Hey guys I got an 2009 lexus is 250.
I was recently driving. Filled up gas. Did a utrun and my car sputtered and died. I tried to start it up, it cranked but wouldn't stay idle. I thought TB. Towed the car home and replaced the Tb. Realized the battery also wasn't charging and the alternator was also having bad response. I replaced both battery and alternator with brand new parts. Now the car has constant power with no power loss.

YET here is my biggest issue.
I get in I push the start, cluster does its thing and lights up. Navi. Etc.
Now when I push my foot on the brake the push start lights up green but when I press it. NO RESPONSE.
No tick, click, cluster movement or nothing.
Just stays green with no change like its not realizing the car is trying to start. My closet lexus dealer is 40 miles away. But I do have a Toyota dealer in town .
Im stuck and at a loss. Tomorrow morning I'm going to try all key fob and even engine flush by pushing both brake and acc ped at the same time to see if its bogged up from the cold weather hit. Other wise im lost.

 

The 250's have a much tighter limit on fuel pressure from the pump as it is the the pressure for the cold start injector. Low PSI or volume and you get the crank but no start issue. Starter fluid to the intake is the best test.

But now you have a new handful. Any codes? Start pulling fuses and recheck those battery connections. I bet you find it there. PS try jumping it...

 

I feel dumb. I woke up.the next morning (prob because I was mad drinking since I stripped bolts and more).

IT WAS IGN2 FUSE IN THE ENG BAY

 

^I was just about to say, since you replaced the battery/ALT to check your fuses and fusible link.

Sounds like you're all back to normal.

 

Yessir! Finally now im running good stuff to support the boom boom💥 I got in the trunk.
Ive always been scared of the fuseable link since I have never had to work with it or never had any issues. But during this I took a lot of time to actually look at it and research it 🙃 😅. Not so scary now
