troubleshooting

Ahoy mudders, I've been troubleshooting a SRS warning light issue on my 2007 Land Cruiser utilizing the procedure outlined by Cosmo Kramer in this post: Air Bag Light, Diagnosis and Repair - write up - https://forum.ih8mud.com/threads/air-bag-light-diagnosis-and-repair-write-up.1267640/ I've...

Hey everyone, I recently imported a 2000 VZJ95W and has been a bit of a problem child since the get go.it was making a noticeable chirping squeak sound since arrival and been trouble shooting what it could be. I then noticed that my coolant reservoir was quite low and after filling it a couple...

Going to be troubleshooting my ECM. Thought I'd start with a post. Did a quick search and only found a few threads with mention. So figure this would be a good place to store a how to troubleshoot and replace. History is that I had a fire over the passenger side exhaust manifold. This...

After putting the truck back together f/ a rebuild in the fall, I couldn’t get the A/C to work. AC blew ice cold before tear down. Here’s where I’m at: new compressor / clutch, after market dryer relocate, new condenser, system purged and charged at local AC shop. They dicked around with it...

I think my issue is centered on the AFM in my 93 LC. Originally, I purchased it in non running condition and in troubleshooting I found that the two screws in the AFM had been removed. I soldered the connectors in the AFM and the truck started and ran. It passed smog here in CA and ran until...

I've researched a lot and watched many Youtube videos... I'm still at a loss and need some advice. Thank you in advance! The EFI 15 amp fuse keeps blowing on my girlfriends 1995 80. The Cruiser will travel 10 to 12 miles when cold, then the fuse blows. It then blows a fuse every .5 to 1 mile...

It was a little bit warm today after work. So I tried to turn on the air conditioning on my '99 Land Cruiser and it did not cool off at all. Outside temperature was showing to be 81*F and the soil temperature gauge I have mounted inside one of my vents was showing the same with the blower on...

Just some background info in case it helps. 1997 1fzfe 80 series 315k miles. Recently installed a new exhaust system which blocked off the EGR port. Ran fine for 3 min after the exhaust install then died and never started again. The motor turns over and it starts for about a half a second and it...

Looking for troubleshooting help. I have a 94 LC with A442F transmission (US specs). All of a sudden it would not engage in Reverse and it will stall if I shift to D 2 or L. When the transmission wire harness is unplugged it will go into gear (I think that puts it into safety mode?). Thought...

Yesterday I was triumphantly driving around my neighborhood with my buddy who assisted me in replacing my leaking clutch master/slave and hardline. Suddenly the engine ran rough, backfired, ran for about 50 yards and then died. No spark. Troubleshooting this morning and there is no spark to the...

I was absolutely certain my cold weather no throttle issue was a bad accelerator pedal position sensor (APPS) from everything I found online. Bought a new OEM throttle body with APPS, TPS, and throttle motor last winter and after riding it around in the back floor all year, I finally installed...

I have a 2000 LX470 with about 270k. I replaced the entire throttle body with a NEW OEM unit to fix what I thought was a faulty APPS. I have the same problem and today seems a little worse. Background: This vehicle is normally garaged and a second vehicle. Last winter I had two occasions where...

Gday everyone I would just like some ways of troubleshooting my temperature gauge (1979 fj45 2f) it does not move at all along with my oil pressure and alternator gauge. So far the only trouble shooting I have done is removing the temp sender, visual inspection (looked good) checked resistance...

'97 80 Series LC with 300k. No recent work other than oil top off's 🛢️ I will try and keep this short. I know there are several other threads pertaining to causes and troubleshooting of the EFI fuse blowing under various conditions. But none matched my exact scenario, so I am hoping my specific...

After doing some fuel system work I was driving my LJ78 and it just stopped. Enough fuel. Injectors are dialed in and getting fuel. I don't think that was the issue. So I looked a little more closely. I found that a fusible link was burnt out. The link ran to the glowplug relay (orange arrow)...

1999 LX470 - 200k Hey there, odd issue that happened out of the blue and looking for guidance on the next steps to take to resolve. My fob no longer controls the security alarm and when I unlock the car, the alarm goes off. Also too, I noticed that the horn pad didn't work when I press on the...

As I wrap up my Parking Brake rebuild on my 75 FJ40, I am trying to figure out the Parking Brake Switch circuit. The switch works fine. I have it operating correctly (based on my multimeter) when the brake is set and released. The problem is with the ignition on and the brake set, the brake...

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...
