Lexus SC430 :: Car Wouldn't Start / Cranked Weakly When Stopped At Gas Station
Mar 15, 2016
2003 SC430 with ~140k miles. Friday night, stopped at a gas station and left the car running for about 15 minutes. Then stopped the engine and left the radio on for about 20 minutes. Then the car wouldn't start- cranked weakly, then began clicking. Jumped the car- took about five minutes before it would turn over again.
Then, after disconnecting the cables and running for only about a minute, it cranked strongly twice in the span of a minute. I found that strange, not believing that it had properly charged up that quickly. Drove to an auto parts store, asked them to check the battery and such. Battery said good, alternator said voltage regulator failure.
After about 10 minutes, went to drive off, not planning to stop until I got to my destination. The car wouldn't start again, same weak turning and then clicking (note- this after about a fifteen minute drive, as opposed to the first one minute of charging after which it started twice just fine!). So I was surprised that it wouldn't crank.
Then I drove it all weekend without a problem (5-6 stops and starts). Then Monday night after I parked it, I went back to check it and it didn't start (same weak turn, and then clicking). Tuesday morning, I tried twice and got weak turn & clicking, then it turned a little more strongly and started.
My guesses:
-don't think my battery is bad
-don't think my battery really was fully discharged and then suddenly recharged even though it has seemed that way, in such short time frames
-my alternator claims to be bad (voltage regulation)
-maybe I have some sort of loose connection on the backside of the battery? (the terminals look solid)
But I didn't shake or bump the car, or do anything for the cabling to be loose/bad Monday night, and then start Tuesday morning. But perhaps the very effort of trying to start the car is enough to shake a connection back together?
(I don't think this is at all related to my blower post- my fan seems to be kicking on quite frequently while I drive, still trying to sort that out).

Got in the car today, 2002 SC430, turned the key, car cranked and cranked but no start. I'm guessing I'm not getting fuel. How do I troubleshoot?

I had a problem recently with my '11 SE. It only did it once and hasn't done it since. I pushed the START button and the engine cranked over but it never started. I let it crank for about 5 seconds before I pushed the switch again to make it stop. The next time I pushed the START button the engine started.

I got this truck from my step father, drove it from mississippi to washington (state) with minor problems. It's been sitting in my driveway for the last 6 months and I probably drive it once a week. I loaned it to my sister-in-law and she drove it for a couple of days with no problems. She went out one morning to take it and it wouldn't start, just cranked it for a few minutes and gave up. To make a long story even longer, I though it was fuel so I checked the pump, changed the filter, drained some fuel thinking water might have gotten in, ... to no success. I then started looking at electrical. Spark was getting to at least one plug. Pulled the distributor cap and cleaned it all up, replaced all the plug wires, and then tried starting it with the same results. (Oh, by the way, no check engine light so I assume no codes).
This goes on for a couple of weeks as it's in the driveway and I only pop the hood when it's not raining (we live just outside of Seattle). The other day I have the hood open, my wife decides to check on me since she thinks I'm talking to God and is wondering why I would use that kind of language when address a diety. I ask her to jump in and crank it while I pull a plug wire to see if I'm getting spark....again. Low and behold, the truck starts right up. I jump in to see if it's throwing a code and nothing. The thing is running great. I did notice that there is a ticking coming from the engine compartment and I realize the plug wire is still disconnected so I turn it off (with much hesitation) connect the wire, go back inside to start it and the thing won't start. I'm a private pilot and they say, if you're flying along and you do something and the engine stops, undo what you just did. So, I go back out, unplug the spark plug wire, and the thing starts right up. So, I start thinking, try another plug wire. I reconnect it, try another, and it won't start. So, what I figure is that it will only run when the second to the front cylinder plug wire on the drivers side on the engine is disconnected.

If i have the radio volume up fairly high, it will keep cutting off for a few seconds then come back on. then cut off again etc....
I presume the amp is getting hot and causing this, am I right? And would I need another amp, or maybe there is a fan in the amp not working? Or am I not even close? Its pretty annoying when that good song comes on and it cuts out.
Its not the actual radio that cuts off, its the sound from the speakers.

