Prius (2001-03) :: 2002 - Engine Won't Start?

I own a used 2002 Prius and have only been driving it for about two months. In the last week it has given me some trouble on start up. I turn the key, but the engine will not start. Unlike some of the other comments I've seen here, I'm not getting any warning messages when my car won't start. I turn the key and the dash lights either come on half lit or not at all, the computer screen doesn't light at all when this happens. If I hold the key in the start position for a few (up to twenty seconds) it will eventually turn over and start, but that seems to be draining the big battery and doesn't seem like the best way to start the car. This happens about 2 out of every three times I go to start the car and it doesn't seem to matter how long I've had it parked - could be an hour or overnight. Conversely, it could be sitting for a day and a half and start without issue. All in all, there seems to be no obvious condition that would cause this, and I was curious to know what I should troubleshoot and in what order. As with many people these days, money is scarce and I don't have the money or time to keep it in the shop for a week for diagnostics, especially when it might be something I can easily fix on my own.

Prius (2001-03) :: Does The Immobilizer Only Check The Key At Engine Start?

I have a 2001 Prius and my wife has a 2001 Highlander. I only have 1 master key remaining for the Prius, and both cars use the same transponder type. I had a plain (metal, no transponder) copy made for the Prius, and it turns all the locks just fine. I also followed the master key programming steps with the metal non-transponder key in the ignition, but holding the Highlander key in close proximity to the ignition. It worked! If I have the highlander key on the keychain next to the metal spare Prius key, the Prius will start. The Highlander key is now a 'superkey,' it will start the Highlander, and it will also pacify the Prius immobilizer.

But this is not 100%; if it doesn't sit right on the keychain, I sometimes have to hold the Highlander key a little closer to the ignition to get it to recognize. I

Prius (Gen 1) :: 2001 Engine Will Not Start - Fuel Gauge Flashing

I have a 2001 prius. It has around 105k miles on it. i bought it when it had 86k. I've had 0 issues with the car other than replacing the 12v battery in the trunk and its always run like a champ. Today though, i went to start the car and it started up as normal. I left the keys in the car for a second to get out and talk to my wife.

When i happened to look in through the window though i saw that the cars fuel gauge was all of a sudden flashing. The entire bar. (when i started it originally it had 5 bars of fuel) I got back in the car to investigate and noticed that the engine had turned off. All the power was still on with no triangle of death/turtle or anything else. only the flashing fuel gauge was on. I tried restarting it multiple times to no avail. The power will come on fine, and the dash will appear as normal. The motor just will not start.

I thought it might be fuel so i went and added a gallon just in case, but still no luck. Problem usually have lights that come on or the triangle of death.

Prius (2001-03) :: Check Engine Light Came On - Vibration On Start Up

This has been a very good car for us. We've had it since '03 with 30k. Problems have been minimal, till now. The 'check engine' light came on several months ago, and we were unable to afford the repairs. We used it as a 65 miles per day commuter car, mostly at highway speeds. The mileage has dropped off abruptly from the long-term 42 mpg down all the way to 24. There is a nasty vibration on startup. It lasts for maybe 30 seconds and then calms down. We are now at a place where we can do the repairs.

Prius (2001-03) :: Subtle Knocking Noise For Few Seconds When Start The Engine

Recently, when I start the engine (cold or even warm starts) I hear a subtle knocking noise that doesn't last too long but a few seconds. I figured that maybe it's because our area may still be using winter mix gasoline... but I'm not sure. Also, there's a rattle underneath the car when the engine switches into generating electricity with MG1.

This only happens after a start-up procedure (cold or warm). It stops when I push the gas pedal down a little bit (while still in park) then it goes into charging again, and by that time, it's stopped. I figured it may be a heat shield on the exhaust. It sounds more up in the front.

Also, when I start the car, the engine starts smoothly but then 1-2 seconds later goes into spinning MG1 which makes the car kinda sound like "vrrrrrrr---VRRRRRRRRrrrrrrrrrr...." .

