troubleshooting

The last thing I want is an electrical fire so coming to the IH8MUD brain trust for thoughts. There has been a few times after driving the battery seemed too low to efficiently engage (original) starter. I’ve kept a battery tender on the battery so it’s fully charged when needed. I recently...

I’m trying to trouble shoot a pressure failure in my n.d. 80 series pump mated to a 86’ 60 series PS box for eventual installation in my 78’ 40 w a 2F. I’ll be building a custom bracket so the pump can go on the drivers side (LHD). I have a PS pressure testing kit spliced into the setup. I’m...

My FJ80 started randomly not starting. When the key is turned there is one loud click but doesn't start. I can hear the fuel injectors pumping fuel in. Battery is fine, spark plugs are fine. I'm guessing starter but with one loud click and no other noise I'm not for sure. Typically if I would...

Forgive the long story, but it might help isolate the issue. My family and i went camping a few weeks ago and on the way home the 1997 Land Cruiser 80 series (US 1FZ-fE) started running rough and the check engine light was flashing. I pulled over and pulled the spark plugs to see if I could...

Hey All, I’m a 17yr old with no clue on a lot of stuff but am trying to learn, I have a 1989 hj75 with a 2H and my car has had a lot of trouble starting, putting out big white clouds (assuming unburnt diesel) so I have concluded it’s the glow plugs. After looking under the hood at the buzz bar...

I’ve been chasing an intermittent issue with lockup not engaging at highway speeds. I know there are general conditions that the ECU needs to see to enable lockup such as speed, oil and and ATF temperature, but maybe 50% of the time lockup does not happen when these appear to be met. When...

Hey guys, Need help troubleshooting the left front while in 4 wheel drive. When in 2 wheel drive and hubs not locked, it drives and turns with no problems. Hubs locked and in 4L, it goes forward and reverse no problem as long as the wheel is straight. Turn the wheel and get a clunking noise...

Got P0037 code and replaced both downstream O2 sensors with Denso. Code came back on and took to my local shop but they were unable to diagnose and suggested going to dealer who may have better diagnostics. Any ideas before trying to navigate stealership nightmare?

I have a LC 100 99 model with 450 000 km. Last week I started to experience problem with charging - for several hours - no charging emptying batteries with no charge lamp. I bought a voltmeter for the lighter port to closely monitor the voltage as my garasje have not been able to fic it...

I recently replaced my rear drum brakes on my '75 FJ40. The front has disks and the PO recently had new shoes fitted. After flushing the whole system I kept it on the jack stands and ran the engine in 2WD. The wheels turn, but the brake pedal goes straight to the floor. Looking at the master...

Greetings fellow enthusiasts, Things have begun to go south on my '10 LX with ~95k Miles. A few weeks back I flushed my AHC with 0 initial problems, I followed the guides posted here including using the Metal can AHC Oil and I bled multiple times until the fluid from bleeders was perfectly...

Hi All, Could I get a sanity check on normal behavior of the fuel pump relay (FPR). I'm trying to determine if I should be observing cycling of the FPR back and forth during engine warmup. By observing, I mean hear it clicking and feel the relay cycle periodically by putting my hand on it...

So, yesterday I went to turn on the A/C (whole house - turned on from thermostat) and just heard a buzzing from the basement. Turned it back off and went down to take a look. Checked the fuse and then pulled the covers off the furnace to take a look at anything. Nothing seemed out of order and...

I am trying to chase down a new noise under the hood. Its a sort of "swish" sound that may be either bearing or clutch related on the AC compressor. It cropped up at the end of a long road trip recently. As far as I can tell its coming from the AC compressor pully area. Can I remove the AC Belt...

Anyone have guidance or a link for air locker troubleshooting? I finally got my new to me 80 out on trail and got myself hung on an obstacle where my locked front should have pulled me through. My friend said the front wasn't turning despite being fully locked according to switches and...

Hey Y’all, My auxbeam switch stopped working recently, and I’m having some difficulty with troubleshooting. Below is a picture of the switch and information on voltage readings taken with my multimeter. Any thoughts on what might be the issue are greatly appreciated. All voltage...

Hi All, I just took delivery of a 97 LX450. The previous owner had replaced the brake booster and wasn't happy with the job the shop had done (not a Toyota specific shop). I knew that I'd have to put some time into this and I'm going to be working on it this afternoon and tomorrow. Does anyone...

Hello wise FJ lovers, I would like your help diagnosing some strange problems with my 1976 FJ40 Here they are: When first turning over, the starter spins slower, then gets faster the longer it spins. This may take a couple 5-10 second cranks, with the starter spinning faster and faster the more...

I just picked up my Toyota 1987 extended cab SR5 22r last month and drove it from Arizona to Kentucky. I took it out hill climbing and mudding for about 5hours. Was in 4wd and 3rd gear going fast over some mud and the engines rpm was going up without me pushing on the gas and in neutral so I...
