My quantum d4d is not supplying diesel to injectors . And it does not start

It seems like you have already checked most of the common causes of a non-starting engine. However, there are still a few things you can try:

Check the fuel system: Make sure that the fuel pump is working properly and that there is fuel in the tank. You can also check the fuel filter to see if it's clogged.

Check the battery: Even though you have two batteries, it's possible that one or both of them are not providing enough power to start the engine. You can have the batteries tested to make sure they are in good condition.

Check the glow plugs: If the glow plugs are not working properly, it can cause the engine to have trouble starting. You can have the glow plugs tested to see if they are functioning correctly.

Check the compression: If the engine has low compression, it can cause it to have trouble starting. You can have the compression tested to see if it's within the manufacturer's specifications.

If none of these suggestions work, it might be best to take your vehicle to a certified mechanic who can diagnose the issue more accurately.

a D4D diesel engine in a TOYOTA HILUX
well all filters good (air and fuel)
all diesel fuel lines purged of air and at spec pressure
good fuel pumps.
glow plugs not dead,(all)
get the service manual and it covers injector changes steps.
fuse good? to pumps. (lift pumps etc) many pumps can not pump air so must be primed.

You didn't say what year, but almost all hard start and soot problems with a diesel is caused by the glow plugs. Check the underhood fuse block for the glow plug fuse and if it's blown you can replace the fuse and if it blows again replace the glow plugs as well. I hope this helps. Take care.

You need to drain the sediment trap. Your owners manual should give you the procedure.
