2007 Lexus IS350 hesitant to start

Recommended Posts

Hey team, 

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!

      Hi,
      Has anyone programmed the HomeLink from a 2007 IS250 Lexus with a 2018 model LiftMaster Premium series 8355W (belt driven) garage opener? or know if they're compatible?  I just got the LiftMaster 8355W garage opener 5 days ago and been unable to program it with HomeLink buttons in the 2007 IS250.  According to the HomeLink site, they provide instructions to program with LiftMaster for the 2007 IS150 so I assume this means it's compatible (?). Cleared all HomeLink programming and tried all the steps to program opener following instructions from Owner's Manual, HomeLink web site, various tips given online..etc. The only step that doesn't seem to match with the instructions is that when I'm trying to sync remote with the desired HomeLink button...I get the slow blinks while I'm holding both buttons but it never gets to fast blinking, just does the slow blink until the light just stops blinking. I went ahead and continued with all the remaining steps including the learn button on the opener and going back to car to press the HomeLink button. Tried all this multiple times and different ways but still no luck. Never had issues programming it previously. Wondering if anyone has successfully programming 2017 or 2018 LiftMaster with 2007 Lexus, or maybe it's no longer compatible with the latest garage openers.  
      Any info/help would be appreciated.

      New to this Lexus ES 350 Club: I always said I'd own a Lexus by the time I turned 60 (just as my Dad said he would own a Lincoln by the time he turned 60 - and he did). 2 weeks ago (and 5 months before my 60th bd), I did it. I now own a Deep Sea Blue Mica 2015 ES 350 with 44k miles in excellent shape. Prior to this, I drove a Toyota Avalon Limited, and I thought the ride could not be any more quiet or more smooth. I was wrong. The Lexus is far and away more solid, quiet, comfortable and smooth. I made a great choice for under $24k.

      Hello! My name is Jake and I have an 04 RX330 with 230,000 miles on it. Not certain on the history of it but I have gotten it with no heat and an overheating problem(EDIT: previous owners said it has overheated on them). I immediately knocked out the easy stuff, checked coolant levels, verified fans were working. So I end up doing serious work that it needed: waterpump, timing belt, power steering pump, upper/lower intake gaskets, thermostat(THM 117-$11.32 at napa), valve cover gaskets, spark plugs. I end up finding smoke swirling out of a crack in the radiator while the car was idling for an hour during a fuel injector decarbonizing process. I end up replacing the radiator as well as the fan motors with the relay because the fans wouldn't turn on. I ended up using a power probe straight to the old fan motors and only fan #2 worked. I end up putting it all together-bled all of the air out of the cooling system with an airlift evacuation tool-and this thing is still overheating! Today I pulled it in and put the scantool on it-temp reads 244 degrees, so it's up there. I take a laser thermometer gun and the passenger-side (or upper hose) of the radiator read 183 degrees give or take and the part of the intake that the sensor screws into was around the same. So I thought it's only a $20 sensor, and replaced it-also considering it had a previous P0117 code(engine coolant temperature circuit low input). I know when the DTC is aiming at the input part of a circuit, it's talking about something with the sensor. I thought this would do it, BUT the car still overheats via gauge. Good news was I had heat, so I'd blast it when it starts climbing up and it'd slowly go down. I'm really stumped now, because I know the heater core acts as a mini radiator, but it doesn't make sense that the heatercore cools the engine down but not the fans and radiator being fully functional. The upper heater hose is piping hot with pressure but the lower hose is room temperature with pressure, I verified by squeezing the hoses. Is the thermostat defective? I installed it with the wobbler pin positioned at the top via installation instructions. I feel like I might run a compression test tomorrow to check the head gaskets, but I feel like I'm missing another sensor or something-I'm a freshman in college so anyone with experience I'd greatly appreciate it!
