Know idea. I paid to have a dianostic run but they could find anything wrong. Have know idea what circuit or part is making it not run
Re: 4 runner wont stay running
first thing you should check then would be your main EFI relay. it should have four wires that go to it. Black and green goes to the fuse and when it's turned on the white with red should send the power from that fuse to the diagnostic connector that is marked B+ (pin #12)
check it with a dvom. Hook the meter up to battery ground and the pin #12. watch to see what the meter reads when you turn the key on and then what it does after the engine starts. See it the power turns off and then the engine dies or does the engine die and the power on the pin stay powered up.
that will check your EFI relay.