Had an odd situation earlier tonight. The starter cranked normally but the engine wouldn't actually start. I let it go for 10 seconds and hit the button again to make it stop in order to protect the battery. A few seconds later, I tried and it fired right up without a hitch. The MIL never came on so no codes most likely.
Car has 17k on it. 2013 2.0

Last week, the keyfob I had with me stopped working (no wireless functions). The light still comes on but I couldn't lock or unlock anything. I started the car thinking it might be some sort of reset thing and then turned it off. The keyfob started working again. I thought it was just a glitch until today when it happened again.
However, this time, no amount of fussing fixed it. I retrieved the second wireless fob from the safe. It too doesn't work.
Either this is a failure or the security system thinks something is up and is out of sync or something. I really don't know.
.One is around 2.7 volts. The other is 3.0 volts.

My wifes 2002 explorer stopped taking fuel at the gas station. You can only put about 1/10 of a gallon in before it clicks off. I have already dropped the tank and checked the fill and vent tubes, and looked inside both of the charcoal canisters on top of the tank. Everything looks perfectly fine?

The navigation door stopped working about 6 months ago while the navigation screen still worked fine. Two weeks ago the door started to work as it should be, but today it stopped working again.
According to other threads people have published this could be from the door being off-track, a broken motor, and a blown fuse. Obviously none of these scenarios could be apply in our case.
Btw, I checked all fuses and could not find any problems with them.

Yesterday I noticed my nav screen stopped responding but partially. It'll let me press buttons on left side but not right side. Unfortunately the "I agree" is on right side so I can't even get passed that screen. I don't use the nav but I'd rather have the map showing then "Caution...."

At first the drivers side, side mirror would tilt as it should when backing up but when i got onto the street from my driveway wouldn't stop tilting up-words till it made a clicking noise that it wanted to keep tilting but couldn't. The only way to stop it was to adjust the side mirror manually and tilt it down and it would stop and stay at whatever i set it as. Now it just doesn't tilt at all.
What part numbers would i need to fix the problem? I drive a 2002 SC 430.

I have a 2002 SC430 and the seat memory buttons on both doors stopped working suddenly. No work done to the car, but I don't know what gives.

Got an interesting electrical issue on my 2004. I'm not sure if the issues are related but they happened at the same time. About a week ago the nav door stopped closing and the seat memory buttons stopped working. When you press the close button the nav screen moves back but the door never closes. The seat memory buttons on the door don't work either but the seat adjustment controls do work. When adjusting the seat position, as the seat moves moves, you hear beeping. It sounds like the same beep that you hear when memorizing a seat position. I checked and tested all the fuses they seem to be good.

A couple of weeks back out of the blue my Nav screen stopped tilting back and of course if it doesn't tilt back the door won't close. I did the Lexus Diagnosis on the Tilt and Close Switches and it turns out to be something in the 'Nav' unit. Of course Lexus doesn't sell parts for the Nav unit... just the whole thing.
Since that time I have spent way too much time on diagnosing it and I actually tried another used unit that has the same problem as mine. What I think that I have figured out is that the motors are ok but the control unit, a small circuit board within the nav unit has failed. The problem is that this unit has 2-3 IC chips on it and any way to repair this circuit board.
Any luck repairing these circuit board or am I stuck.... The I was able to retract the unit into the dash and the door opens and closes but it would be nice if it tilted as they had intended...

I have a 1997 Volvo 960 station wagon. It has been sitting in the driveway for 5 months. I went to drive it and it wouldn't start. We jumped it and it ran but wouldn't hold a charge. The battery was about 7 years old so we went and bought a new battery. We took the old battery out and replaced it and now it does nothing. It won't start and there is no sign of power to the car at all.

I am stationed in Europe at the moment and my wife has been driving my car.
She last drove it a week ago and when she got in to drive last night it would not start - Not even a "click". Interior lights worked, radio etc.
Could be the battery of course with not enough voltage threshold to even engage starter solenoid.
But I was looking for other things she could check before I come back in 3 weeks. I will deal with a battery replacement then if required.
She confirmed car is in "park".

Just disconnected battery to give a full charge because car sat for the winter and hood was propped open which killed the battery. Meanwhile I reconnected the battery and only the lights will come on. The car will not start with key in ignition. Don't know if there is a security issue or just what.