Prius (Gen 1) :: 2001 Engine Won't Start - Fuel Gauge Blinking Continuously On Dashboard

So right now I'm not able to start my Toyota's engine. I checked multiple screens and found several weird symptoms that I never saw before.

1. When attempting to turn the engine on, the square light that appear over the selected D, N, P positions etc does not appear at all and the 'Ready' light never appears. When putting the car into the Parked mode the square does not appear over the 'P' on the dashboard or any of the other modes and Ready light does not display.
2 . On the dashboard the fuel gauge is blinking continuously. Its showing full bars while blinking even though I have about 3 cars worth of gas in the car.
3. On the computer screen when I go to the Energy menu (The screen that shows the Battery life and the Motor and Engine working together) The battery life is showing as completely empty. But the battery should be working considering the computer screen even turns on. Radio also works.
4. The OBD II scanner does not get a reading. The scanner powers on when plugged into the car, but a "Linking Error" occurs when attempting to read any error codes.
5. On the same computer screen where the Energy menu is displayed, the Temperature gauge is showing an "E" instead of an actual temperature.
6. On the outside of the car I hear a very faint sound that I don't recognize. It could be nothing but its not a sound I ever heard before.

Also NO WARNING LIGHTS are appearing on the dashboard. Which makes sense considering the car engine is not turned on to show anything. I don't know where this issue is coming from?

Prius (2001-03) :: Dreaded Triangle / Gas Engine Refuses To Start Then Restarts After 5 Attempts

I bought a 2002 abt a year ago, and every 1000 miles I get the red triangle and the gas engine refuses to start. Initially it starts, then shuts down after a few seconds. Weird thing is, after the 5th or 6th attempt, the car starts normally and off I go. When I turn the key to "on" the check light goes on. This has never happened while I drive, only after the car has been driven and parked.

GMC - Sierra :: 2001 - Won't Start When The Engine Is Hot

I have a 2001 GMC Sierra with a starting problem: When you've driven it long enough for the engine to reach about 210 degrees, if you stop the truck it won't start back up until the engine has cooled down to about 200. It only does this when it's over 80 degrees outside, though.

Santa FE SM (2001-06) :: 2003 4WD V6 2.7L Engine Won't Start

We recently changed the timing belt & serpentine belt & new alternator. Drove great for 2 days. Then car would stall out when idling, had rough idle. We replaced the Crankshaft position sensor (got one from the dealer) & the electrical connector. The engine cranks but won't start. The only code we're getting is P0335. We've checked all the fuses. Fuel pump starts when turning on the key. We've been a week without a car and trying to come up with something.

Elantra XD (2001-06) :: Engine Cranks But Won't Start When Hot

I just purchased an '01 Elantra a few days ago. The car starts and runs when the engine is cool, although it hesitates during acceleration, and when it's warm outside it bounces between 1000 and 2000 RPM in neutral and park. The last day or so it's been chilly and the idle has been steady, but low (500 RPM). Once the engine warms up, however, if you shut it off for a few minutes and try to restart it cranks but won't start until the engine cools off.

The previous owner replaced the fuel pump, cam sensor, crank sensor, spark plugs and wires, and I replaced the intake gasket and the idle air control valve, all with no effect. I can hear the fuel pump when I key it on, and I've checked for spark at each of the plugs, and even pulled the injectors and cranked it a few times to be sure that they were firing. Everything seems to be in working order.

Prius (2001-03) :: No Start If The Temperature Is Below 28 Deg

My 2002 Prius wont start if the temperature is below 28deg. The dealer doesn't seem to have any idea why. They replaced the battery but it didn't make any difference.

Prius (2001-03) :: Won't Start / Getting CEL But No Triangle?

My 2001 won't start. When the key is turned, the system starts up and the hybrid system initializes, there are 3 clicks in the dash, and the check engine light stays on, without the engine even turning over. I had a mechanic look at it cursorily and he said it looks like the hybrid system is fine, the signal to start the engine isn't resulting in the engine starting. He said it was probably the starter or a fuse to the starter, but the gen 1 Prius doesn't have a starter, so I don't know that I can trust his diagnosis.

