Car trying to start itself

I have a 2001 Toyota Corolla.
It is a rebuilt wreck.

A month or so ago the car was trying to start itself.

It tried several times to start itself when I first head it I thought someone in the parking lot was having car trouble and couldn't get their car to start.
When I got closer.. I realized it was my car.. and the keys were in my pocket.

I quickly unlocked the doors and put the key in and turned the ignition on then off and it stopped.

The car smelt bad from the starter getting very hot.

I started the car up and drove home.

when I pulled in my drive and just as I was putting the car in park... the starter tried to engage again while the engine was still running.

Any ideas on what could have caused this? It hasn't done it since.

thanks in advance for the help

From your description - sounds like a short in the wiring in either the ignition switch, integration relay (sort of the car's central tie in point), or the starter relay and associated wiring. Depending on where the original damage was located, could be the insulation around the wire (wire jacket) has worn through and making contact with the chassis or wire could be crushed somewhere - either one would act intermittently, which would make it that much harder to track down.

Fortunately, it sounds like it is just engaging the starter - hence the starter cranking without the cylinders loading up with gas and actually firing up and running. That will help limit your search to the starter relay (in the relay box by the airbox, on the driver's side fender) and the wires that are hot for ignition switch position "start". If those check out, then you can expand the searching into the integration relay block and due a quick visual inspection of damaged wiring.

Sounds interesting. I don't think you have a problem though.. I think your car is just a transformer

it may have had a remote starter or alarm previously installed thats not totally uninstalled. look under the dash for non factory electronic modules and relays and wiring.
