Cold Start Injector Time Switch....is that a different name for Thermo Time Switch?
When looking around I get the above name more often.
Such as this
With the black one looking very similar to the one I'm looking for
Yep, that black one is what you're looking for. It's referred to as any combo of those terms, we'll call it the CSI thermo-time switch just to be on the safe side, K? It's really expensive as you probably just learned so if I were you, I'd test it to make sure it's really no good. The testing procedure is outlined really well on the 22reperformance.com website. I think it involves heating a pot of water and testing with a multimeter at a cold temp and then hot. Your cold start injector could also be clogged, and is cheaper than the thermo time switch, so be sure before you throw over $100 at it.
That looks like the distributor hold-down bolt. That thick washer prevents the distributor from rotating which would change your timing. When you put that bolt in, be sure to use rtv or threadlocker to prevent an oil leak. It's one of 3 bolts on a 22re that require sealant.
I took a look at what the codes meant out of curiosity and you either have a handful of bad sensors, or much more likely some faulty wiring. Check each sensor with a multimeter to see if it's getting power. If not, you'll have to trace a wiring diagram, physically locate the wires-in-question and visually check for corrosion, breaks or damaged insulation. Also likely is that the damage all occurred at the same place. What a pain, glad I have an '85!
CSOUT said: Bump for this thread to let you guys know you helped out another yotatech member. Just received and installed the two seals:
90304-76005(MAIN) CV SIDE
90316-60004(SUB) KNUCKLE SIDE
Fit perfect on my '90 SR5. And this says it all...
Hi all, I know this is an old thread with lots of great info but I spend 40 minutes at Napa looking for this knuckle seal using all the PN numbers on here with no luck. I have a 91 4x4 pickup. Does anyone have a link to the knuckle dust seal part instead of a PN? My old rubber seal that came out of the knuckle fits perfectly over my new CV axle, so I don’t think I need anything specially but I can’t find that standard dust seal for the life of me.
The KOYO-CR PN is off the seal I pulled from the knuckle.
On the older vehicles those dust seals were not vehicle specific however I believe it may actually be called a axle seal!

I realized what I was doing wrong and wow is it embarrassing. Hopefully, you guys at least get a good laugh. I tried putting the seal in with the old metal lip still in the knuckle. Enjoy that for what its worth!

The replacement seals can be difficult to install however I had a 55 willy jeep with the same problem and was told to put the blue high temp grease in the knuckle. Took a while to get it in there with a spoon but that was 25 years ago and haven't had any problems. I was told the the high temp grease stayed thick enough to not run out from around the seal but would thin out enough to keep things lubed. If you do this I recommend you fill it up with as much as you can possibly get in it.
