My car wont start. I checked the battery and was only showing around 5 volts. I charged it overnight and it was still showing 5 volts. I took out the battery and had it tested, it was bad. I put in a new battery and the car still won't start. The battery light and service engine light are on and the dash lights won't go out when the battery is connected. With all that the car won't even turn over. I could use some help if you have any ideas! Thanks.
For the past year or so, if I leave the car alone for a few days, regardless of temperature it has trouble starting. When I go to start it it will crank for a while but only fully start by giving it gas. When it starts an large plume of smoke along with fuel smell fills the air. Check engine light is not on.
I removed the air intake plastic stuff and put the key in the on position and a rock on the gas pedal. I removed the plate at the top of the throttle body and sprayed and cleaned out the 9 or so mini holes and the 2 larger holes. With my limited car knowledge I assumed this area to be the air intake bypass when the pictured valve is closed. I cleaned out throttle body as much as I could from the front without removing it. I had good results with this. The car started and maintained higher rpms than before. I thought it was a great success.
I then left it alone for 10 days and it wouldn't start.
What should I check next?
Do oxygen sensors have a role is starting or just running?
Does the MAF sensor have a role in starting if the throttle plate valve is closed during starting? (I didn't mess with the MAF sensor) Air filter is about a year old, lightly dirty, not filthy.
Help... I like this car, but I don't like the Lexus service bill. Thanks.
My wife's 2001 ES300 has had a slow battery drain that results in a low battery charge and inability for the car to start after several days of not being driven. I first charged the battery to 12.7 volts with a battery charger, I checked the alternator and found charging at 14. 4 volts and took the battery to Pep Boys to conduct a load test and battery condition after 1.5 hour charge. Battery checked out in good condition. I then proceeded to finding what was causing the battery drain. Using a multimeter set on "amps" I removed the ground connector from the battery and hooked one multimeter lead to the battery and the other lead to the disconnected battery ground cable connector. After 3-5 min. with the ground strap disconnected, I took a reading of the battery drain. The multimeter showed a 150 ma current drain. At that point I started pulling fuses to see which would stop the drain. When I pulled the 10a ECU-B fuse the drain immediately dropped to 20ma. The question I have is what devices/circuits receive power through the ECU-B fuse? Second, what further steps can I take to determine what device/circuit fed from this fuse are drawing current with the key off and the car sitting idle?
So I have a 2006 Lexus ES330 with 83,000 miles. It's been a great car so far. I have noticed the acceleration slip that most people talk about but I'm ok with that. I just had a new battery put in three days ago under warranty because my battery of less than two years completely died. I also had my inspection done at the same time and passed. According to Firestone they tested my alternator and it was fine. So now three days later I am driving and my car goes nuts like it's having a power surge, I can tell the accelerator isn't engaging, the dash lights (brake, ABS, check engine and a faint battery light) come on and my air starts blowing super high, then low and does this about 3 times before I shut it off. I parked the car and after about 1 min all the dash lights go off but the check engine light. I go to auto zone and have them run a diagnostic and it shows my vehicle speed sensor caused the check engine light to come on. Well that doesn't explain the power surge and my speedometer (which is usually the first to go if the sensor is bad) is working fine. Any ideas???
I brought a 2007 Lexus is350 5 months ago and about 3 weeks ago it started making a really strange noise when I started it, then it would go away. A week ago I went to turn it on and it didn't start. It was trying but wouldn't spark. Took it to a mechanic who said it was a fuel pump and replaced it but since I've had it back it's been really hesitant to start. Sometimes it starts fine others it's trying and trying then last second it sparks. Could it still be the fuel pump? He also ran a diagnostic on it and everything showed up as normal. Appreciate any help!
