    I have had a stalling issue off and on for quite some time now.

    Every once and a while when I startup in the morning I hear the engine spinning up for about 5-10 secs then it stalls out and I get the triangle of death. I remove the key and try again and it usually starts right up.

    The code is always "Engine did not start". Any ideas?

    The car must have stored diagnostic codes if the Triangle of Doom was on. What codes did you retrieve??

    Happened again last morning. It's about 10-19 degs here but that should not cause this and it has done it when it's hot out also.
    Anyone have any ideas?

    Yep. Really helpful diagnostic. Isn't it? As if you didn't know that it didn't start.

    I had the same thought.

    There is a technical service bulletin for 2001-2003 Prius that seems related. TSB EG011-03. If your 02 Prius has less than 80k miles, the ECM will be replaced for free. If the problem is more severe it may require fuel ank assembly and /or fuel pump relay replacement. Those are only waranteed for 36k miles.

    Plase let us know if this info helps resolve he problem, and any other details. Good Luck.

    I also own a 2002, with about 60k miles. I have had several check engine light issues (some with the red triangle of death), but they had always resolved themselves before I could get to the dealer. no pattern with weather conditions or driving patterns and when the check engine lights came on. However. on Jan 1 this year, I started my car- check engine lights came on, including the red triangle of death. I drove, it seemed ok, then the accelerator seemed to stop working (floored it, still didn't get above 15 mph). then the car stalled. competely. I was able to get to the side of the road,restarted the car- it seemed fine now, except all the check engine lights were still on. then after after being parked for a few hours, drove for about 10 min, all the check engine lighs went off. took the car to the dealership 3 days later, computer code was "P3139"-general error, not very helpful. they did a 60k maintenence and didn't find anything else- some carbon buildup, and a bit out of alignment but that's it. anyone else with similar experiences? anyoneknow how carbon buildup would have caused my car to stall? any bets as to if/when my car will stall again?
    I'm scared to drive my prius now! :(

    It's happened about 3 more times since my last post.
    I now have about 83k on the car, can I still bring it in under warranty? It's in New York, don't we go by Cali emmisions warranty?

    I purchased it about 1.5 yrs ago with 19k, I put a lot of miles on her!

    My 2003 is doing exactly this almost every morning (it is cold here, usually 35 degF or less). It starts great, runs 5-10 seconds or so, stalls. The triangle comes on. I have to wait a few seconds before I can restart it. Will Toyota replace the 2003 ecu for free? My car has 70k on it.

    So 2 here in this thread need to try to determine whether their shops will do the TSB EG011-03 fix. Yo can read and print a copy of that in the files section o fthe yahoo toyota_prius_sat1 group. Please let us know if that is the diagnosis and if it is curative.

    Carbon soot buildup on the throttle butterfly plate can eventually build up to such a level that it interferes with plate motion, or so I have read. Much more often there is a small visible amount, which doesn't affect operations. It is also quite easy to remove.

    There is way more to a check code than that. In the shop manual and various TSB's you usually find page after page of diagnostics and decision trees to follow.

    As an example: my 2000 GMC Sierra developed a rough cold idle in 2002. I had purchased the shop manuals with the truck, but since it was still under warranty I told the jerk dealer to find out what was wrong. Naturally they couldn't find anything.

    There were no trouble codes stored, but for the symptoms there were general fault tree diagnostics going on for 15 pages. Within 5 minutes the decision tree had me pointed to deposits in the IAC (Idle Air Control) passages and TB. I took the IAC motor off and sure enough, the passages were mostly plugged with a sludgy deposit.

    I cleaned the IAC and TB with the recommended 3M spray cleaner, put the IAC motor back on, went through the IAC Learn Procedure, and the truck idled smoothly again.

    Whether a code is stored or not, the decision tree and diagnostic procedures are really helpful to narrow down a problem.

    The dealer is looking at my 2003 tomorrow and I will report back. The service manager recognized the TSB right-away and stated he will replace the ecu if that is the problem.

    Just got back from leaving it with the Toyota Dealer for the weekend here is the info:

    Codes:
    P3191
    C1259
    P3101


    But here is where it gets interesting:
    Oil in intake manifold, need to remove manifold and clean oil out of it and reinstall. Cost: $219.25 + the $97.63 I just paid for diag.
    I think they are insane! I change my own oil with 3 quarts of Mobile 1, so it was never overfilled in the last 1.5 yrs I have owned it. I'm very frustrated with this car.

    I am just back from the dealer too. I had multiple codes and they are going to replace the ECM under warranty. They also said my Open Circuit Relay is bad, but I declined to replace it for $210. I am going to first see how the ecm replacement goes. It is backordered due to heavy demand and should be in by next week.

    Interesting, it seems that particular motor used in Prius has a problem with oil in the intake manifold. I can see if the car was always filled past Full by a dealer. Wonder if perhaps the previous servicing - before you bought the car - had that big an effect.

    Isn't there a TSB on this issue?

    I can report that even Prius engines that are not overfilled with oil will eventually get a little puddle under the accelerator butterfly. It is not too hard to clean. Also soot will accumulate on the butterfly and eventually could interfere with butterfly motion, and give you a non-start code. Again, not worth $220 to have cleaned if you are any sort of a DIY.

    If they say you need a new engine control module and your Prius has less than 80k miles, you get one free. If more odometer miles and you need to pay for it and are shopping around, make sure you get one with the last 2 digits of the part number is "54". A "51" was offered on ebay last time I looked but that will not be a guaranteed solution.

    I have noticed something...
    If when I get in the car I put the IGN to ON for about 5 secs then to run it does not stall.

    I'm going to get a can of TB cleaner and a K&N filter cleaner kit, can't hurt.

    I did get into an accident yesterday though ;(
    Was run off the road into a light pole, bumper and hood are toast.
