i just bought a 1990 4runner for 400.00 bucks. just had head gaskets
and a ton of other work. the vacumn switch in the power steering pump was bad and was letting fluid into the intake and smoking like crazy.
got that fixed so now i have power steering. ive noticed the vacumn lines dont seem to be hooked up right. can someone send me a pic of the vacumn lines specifically from the 4 valves on the fender well and the two lines from the power steering pump switch (vehicle stabillity control).
please help as the book is no help.
i also have a rear abs light on. has anyone got diag info for the abs.
haynes says take it to the dealer. not an option.
im an ase certified tech but info is limited thanks fellas jason

 

I attached a couple of pictures to this reply. I'm not sure if it worked though. I just pulled the intake off my 90 to replace a leaky injector so I have pictures of my intake and some notes for the vacuum hoses. We'll find out how good they are in a couple of days
I'm also giving you a "bump" because I know they are a few other members doing top end work to their 3.0 and they may have more info.
Good luck!

 

i dont know how to link it but a member did convert a service manual from a '93 to a website, search '93 service manual online and you should find it here. my abs light was on as well and if i remember correctly the abs system also works in conjunction with the power steering system so you might want to try and start there. sorry i dont have anything specific but that manual should help.

 

Does this help you out at all?
