Default Troubleshooting (2008 Lexus is250) car wont start

Hey everyone. Ive seen many post regarding this issue, car not starting. Not sure what it can be. Is it my camshaft positioning sensor or my fuel pressure sensor. Please see below to see the lights on my dashboard.

thank you,

I don't see a MIL on so I would say your battery is probably bad. Get it load tested, and report back. If you have and OBDII scanner with ABS capabilities. You could scan the car for a code. Also if you have an DMM turn the ignition off, and check voltage on the battery should be 12.66 volts DC.

The battery light will only come on if your having charging problems. When did you purchase the new battery? Sounds like a weak battery to me.

Make sure the cables are on tight.

If you jump start it, and runs. Take it to the auto parts store to check the battery. Then go from there. Yep it's frustrating.

Scratch that if it starts just pull the battery and take it to the auto parts store. If you shut it down and won't crank again most likely the battery.

No. So what happen was, Friday after work turned my car on. Drove from Yorba Linda to Long Beach. Parked my car. It sat there the remainder of friday, all day saturday and sunday. Monday morning when it was time to go to work i steped on my brake, pushed my engine starter and almost turned on but not quite there. Took my battery to the shop told me it was a bad battery. Got a new one but still nothing. So yesterday i tried tightening it up as it was as tight, left the negative kinda lose. Cranked it again and nothing. The only thing it was doing before was that my rpm were kinda low. Around 600rpm while in drive.

I dont see the gear position light on your cluster so it must be a bad fuel pressure sensor behind your fuel rail. Replace them and it should start.

Not sure if you're in a cold climate but in Toronto the exact same thing happened to mine it wouldn't turn over after being left for 3-4 days in the cold with all those same dash lights. Its just the battery, a boost instantly started the car and then you'd want to drive for a bit to let the battery charge

Trying to start the car in the beginning caused it to throw a bunch of crankshaft engine codes and check vsc message. The car seemed to run perfectly fine after the boost so I cleared the codes and it hasn't returned which is good. If the car starts and runs normally after the boost you should clear the codes or else the dash lights and check vsc will stay
