought a small 12VDC booster battery from Autosport. Plugging that in will start the car if you remember to keep the booster charged. Replies to this message: chazz5 (Mar 18, 2009 5:11 am)

Replying to: stevegold (Mar 17, 2009 7:33 pm) Thanks, but what do you mean by having the front cigarette lighter to be on all the time I don't understand.

Replying to: stevegold (Mar 14, 2009 9:12 pm) Common problem on many cars, not just Prius. It's carbon buildup on the throttle valve.
