I think I figured out why my glow plugs don’t work. Checked the resistance of all the plugs and they’re each around 4.5 ohms. Wiring connections look decent. I checked for power from the starter switch when turned to heat and nothing! So a new starter switch is ordered.
Now, to figure out why my crawler has started bogging down excessively while running and I have to prime it with the pump above the filter each time I want to use it...
Last weekend when this issue appeared I changed the fuel filter and blew air through the fuel line from the filter back to the tank (with the line disconnected from the tank). The issue has persisted after a few hours so I cut apart the filter I removed to find this:
Maybe a mix of biomass/algae and rust?
So it looks like I need to drain the tank, blow some acetone through the fuel lines, try to spray out the tank with brake cleaner or something, add a water drain to the tank (thanks previous owner for removing that), and fill it with fresh fuel.
Any other thoughts/suggestions?
I’m also missing a torque converter temp gauge and want to fix that. I haven’t found where the temperature sending unit goes for the gauge. Looking from the seat/rear, does it install on the lower front left of the TC housing? There is a wire running down there that runs up to the gauges and connects to nothing, like someone had an electrical temp gauge installed at one point, if that is the sending unit location.
Also, the bottom of the steering pump and trans pump are wet, so there’s one leak found. Now to find where the engine oil is leaking.
