How to fix low idle
Here is the most common cause of surges and stalls low idle speed, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
1991 toyota truck relay clicks no starts
check battery cable connections. Dirty/corroded wil cause that condition. Headlights bright? try starter with headlights on.If clicks and they dim slightly,have a friend TAP the starter with the key in the START position. USE a long length of re bar or metal rod. Tap on the starter motor,like a pool cue. If the starter cranks on the first "tap",the starter should be replaced. There are brushes inside the electric starter motor and when they get burned/worn,a slight tap jars the starter motor brushes just enough to make good contact.
Where is the horn relay under the engine
The horn is in front of the grill and radiator on the drivers side it is a black disk.
The relay is int the engine compartment on the drivers side in relay/fuse-box. The name "Horn" should be on the fuse-box lid to identify what relay is needed.
Question: Is your horn only sounding at certain steering wheel positions? If so the problem the brass contact plunger in back of the steering wheel is worn out. You can buy a kit with the ring and plunger to fix that.
Why do accessories stay on with key off and drain my battery
My first guess is the ignition switch being faulty.
1st unplug the switch module and see if that turns the accessory lights off.
Test the ignition switch (on the switch side):
A. White , White Red wire is 12V constant
B. Blue/Red wire is accessories.
If there is continuity between these two wires when the ignition switch is OFF then replace it. $55.00 for the module.
Where is the obd port
If your car is equipped with obd, look under the dashboard for a plug receiver, usually on the driver side.
How do you change a voltage regulator on 91 toyota pick up
That is too much to say you had three bad alternators.
You have a short or high resistance load being drawn somewhere in your circuits and the standard alternator will work for a while then die.
Option 1: Purchase a higher amperage alternator that might be able to handle the higher load.
Option 2: Find the short and fix it. Easier said than done. Did you recently install a sound system? Maybe an Amplifier? or electric windows?
-Best of luck.
1991 toyota pickup 6 cyl.manual tranny 4x4 coming
Brake light and battery light coming on mean the Alternator may have died on you. Check the alternator, it may be bad. The popping out of cruise may have happened because it did not have enough current flow, due to alternator failure.
