Prius (2001-03) :: Stumbles When Turned Left - CEL Came On - Ignition System Won't Working?
Dec 24, 2013
I noticed yesterday that my 2001 was stumbling when turning left. Later in the day, the CEL came on, and I retrieved a P0301 code. In both cases, I was driving around town, not cold but not fully warmed up, engine temp around 40-70 C.
I haven't done any further investigation, other than trying some different driving experiments. I've been able to recreate the problem several times starting out with a left turn when the car briefly runs on three cylinders. Going straight or turning right is fine.
Question: which cylinder is #1? My intent is to check the plugs and leads first, but since it's cold outside I'd like to focus my attention as much as possible on the problem area. I thought at first it might be fuel related because of the turning behavior, but on reflection, it feels more like an ignition issue.

My 2004 Elantra is having electrical problems. I left the keys in the ignition one night, and now systems within the car do not work. The car no longer responds to remote controls (lock/unlock). The lights in the cabin do not work. The digital clock and radio displays are blank. The gauges are also reading incorrectly when I start the car (all of them move up and freeze for a few seconds at 4000 RPMs, 70 mph, Hot Engine, then come back down to correct readings).
The car starts fine, and I have checked all fuses. I tried letting the car run to charge the battery, and also tried a jump start from another car to recharge the battery.
Remember, this all started when I left the keys in the ignition over night

Started this winter as a misfire on random cylinders. I replaced all apart plugs and verified the gap. Replaced all the coils. Still occurred during the cold months. Once it warmed up it went away for a short while. The only codes present at the time were random misfire codes. Took it to a shop and they told me the injector was bad on cyl 1. Today I replaced the injectors with a matched set of 4 matched flow Denzo remand. Ran it on the TIS tech tool and was given a barrage of codes. I can unplug #1 coil and it will smooth out and stall within 90 seconds. Engine runs rough. Intake was just done as well. From Toyota TIS

c1259 - ABS error code meaning problem with regenerative braking. Probably caused by me forcing the car to recharge the HV while misfiring. HV battery was getting dangerously low from sitting for the last 6 months.

01 Elantra, once warmed up to running temp starts to run like a pig & wont idle, has new plugs/leads.
Funny thing is there is no engine check light, in fact it doesn't even come on for the 6 seconds when the ignition is first turned on at all.
Secondly I have OBD2/ELM327 with scanpro but it doesn't connect to the ECU.
We put it into a shop & they claim they were able to connect to ecu but gave no codes which I find a bit strange.

I have a 2004 Elantra GT, and for the past year it sometimes makes no attempt to start when the ignition key is turned. All the dashboard lights, radio, bells and whistles are fine, but once the key is turned to start nothing happens. There are no clicks or anything. Some dashboard lights stay on and I can hear the initial whirring under the hood from the electrical system.
I've replaced the battery, ignition wires, and plugs. This will happen very erratically. Then all of a sudden it will fire up like nothing was wrong. This is always over a several minute time span of trying and retrying to start. I took it to a mechanic but we can never replicate the problem while there.

I have a 2001 BMW 330i. The car has been a dream since the beggining but lately issues have risen to the surface. Today, when I turned off the ignition all the dashboard lights remained on. The keys in hand, lights off, nothing else on, but the dashboard was lit up light a christmas party. I recently recharged my battery, a problem, I think, caused by the cold temperatures. Other than that I have not noticed anything wrong ..

2001 Ford Taurus 3.0 DOHC. Starting Problem. When the door is opened the interior lights come on, door dings, etc. As soon as the ignition is turned everything goes black all power is lost. Disconnect battery cable and reconnect, the open door again and the interior lights come on, door dings, insert key and turn, everything goes black, the car does not start. This cycle repeats over and over again every time the battery is disconnected and reconnected. I have replaced the battery, ignition switch. The starter was replaced last year. Why does power blackout, and car not start when the key is turned?

Ok, so I'm working on a 2004 Hyundai Santa Fe, 93,000 miles. The vehicle runs great! So great that you cant get it to stop running!! The problem is intermittent and generally happens after the vehicle has been running for at least 3 minutes. I turn the key off and she keeps on running (not dieseling, but running at 340-450 rpms!) I have already removed the aftermarket remote start that was installed on the vehicle thinking that was the problem, it was not. Then I went to the ignition switch and unplugged that, also to no avail! I plugged my scan tool in and can communicate with the computer and view pids while the key is on. When I turn the key off, I should loose communication. When everything acting normal and the car actually shuts off with the key, I loose communication with the computer upon turning the key off. When I turn the key off and the veh. keeps running, I do NOT loose communication with the pcm. The only way to shut the car off is to step on the gas pedal. Otherwise it'll run at 400 or so RPM for an hour or so!!

My wife's 2001 Gran Prix has a problem with the ignition switch, or related to the ignition switch. Intermittently (more frequently in warm weather or when the car's warm) the ignition switch can't be turned back to the 'off' position all the way, meaning the key can't be removed from the switch. We've heard from several mechanics that there are a couple problems that can cause this, and in fact had the ignition switch replaced which did not solve the problem. I understand there is a connection to the transmission or gear shift lever that may also be part of this problem in some way. There can only be so many solenoids, switches, connections, etc, related to this, I'd like to fix the problem and avoid spending money unnecessarily.

I have a 2004 Hyundai Sante Fe 2.4L that keeps blowing the ECU fuse under the hood when the ignition is turned on. We have replace the fuel pump and the inertia switch. I have tested the relay, ignition failure sensor, both coils and O2 sensor wiring.

This weekend I stopped my car, put it in park and turned it off (or so I thought). I was in a hurry so I didn't really look at the dash, I just left. When I returned to my car a few minutes later, it was still on. The dash was all lit up, the running lights were on, the stereo was searching for my phone, etc.
I put the key back in, turned it on and turned it to off position and the car shut off.
I'm going to speak to the mechanic when I take it in for an oil change next week, but it's a little worrisome.

