Toyota Repair Problems? Ask a Mechanic for Answers ASAP
does the engine turn over but not fire up or does nothing happen when turning the key to start? When turning the key to on doe the lights on the dash turn on?
Thanks, ***** ***** like the battery is discharged or there is a bad connection at the battery, check the battery terminals connections and try to jump start it.
Ok, there is a 80Amp fuse in the fuse panel under the hood, does it have power to it? Is the fuse blown?
That's fine I will be here.
You're welcome, good night.
Thanks, ***** ***** alternator fuse supplies power to many other electrical circuits, using your voltmeter inspect all three of those fuses, they must have power to them and not be blown, you can open the plastic cover on each fuse to vheck.
Do both cables have 12 volts, if so are the fuses under the cover good?
Thanks, ***** ***** to verify that there is voltage at both of those large cable connections please.
Yes, both bolts should have voltage.
Good, earlier you mentioned that the engine dos nothing when the key is turned to start, that means the ignition switch is not getting power to the starter solenoid. When you replaced the thermostat did you disconnect the battery? Have you checked for any other fuses that may have blown both under the hood and on the inside fuse panel, check them with the meter and the key on.
It must be getting some feedback voltage from the relay or there is a bad ground, or the temp switch for the fan ontrol is disconnected or has an open circuit, the temp switch for the fan is located on the bottom of the radiator and has a two wire connector on it, if the connector is off the fan ill run with the key on all the time.
Yes, on this model and year the switch is located on the bottom of the radiator facing the engine and it has a two wire connector.
That's the temperature sender for the gauge on the dash.
let me see if I can get a picture to you that shows the location of the switch.
Thank, in that first picture, what happens if you disconnect the wire does the fan run with the key on?
Put a jumper wire to ground and see if the fan stops.
Sounds good, I just don't see the correlation between the fan problem and it not starting, have you checked the fuses under the hood and inside yet, I don't remember if I aksed about this before.
There are three fuses under the hood that have to have 12 volts without the key on, the 80A alternator, 30 A AM! and AM2, be sure these are not blown and have voltage to them.
Copy this link into your browser, it's a wiring manual diagram showing where all the relays are, there's also lots of other useful information.
