My FJ60 starts but will not idle, dies immediately. Have renewed plugs, points etc, cleaned rotor and set timing. Dies as soon as starter motor disengages.

Sounds like you are starved for fuel. Look for a pinched off fuel line or a plugged up fuel filter. That would be my first place to start. Possibly even a bad petcock on the tank.

could be
Starter
Spark plugs
plug wires
Distributor cap and rotor
Ignition control module
Ignition Coil
Fuel Filter

Clean or replace the contact breaker points. Set it with 0,40 MM.

fuel pump, filter and ejectors maybe bad need to check those three

Pull the distributor cap off and watch the rotor as you crank the motor. If the rotor doesn't turn your timing belt is broken. If the Engine is actually firing while you have the starter engaged but dies immediately when you let off even when you press the accelerator check to make sure the starter isn't staying engaged in the flywheel as that will kill the motor and burn your starter out. If all is good so far do a compression check. If you don't have good compression on all cylinders your engine maybe firing but with no compression will not run.

It could be many things so start with the easiest /cheaper first.Check your plugs , they will tell allot...white= too lean .black and/or wet =too rich .. clean and gap If your coil is old and not sparking hot enough it will sputter and stall . If your ground to the ignition is loose or corroded , same result. If the motor has noit been run for a long time ; replace spoark plug wires , coil , pioints, rotor , cap ( just replace the distributor with electronic etc.) . Put in fresh fuel (gas goes bad) and filter.You might run some carb cleaner or rebuild the carb , your start /idle jets might be plugged.Check all vacume conections , cracked or loose hose equals too lean to run when cold. If all else fails loosen the distributor and swivel small increments back and forth until it lights. Oh yeah , if your alternator is not putting out the motor will kinda start then die beause the battery cannot keep up.
Good luck

SOUND LIKE PROBLEM IS IN THE FUEL SYSTEM AND TIMING OFF.CHANGE FUEL FILTER HAVE FUEL PRESSURE CHECK.IT SHOULD RANGE FROM 34 - 40 PSI AND 53 - 59 PSI.SHOULD BE NO LOWER.IF FUEL PRESSURE GOOD.HAVE TIMING CHECKED.MAKE SURE PLUGS + WIRES GOOD ALSO CAP AND ROTOR.HAVE INJECTORS CLEANED.ALL THIS COULD CAUSE THE PROBLEM YOU HAVING.

Check the idle speed and the fuel mix settings.

HI, your assessment is correct. this is a fuel filter and pump issue. i would also add a fuel injector cleaner after the replacement of the fuel pump and filter. this will scrub the fuel system and clean any debris that may exist at this point. Techtron injector cleaner is the best solution when cleaning the injector system.

I would also inspect the spark plug wires for faults as well. make sure they are fitted tightly over the plugs.

You may have a problem with idle speed control motor or ETC as GM calles it. here is a photo and a price from rockauto.com.
