Question about 1990 Toyota 4Runner

1 Answer

EFI underhood relay

I have a 1990 toyota 4runner with a 3.0liter v6. My relay for the EFI seems to be getting very hot,and then gets so hot that it shuts the engine down. I have checked the relay behind the glovebox and it seems to be okay. There is no blink codes coming up and the check engine light is not on. Also there are no fuses blowing or circuit breakers tripping. Does anyone have any ideas or input, any help would be appreciated. Thanx dave w

I would replace the relay that gets hot, and make VERY SURE that the relay pins fit real tight in the female receivers for the relay. A *** slight *** amount of clearance at the connection will arc & def heat up the relay. Once relays get really, really hot, it, at times, they may no longer be reliable.

1990 4Runner v6/aut, 4x4. Turns over but won't start. Seems like it's not getting fuel


Spray some either into the intake while someone is cranking the engine. If it starts temporary and then quits, it is definitely a fuel problem. Check your fuel pump.

Location of idle adjustment screw on v6 with efi


There is no idle adjustment screw, as idle is controlled by the car's computer through the idle air control valve (IAC). This is possibly sticky, and needs a clean. There is a throttle stop screw on the engine, but that is a different thing.

What is the EFI fuse on a toyota camry


It supplies the EFI Main relay, which in turn powers the fuel pump, ignition switch, and starter relay. In addition it powers the ECM computer, so that if you wish to clear a trouble code from there, you pull the EFI fuse for 30 sec. See here p177

91 4runner not running on 1,3,&#4


Seems like you replaced everything on the ignition but the cap. Sounds like a good place to look to me.
Look for burn marks around contacts.

Efi fuse blown after engine start


I think gas is not getting to your fuel rail.

Could be the fuel pump. To access it you will have to remove you rear seat and take off an oval shaped plate. There you can remove it and replace the pump.

I have a 1990 toyota pickup DLX ext cab V6 5-speed


If it seems to run well otherwise, you might have a partially obstructed catalytic convertor. Usually if this is the problem, the engine will also bog down even if you try to rev it up when it is in neutral.
