Asked by Jan 03, 2014 at 08:47 PM about the 2001 Lexus IS 300 Sedan RWD

Question type: Maintenance & Repair

I drove my lexus to work this morning and everything was fine, after work I tried to start
my car and it would not start.   This has never happened before, Ive checked fuses, oil,
and belt. The oil was really low but that wouldnt keep the car from starting. I had a carmd
check and it comes up yellow light but no code.  I was thinking it was fuel injector or
plugs, hoping it is something simple. Does anyone have any suggestions or has had this
happen before to them

Actually the motor oil being very low will prevent it from starting. A Lexus has that feature to prevent people that DON'T KEEP CHECK OF THE OIL from blowing the engine. That's why it didn't throw a code. Is it all that much trouble to pop the hood once a week and pull the dipstick?

I was wondering if u got the car to start. I had the same similar problem. Mine is an 02 is300 n it just didnt wana start one day n was not getting power to the relay. I took and tried a few things like the gas cut off sequence in the manual also did the ecu reset and still didnt start. I took and sprayed starter fluid in the intake n it started so that told me its a fuel problem so I replaced the fuel pump and fuel pressure regulator and it started right up. This is something lexus wanted to charge me 850 for. Hope this helps

No I havent got it started, how do you do the fuel cut off sequence and how do you reset the ecu

The car has a fuel cut off system. For u to reset it the manual says to turn the key to the acc setting n let it sit for a few seconds then turn key off then turn car on. As for the ecu reset disconnect the negative off the battery n let sit for like 5to10 min and reconnect. Ppl also used the ecu fuse under the hood in the fuse box in front of the battery but I found the battery thing lil easier to understand. Also have u checked to see if ur security light shuts off after u insert ur key? If it doesnt then u have a prob with ur immobilizer n prob need to reprogram it

Ive reset it by taking off negative terminal but still nothing, I've ordered a fuel pump because I've had a diagnosis done on it and the mechanic said thats what he thought it was. I will post if it was fuel pump or not, I have to wait a few days for shipping. How do I get to the fuel pump, isn't it under the back seat?

If u do the fuel pump u should get the fuel pressure regulator also bc they r both together... n yes the pump is under the back seat here is a like that might help u with pulling it out. It honestly took me less than an hr n its the first time ive done it. http://my.is/forums/f221/diy- walbro-255-fuel-pump-install-pics- alot-409785/

It was fuel pump, I replaced the fuel pump and the fuel pressure regulator in about 30 mins and I have never done it before. It was pretty easy, pull up on bottom back seat firmly and pull seat out, unscrew 3 nuts for cover, squeeze wiring harness to remove

Undo a clip from fuel line and pull off, unscrew about 8 screws and then pull out fuel filter at an angle and replace parts. It is very easy. Thanks jdm4life you were right

Check your altinat or maybe crankshaft position sensors

So you think my altinator can be why my dash board does not lit up nor my power in my radio is coming on...but everything else works n the car it sounds as if it wants to start but just doesn't fully turns over

Yes it was the fuel pump. Little expensive at the dealer so i ordered it at a parts store. Also replaced the fuel regulator due to it being in the gas tank connected to the pump

Its just started a leak because it never use to lose oil at all but ive filled the oil reset the battery and still wont start. Ive also checked the fuel pump relay, relay is good but not getting power to the relay. A mechanic was saying it has something to do with starter wiring or the starter. I also have an interlock, do you think the interlock could cause the problem if there is something messed up with it?

My problem was the fuel pump, simple to fix, it took me about 30 mins to change and I have never done it on my car before. But minnieminh I'm unsure really it could be a number of things like MAF sensor, bad fuel injectors, bad spark plugs, bad fuel, your not really giving enough information

A 2004 IS 300 will start but none of the other electrical functions -work? Can't get it out of the garage. Can't shift. No buttons work...other than starting the car Problem started after changed battery because reversed the two battery cables for a moment...I presume that wasn't good. Replacing fuses did not help. Anyone with similar problems...and hopefully solution?

I have an IS350C and twice after work the car would not stay running. It temperature outside was in the mid- to high-90's. The car would turn over, then immediately shut off. A friend suggested trying to put the car in gear before it shut down. This worked and I was able to drive to the dealership to have it checked. When I went back the next day, they found nothing wrong and there were no error codes. My question... is there something that prevents the car from starting in extreme heat?

I have solve my car problem (Lexus ES 300 1996). I don't know how other Lexus are built, but my Lexus did not have a Battery Hold Down on the car and that is why I had problems, at times, with starting the car. Sometimes, it could be that you have a very small battery that is loose (which causes the electronic flow to not properly function) or simply you have no hold down, which without it, when driving the car (into bumps ESPECIALLY), the battery will move which will cause it to not properly generate power when it starts. I had NO PROBLEMS (thank the Cow Gods, LOL) after putting a hold down on my car.

Not answer-- Problem: My 01' es 300 will not start unless I punch the gas (my guy told me to) or refuses to idle at correct rpm after starting unless I keep giving it gas until it warms up. Did not start this until the weather changed to lower temps for Fall. She runs like a champ and starts the rest of the day. Any incite?
