have the carb rechecked that the float is correctly set and valve is not worn or debris and fuel pressure between 7 to 10 lbs

Go way to test best just to replace it

If you drained you radiator coolant, and refilled it, you may have air in your system somewhere. If you have air in your system, the temp gauge will gradually go up, up, up to where it looks like its going to overheat, but then it will come back down, sometimes below normal operating temp., and then climb back up. If this is what is happening, you need to burp your system. Get a special funnel that allows you to fill your radiator and run your engine until all the air is out.

Overheat & destroy the engine No way you do not know that

It seems to me that you have a bad fuel pressure regulator, but before replacing the FPR locate the fuel filter disconnect the line that goes to the engine and not the one that goes into the fuel tank put a hose on the tip of fuel filter, place a container under to drop fuel now have someone turn the ignition key ON but engine off while you are going to observe for fuel, pressure needs to be strong if it looks to weak then it might be your fuel pump I also recommend to change the fuel filter sense you are there ,also check for power on the injectors connections with a test light, after doing this and everything seems fine then go head and replace the FPR fuel pressure regulator,WARNING working with fuel is highly dangerous make sure fuel doesn't touch any cables or look around for anything that can detonated fire, GOOD LUCK!!!!

You have a blown head gasket

what about your fuel pump? when it get hot it stops and when it gets cool works. It is better as soon as you do have the engine shut off when is hot,try to check if any fuel is coming from the fuel tank to the engine if it doesn't the renew the fuel pump. Also my advise is to ask your mechanic as an expert he does have the special equipment to check the fuel pressure flow to the injection system,or if it is your vehicle fitted with carburettor to check the mechanical fuel pump whether it does send fuel at all. Good luck.

If your not overheating or losing coolant, its more than likely engine oil burning. If it is coolant related, possible blown head gasket.

test your car's electrical system with a different horn, other than the possible faulty one or test the horn itself, outside the car with a different power source, this is to isolate which is faulty , the car's electrical system or the horn itself, if horn is faulty then replace it, if not check your wirings.

aldata.com read chapter, HVAC see core pull R&R lots of steps. read em.

HVAC? my guess is the heater has issues? just a clue here. this old car is damper controlled and no damper motors back when. old lovely simple tech. a knob a cable and the bell crank lever on a damper door. (my online source can not do old 84s.) so will answer in the, pretend im there, mode. i wiggle the knob, i see cable flex, i follow it with my eyes. it goes top the damper, lever, it moves 1 for 1 ratio ,knob to lever. if not?, the cable is bad or not clamped. if lever moves and damper dont, its broken , the damper mech. busted. easy huh, just wiggle and look, gota love old school parts if car was new? the post is 100 pages long. V meter in hand and drawing a max.

on high too, is blown fuse

the flot valve inside carburretar may fails to work(imbalance)

try taking out the thermostat and running without it, also take lose all the cooling system hoes es and running straight water through it to clean out your cooling system.

Most likely a fuel pump problem, locate the diagnostic check connector under the hood and turn the key on then put a jumper wire between the terminals FP and B+ if it start then the fuel pump is ok and the problem may be the EFI relay or efi fuse

If you mean the tail lights, there should be a fuse.

if you mean on the brake caliper, Bleeder valve? If you mean on the firewall, Front proportioning valve?

I'm not sure what a "fream" is but if you mean the main proportioning valve that is located on the firewall of the car. Now you know.

Ignition "modulator"??? I assume you mean "ignition module" or "Ignition control module". If this is what you mean, it is mounted on the ignition coil assembly. Toyota refers to this part as "transistorized ignitor".
