3lb hand sledge and a brass drift from the wheel well side. Just a tiny weep. :)

Yes. Codes are stored in memory. Active codes will throw a CEL when the engine is running and the CEL can clear on its own, but the code remains in memory. This is why it's important to clear codes when troubleshooting. This way you know you're...

If that were the case, you'd get an error code. The most common issues would be an intermittent fusible link or poor/corroded crimps/loose terminals in the relay box. I would suggest a bit of "percussive diagnostics". Give the EFI relay a tap...

You need to go back on that path 1 step. IGT and IGF are reshaped and retimed by the ECU, but originate from the pickup coils in the distributor. You need to scope those 2 before they hit the ECU.

Negative. Jumping B+ to FP bypasses the FP logic (COR/FPR). The B+ comes from the EFI relay.

Get ready for what will feel like the longest work week ever!

Sure. DM your email addy.

Just guessing... 1) Excessive metal particles on the ABS sensors. 2) Bad ABS sensor. 3) Broken ABS wiring. Check for damaged wiring. 4) Excessive movement of a birfield. Check all bearings. 5) Excessive movement of rear hub. Check all...

I use Excel. A single spreadsheet with tabs for each event. Copy the basic supply tab to the end, change the name, edit as you see fit. Color coded cell styles for easy identification. Simple, quick, effective. Been using the same file since 2007.

LOL. After driving my 91 FJ80 for 20+ years, the speed limit is "go the fu*k around me".

This right here is the key to driving a 30 year old 80 Series. Folks should also do the math. Assuming no variation in ground speed over a distance of 100 miles, the time difference between 65 mph and 75 mph is 12 minutes. Your fuel economy...

Mine is also my DD. 15K to 20K per year. I have 379K on it now, original HG done at 145K. Yes, I run up to and will hold 4000 RPM on mine, but doing that for a long run will burn more oil. My valve seals are getting old and weak (as yours...

no. the bracket is different between the 80 amp and 90 amp unit. You need the 80 amp unit with the external fan.

7600 miles in 2017. Jersey to Cruise Moab to Seattle to Vancouver to Jasper and Banff. Took the Trans-Canada back east and dropped into NY over the St Lawrence. 3600 miles in 2018 from Jersey around the Gaspe peninsula. 4600 miles in 2019 from...

I’m up in your area today putting the 80 to work as my repair vehicle.

4K rpm is not high rpm.

FWIW, I don't consider 3K miles a long road trip anymore. If you're concerned about engine temps, then address the cooling system properly. 190@65mph on a hot day (90F+) with the AC on is pretty normal.

We build custom battery ground cables as needed using OEM battery terminal connections and good welding wire.

How did you verify no spark? Have you addressed the low hanging fruit like wires, cap, rotor? Have you checked for continuity between the distributor connector and the ECU? This is all documented in the Toyota EWD and FSM, which are available to...

So, you DO have a CEL when the key is in the RUN position with engine OFF? What brands did you purchase and install for the coil, dist, control mod?

Crank position sensor is internal to the distributor. The ECU uses one of the pickup coils for this.

The picture in the FSM shows the scanner plugged into the diagnostic port on the firewall. That is not the OBD2 port.

A clutch driven fan will always rotate. It will never be "off". Replace with an Aisin FCT-049. Don't play games with any other brand.
