Question about 2003 Lexus Gs 300

1 Answer

I have a 2003 Lexus GS 300. It will not turnover, and when I hook up jumper cables to the battery, my horn goes off. My hazards go on, and stay solid, but nothing else is happening to the car.  My horn immediately stops when I take the jumper cables off of the other car.  Is it the battery, my alarm system, other?

Jumper cables were used incorrectly on my gs300. The battery was replaced and now the horn blows and the lights flash. Now the car will not start. I was told to replace the main fuze. Which one is it...

You need to lock the car up. And then open it with the key and then put the key in the ignition and turn it on. This should reset the security.

Most cars have a emergency fuel shut off in the trunk that shuts down fuel pump when hit in the rear end. Try to push that . Or poor some fuel into injectors then see if it will turn over.

Ive got a lexus gs300 with a flat battry ive conected jump leads to a van left it running for 5mins the lexus is trying to turn over but will not start

When a battery goes completely dead. it needs replaced. you can jump it but you will have to leave the jumpers on for about 30 minutes to get the battery to hold enough charge to start. revvingthe other engine doesn't help, it only puts out so much voltage.

Electronic dash you will need the power on. Pull your car up, hook up the jumper cables and then turn on the switch in his car. You don't have to start it , just power it up.

03 gs 300 the hood will not lock

Either your cable has seized in the open position, or the lever it pulls on has. Have someone sit in the car and gently pull and release the hood release while you spray a penetrating fluid on the cable and the latch it activates. Then try to move the hook portion of the latch by hand.
