Re Tapping Whacking the starter solenoid works because
1) It helps actuate the starter solenoid plunger that is not getting enough power from flawed wiring of starter solenoid on Mid 86-88 22RE's,
2) It helps actuate the starter solenoid plunger that is not getting enough power from poor wiring (LOONG) on Early-86 and earlier 22REs without starter solenoid. (Fixed by adding starter relay like KidV's solution, or Hotshot relay).
3) It helps actuate the starter solenoid plunger that is not getting enough power from LOONG wiring on auto trans 22RE where neutral safety switch contacts may be badly pitted/corroded. (Also fixed with KidV's solution, or Hotshot relay).
4) It helps solenoid plunger move a RCH (JUUUUST a tiny bit more- LOL!) to make a good connection when you have badly worn solenoid contacts.
Hi
Griswald,
Glad you brought this up to the forum before wildly guessing and replacing parts, which may not be defective after all. Leave that method to incompetent/shady shops who want your money for their wrong guesses.
It could either be:
1) Wiring flaw on 22R-E's (yours has a starter relay), OR
2) Bad starter solenoid contacts.
But let's not jump to conclusion...
What engine do you have?
Please let us know
exactly what clicks:
The starter relay only? (Sorry, I do not know where it is located on an 89.)
The starter solenoid as well?
Without seeing schematic for your 89 4Runner, I could not be absolutely sure that it has same wiring flaw as the Mid-86 to 88 22RE's.
22R-E's Earlier than mid-86 do not have a starter relay so KidV's solution would apply.
However, you can:
1) Post schematic of your starting system, and/or
2)
try this to directly energize the starter solenoid from the battery while trying to crank, and let us know if it
consistently cranks.
Then, well go from there. I'm sure it's a simple problem, easily fixed with a clean robust solution
It's a Toyota, we'll get it running well, no matter what