I noticed one of the adjustments for the Carista 3.0 is to Open vents to outside air when ignition is turned off. The factory default was set to *Yes*. I changed it to No because I was thinking when it's really warm outside (I live in warmer part of silicon valley) and you crank up the A/C and then park outdoors, opening the vents to the outside will warm the car faster. Don't know whether my assumption is correct or not?

Early senility or perhaps just a busy mind has led me to turn off the ignition key before shifting from drive back to park. This is obviously not natural for the car but it did not seem to do any harm. I am wondering however if it can be damaged by this?

The prius alpha i own has this rattling noise when the steering is turned left or right. A local mechanic advised to lubricate the opening on the top of shocks, I couldn't find the Lube spray by Liquor Moli or 3M liquid Grease. I tried a spray by WD-40 Specialist Water Resistant Silicone Lubricant, but no result .
I have this Grease (attached pic).(desperate measure). Shall I apply this? And how?

Installed some tein h techs few weeks ago but I started noticing a "popping" when the wheel is turned left or right at low speeds. Driving down the road and hitting bumps is fine,, but at low speeds left or right I hear a weird "pop" or click coming from the front shocks.

Long story short, I had run down the HV battery in my 2001 Prius. It turned out to be a faulty wire to the ignition system of the ICE. While diagnosing, I let the HV battery drain, at least I think I did (Please see image of my HV battery specs). My question is, How can I charge the HV battery? I read Öut of Juice" but do not have the charger. My question is can I make one?

I have a 2007 Prius with about 80K miles. In the past year or so, I have noticed that the audio system temporarily malfunctions particularly when the car is left outside in the sun for some time. For example, I just returned from an out-of-town business trip where the car was left in an airport parking lot for 5 days. After starting the car and beginning my drive home, I noticed that the radio worked fine but I could not engaged the CD/Aux function.
Similarly, the power button did not function properly; I could not turn the radio off without turning off the ignition. This has happened several times before when the car was left all day in a parking lot out in the sun. After the car is driven for a while, the audio function returns to normal.

I just bought a 03 Prius at a car auction. the key was in it and it started just fine so I drove it 150 miles home with no problems. Parked it and tried to remove the key but it will only turn counter-clockwise to ACC, no further, so I can't pull it out. I took the steering wheel cover off, pulled the ignition out and once it's out the key rolls all the way over just fine but when I put it back in it still does the same thing. I've lubed it--makes no difference. If the battery cable is disconnected it will roll all the way over and come out but once I put power back to it it stops at ACC again.

I have a 2001 Accent, manual transmission 1.5L. The lady who had it before me overfilled it and stuffed the charcoal canister. She had this replaced, but when I bought it she reported that it still had a fuel issue immediately after refueling. She said it would stall and run rough and hesitate.
After I bought it I took it to refuel and confirmed the problem. I had read that the ECU may be trying to draw fuel through following refueling, but the new canister might be messing something up. She used to only drive it commuting distance in a city, so I took it for a long drive. Running at steady cruising state for a prolonged period seemed like a good idea, to allow any ECU learning. This partially fixed the problem! Now, most of the time, I can leave a fuel stop without a 20km drama before the car settles down, although the problem hasn't entirely gone away and it still does play up sometimes.
There's a more pressing problem which may or may not be related, however. When launching from idle, the engine goes through this 2-5 second hesitation of no power at all. If I rev up before letting the clutch out it's ok, but there's a certain minimum revs needed to avoid the problem. This is killing my clutch, and if I get it wrong it sometimes leaves me in the middle of a busy junction with no power for an uncomfortable period! During the hesitation, I've found the best way to force it is to put clutch back in and go full throttle. After 1 second or so the revs come back. The problem is much worse when the air conditioning is on.
So the clues are:
1. the previous charcoal canister issue
2. the full throttle thing might indicate something with the TPS
3. the worsening of the problem with the a/c on
Things I've tried so far...
1. prolonged cruising; seemed to improve things after refueling but overall fueling issues not fixed.
2. disconnected the battery -ve and applied brake light circuit to drain ECU capacitor, then left for any power-hold relays etc. then reconnected battery and took it for a normal drive for 30 minutes or so. No effect.
...and things I've yet to try (all gleaned from searching this forum)
1. checking / replacing plugs and HT leads
2. checking / replacing o2 sensor
3. checking the TPS plug connections. Checking the sensor itself sounds expensive - would it involve more than standard OBD?
4. checking vac hoses, in particular the hose which draws from the cannister
5. checking alternator (not sure how); the worsening of the problem with the a/c on could indicate low power getting to injectors etc? (bit of a wild guess)
In a former life I was a diesel engine calibration engineer, so I know the tricks which manufacturers can put into ECUs. What I don't know is the tricks specific to this car.

2003 camry 2.4 ... This is what is happening, cooling fans will not come on except when the AC is turned on and they will stop working when the AC is turned off, otherwise the car will over heat.
This is what I have done...Replaced the fans (because the radiator fan was bad, after hooking them up directly to the battery). I checked all the grounds, including the one under the intake, checked the fuses, checked relays using 12vots to the relay and used a ohm meter to see if it made contact when activated, on the three fan relays. Replaced and tested the new radiator sensor using a pot of water on the cooking stove with a cooking temperature gauge and ohm meter. It tested ok.
Unplug the radiator sensor while the car is running, the fans will come on, but go off as soon as it is plug back in, even when the motor is over heating. Also replaced the thermostat.
What can I do next, before I burn the motor up trying to fix it? Motor just started running rough. Just now pulled up a code of the number three cylinder miss firing
