Hey all,
I have a 95 Lexus ES300 (my fiances parents old car) that had quit on them and would not start as they tell me or it would continue to run even with the key out. It has sat for many years. I made an attempt to troubleshoot the problem so they can clear out their garage. They had pulled the battery out so i go to put it in and when I started to connect the battery terminals as soon as it was connected the car tried to turn over, with the key in my pocket. Im assuming obviously there is an electrical issue but i dont know where to begin ignition, comes to mind 1st, that or the starter any help would be greatly appreciated!!
Staying in the future in-laws good graces would be a + !
Thanks
Jesse

I have changed the ignition switch and still the same problem is apparent. With or with out the key in the vehicle trys to start. Checked the battery for voltage and it was dead i hooked up some jumper cables and they got real damn hot real quick. My next thought in this dillema the starter itself which i ruled out because it trys to turn over as soon as the battery terminals are connected but speaking with a friend he thinks the coil on the starter is shorted any thoughts all?

Does the starter just keep cranking with a battery hooked up? If so the solenoid is on top of it and you won't like where it's all located if like another I just observed it's a 12 rated job whole top of engine needs come off as the motor is hidden inside! Not sure every model did that and forget now which one it was.
Any other history, remote starter or any hacked wiring?

Yes, with the battery hooked up the vehicle just keeps cranking.
I did get a visual on the starter just by googling what the spare part looks
like and where it is available. I have not found a visual diagram as of yet or a haynes manual on it.
No remote start or hacked wiring that i have observed.
Its a 95 Lexus ES300
Dang..... I appreciate your insight Tom any further would be appreciated
I will do my best.

This solenoid on top of starter motor is triggered by a small wire to energize solenoid for a much larger gauge wire to run the starter which is enabled by the smaller gauge wire and when meshed with (I'll just call it flywheel gear/ring gear) would in turn crank the engine.
Solenoid is just an electromagnet plunger and could be stuck after the years but is spring loaded to be off and small starter gear should back off is the typical style. I don't have wire colors for you to check to see if it's staying "triggered" and if a hidden starter which it might be awful job to check right at it. Generally this is not a problem set up but sitting for a very long time open the book of maybe problems. I'm pretty sure if gear from starter is staying engaged with the larger right gear the power will stay on to keep it running. Wish this was easier to get at as just a tap on solenoid might snap it to retract and right now bet it's stuck engaged. This type starter and solenoid on top the solenoid makes the connection to empower full battery power to starter itself AND throws the gear out to engage it.
Basic Haynes manual I doubt is going to be comprehensive on wiring.
The time and conditions while sitting make this a challenge.
IDK for the moment but how long did it sit without being run? What were the conditions of the garage it was in?
More - do you want this car for yourself to use or just get it out of there?
