Even a heatgun may get you over the line.

I can't speak to your car specifically but in almost every instance personally, a rebuilt OEM exchange unit has lasted far longer than an aftermarket unit.

Good outcome. Glad it is going to be saved!

That would be the fuel gauge, on/in your cluster

Remove fuel pump assy from the tank and check your sender operation using a multimeter whicle manually lifting the float- the ohm readings will be in a FSM. Check continuity from fuel pump connector to connector in cluster - this will verify the wiring is good. Check for dry solder in the cluster - an indication of this is if you can thump the top of the dash, and the gauges work momentarily. All this fails, you need a new gauge.

What Dan said, Run a multi to the positive terminal on your alternator and see what its doing.

Try disconnecting the wire to the air conditioning compressor, sounds like the compressor is bad- possibly sticky when engaged.

Any coolant smells? Check your heater core, check for rust in the bulkhead up behind the bonnet hinges too. Failing that have your windshield resealed, I had mine done about 12 months ago.

Plenty of rust-free WD21s going begging over here in Australia. They are almost exclusively rust free and no-one wants them sadly.

LN106 Hilux or RA Rodeo fit with some slight modification. You need to make your own mounts though. I have an LN106 one here I am slowly getting around to fitting

My first instinct was to buy a complete car but the KA powered D22 is actually quite a rare thing over here, they were quickly eclipsed by the diesel engines. I have found an intake, looking at the runners I am not sure how good it would work if I was to adapt my existing Weber DGV to the old throttle body position. Dual side drafts would be nice but that will kill economy. I'm all sorted with the distributor. The other option is to go to an aftermarket EFI ECU management system like a MegaSquirt, which some of the Ratsun guys are running.

So the old slug has been going wonderfully, except for a failed fuel pump (changed on the side of the road and was still in time for work!) The Z 24 is getting tired, it has over 500,000km on it. Many years ago I was contemplating the Twin Cam EFI KA24 engine swap. Well, I came across a low KM engine this weekend gone. I am not sure whether to adapt late model (D22) Factory manifolds and EFI or whether I am gong to try and run a carburettor for simplicity and ease of maintenance. Either way it will be a huge improvement!

Nothing wrong with that! I just bought back my '86 2 door that I sold 4 years ago, and paid twice what I sold it for, and probably twice what I would have paid if it wasn't my old car.

Welcome Willaay I'm not usually a fan of 4 doors but that is a thing of beauty and I think it was worth every cent!

Check your grounding is good to the pump too, and make sure your fuel tank is clean and the sock at the bottom isn't blocked.