The 12v battery is brand new (3 months old) and is an aftermarket deep cycle battery. Also, it has been very cold here. The triangle of death doesn't appear, so I am hoping that it isn't something in the hybrid system. It did this off and on before it stopped starting at all. I was also getting the turtle intermittently when it was giving me occasional problems. Turning the car off and on a couple times usually made this go away. The car has 154k on it. I am thinking it might be the ignition starter switch, but I'm not sure.

Prius (2001-03) :: Crank But Won't Start

Car is a 2001 Toyota Prius. Car had a dead 12V battery but I had a portable jump pack I always use to start the car no problem. I had the car in the shop to do some body repairs and I'm guessing the mechanic might have reversed jump the car as the car was working just fine (by jumping) before I took it in to the body shop.

- When I jump the car, the HV battery will crank the motor for about a second, the engine tries to start but stutters out.
- When I try to jump again after 10 seconds, the HV battery will crank the motor but now just a split second and the engine barely cranks and doesn't start.
- When I try to jump again after 10 more seconds, the HV battery will NOT crank the motor and nothing turns.

The car dash screen shows that the HV battery is at about 25%. There is no engine codes.

What I've done:

- Replaced the main 100A fuse by the 12V battery
- Disconnected and reconnected the main HV battery flip switch

I'm down to my last option as the Toyota dealership was useless and wanted to charge for a new 12V battery and diagnostics before looking at why the engine won't crank.

Prius (Gen 1) :: Warning Icon And Check Engine Light Popped Up Upon Engine Start-up

Recently there has been a series of problems popping up with the Prius. Its a 2003 model year.

- About four nights ago the warning icon and check engine light (picture below) popped up upon engine start-up and i noticed a weird idle. It seemed to idle rough. After about 20 seconds of idling the engine would shut off. After about 10 minutes and 6 or 7 attempts to restart the engine the warning lights disappeared and idle seemed to be restored.

- The afternoon after that the same warning icon and check engine light popped up along with the rough idle. After about 10 minutes and 6 or 7 attempts to restart the engine the warning lights disappeared and idle seemed to be restored.

- After this incident it seems like the vehicle is getting bad gas mileage. The picture below shows me getting an average of 25mpg. I was driving very conservatively. Driving the same way i usually do, i usually get 45-50mpg. The vehicle seems to be charging the battery more than usual.

Elantra XD (2001-06) :: 2003 Won't Start After Engine Heats Up

So my temporary solution has been taking the gas cap off for 10-15 seconds, I suppose so that the tank can release any excess pressure. Then the car starts fine. This has worked pretty much every time. If I don't do this I could end up waiting for about 15 minutes before the car starts up again. They must be related. Is there anyway that the tank pressure isn't being vented properly?

I've replaced the thermostat, the ect sensor, the crank sensor, the fuel assembly, I've cleaned the injectors and replaced the fuel tank pressure sensor.

Buick - Lesabre :: 2001 - Engine Week At Start Up

I have a 2001 Buick LeSabre (Limited), with 101,000 miles. It runs great and a very reliable car except:

After going for some driving in town during a warm day (60 F or above) doing business, the engine gets warm but within normal temperature range, and after making a stop to get groceries for eample, I have to be very careful when starting the car again. If I let the starter go for more than a quarter tourn (crank), the engine gets week and acts like it is flooded with gas, just like when we had carburators in old car and it dies after a few shakings.

So I have to wait for 15 minutes at least before I restart the engine but doing so I have to be really careful again not to let the starter crank for more than a quarter turn. However, this problem does not happen during cold weather days (say below 40 degrees F). What is going on with my car?

Prius (2001-03) :: No Start Up Because Fuel Pump Won't Run

What sensors etc. besides the mass air flow sensor have to be working in order for the fuel pump to run? I get no fuel from the fuel pump even though the engine is cranking. There must be other relays, fuses, or sensors I can check even though all fuses I can see are ok. How can I check the EFI relay to tell if it is ok?
