Sounds like you are doing it right. Double check that you are removing the efi fuse and not the starter system fuse (the fuse below the efi fuse). Here is a link to the fuse diagram...

I am not speaking from experience… but there was/is a thread or maybe it was a YouTube video of a van owner who installed a Subaru turbo in a vanwagon along with a ton of other modifications (they...

The motor mounts could be a possible issue. The shaking could be from the motor bouncing around on wore out motor mounts when the rpm’s drop. I noticed a significant reduction in vibration after a...

Thanks captain! They say the housing is glass, I ask to see if the lens is glass. How long have you been running your setup?

thanks Jan for sharing your setup. There are no in-depth inspections...

So I drove my van through Santa Barbra, Ca in one hell of a rain storm. I was driving 35 mph on the freeway and could barely see with the amount of rain coming down. I ended up hitting a lake on the...

Hey vancation, fusible links are the common issue that can cause this. Google search for” fusible link thread Toyota van tech”. Should be up at the top. Not to hard to fix, but may want to figure it...

Thanks Original, that makes sense.

Ok an update. I am trouble shooting the cruise control system starting with the diagnostic codes. I did not know that the vans had this till I started reading the body electrical section of the...

I posted a wanted add for a CC cable, but have a few questions regarding the cruise control cables. I’ll update that post based on info collected here.

For LE manual transmission vans is there a...

Yeah my van bucks at low rpm around turns if I don’t coast the turns. The motor mounts wear out in about 40k miles ( I have replaced mine twice in the last 80k miles). You will know their toast when...

The new pulley resolved the noise. Wow what a difference! While I was at it I replaced the PS return hose with 19/32 PCV hose and took apart the reservoir and cleaned the screen. After I was finished...

Sorry to hear about you tranny. FWIIW If I still lived in Portland, I would have let you have the tank off my 4wd parts van. Having that low range will be cool. Reminds me of the marlin crawler dual...

Well to be honest I thought about hammering it out. But that usually does not end well.:roflmao:

I had not thought of that! I ended up buying a new one. It came in today, hope it works!

Well I took a closer look at the PS pump. I found that there is a dent in the PS pump pulley v-groove. This dent makes a bump where the belt slots into the pulley. I think the noise that I am hearing...

Anyone ever have power steering system making a rattling/loud ticking ( almost like a stuck lifter) type noise? Mine has had this noise ever since I owned the van. A little background, the PS fluid...

Have you tried pulling the the diagnostic codes? Here is a helpful link to doing it if it is new to you....

The 1.25B fusible link failed on my van this weekend. I started the van up and drove a short while when I noticed the charge and brake light came on. I pulled over and turned off the van to check the...

Does it run fine once it is warm? Maybe try to rule out a leaky cold start injector. Can you disconnect the cold start injection harness plug for the cold start injector easily? Mine van has a...

:doh: I rechecked the fuse panel and discovered that the ignition fuse was missing! Plugged it in and started right up.

After reassembling the timing case/chain/cover to replace a snapped water pump bolt the van won’t fire. When I first tried to turn the engine over the battery was dead ( I had battery disconnected...

I forgot to mention removing the support bracket that is attached to the bottom on the intake manifold down to the engine block (it also holds the ground wire) and the support bracket that attaches...

This blog was super helpful. In my case one of the two long water pump bolts sheared while I was replacing the water pump gasket. What a head ache!

I tried an easy out once, but given the bolts...

I replaced the front motor mounts this weekend on a 1988 LE 5spd 4x4 using WESTAR PN EM9029 from Rock Auto. They had the Toyota PN stamped on the insulator the same as Tim posted in post #10.

For...

Wow that’s great! Have you installed them?

Pulling the efi 15 amp fuse will keep it from running. It won’t keep it from turning over.

Hey TVN, I have a 1988 van but it had the code for 4-3 for the last 8 years ( same code and error description in the service manual, but no description on how to repair). Until I saw that the fuse...

Hey MrJustin, welcome to the group. Congrats on your new van. Half joking, but you may end up being the best mechanic for your van. I would imagine most of not all common issues with our vans are...

I eventually past CA Smog and thought it would nice to share the progression of emissions improvements as parts were repaired/replaced. While not all variables are held constant, I think it provides...

This is exactly the answer I need for an issue I have been struggling with.

I had a failed air idleup diaphragm. It was basically routing unmetered air through the large port, through the...

Hi All,

Lately we have been finding an increasing number of Toyota Vanwagon parts becoming no longer available (NLA). But I have had some luck using alternate parts from other Toyota Models or...

Thanks JDM, I don’t have a service manual (yet) for my model van. All the repairs I have done were using the pdf 87 service manual and 88-89 diagnostic codes pdf available here on TVT. It is not...

I have had code 4-3 since I bought the van. I always thought it had to be an issue with the ECU. Turns out I was wrong, for me it was something super simple. A fuse.

if you ever get this code...

Hey Larry, if you have not already looked at diagrams of your models air intake it might help you locate where they might be. A member recommended this site https://partsouq.com/ which I have found...

Update. Got the EGR vacuum modulator in today. It appears exactly the same. I installed and ran the ERG Diagnostic test per the Toyota repair manual, and it performed as indicated. See below images....

I am happy to say I figured it out. Below is a diagram with where the exhaust gas runs from the EGR, through a channel that is cast in to the manifold (drawn in red), and exits into the intake...

Hi all, I have been trying to track down an issue with my ERG after failing smog. I was commenting on another thread but I believe I have found the issue. All the EGR components check out and are...

Update. I was able to get all the ERG components off. They all are working properly. The EGR Valve diaphragm works. The diagram is able to open the valve and hold the vacuum, allowing air to pass...

Thanks Theojo! After doing this it did not affect how the engine ran. It would seem that either the EGR is stuck closed or clogged. With the engine off, and sucking on a tube attached to the port, I...

Thanks Gareth! this is exactly what I needed!

Hi all,

I have decided I need to have a OEM Repair manual for my my 1988 LE 4x4 5 spd. I have been doing some research on which manual corresponds with my model. My VIN starts with JT3YR36....

Any pointers on what port to run the vacuum lines to apply vacuum to the EGR in the second image of post #95? Thanks!

Most likely the next visit, as I mentioned to the tech that I had changed the cat in Oregon recently. haha hopefully not...

Thanks headhunter38 for the tips! The cat is on this of possible suspects, I did replace it five years ago but with a none CA cat in Oregon. (I don’t know if a none ca cat matters). They just are so...

Hello All, I recently moved back to California from Oregon and needed to get my 1988 5spd 4x4 California Emissions Van smoged. It failed:no:. Below are the test results.

The way I...

That is crazy, when I first read the I have to admit I thought it was a joke. But my dog hates squirrels too. If he got one cornered in the engine bay… who knows.

Hi Armorell,

With regards to loss of power the Service manual (can be found and download for a thread on this site) has pretty good trouble shoot on the subject. Did the tune up include rotor,...

hey Socal87, I just replaced the tps on an 1988 5spd 4x4. Initially when I changed the tps, I did not know that the TPS needed to be set position per Tim’s video. I continued to set the timing to 12...

I set the TPS in the van this weekend, and it cleared the 5-1 code that had been having.

I got around to buying and installing some parts. I pulled the broken out ebrake cable out of the cable housing and ran the new aftermarket cable through it. The cable I purchase from eBay had nearly...
