check for battery voltage at battery should be over 12 volts, try jump starting to ensure your starter is good, once started check for voltage at battery should be over 13.5 to ensure charge system is working if system is charging replace your battery

I would check the fuel pump relay first. You should have some fuel pressure in the lines when you turn the key on. The relay is powered for 3 seconds to boost pressure until the engine starts.
The relay may not be working or the check valve in the pump may be letting fuel back into the tank which would cause the pressure to drop to zero when the engine is off. You should have at least 15psi with a TBI system and 35psi with MFI.

well i would suggest to go to the car shop for that, it wont cost that much.

Which engine?

I would first check the following:
Are you getting spark at the spark plugs? If not, check the ignition coil or coil pack.
Are you getting fuel to the engine? Make sure there is fuel in the tank, and that the fuel pump is working.
Check all your fuses to make sure they are OK. A blown fuse to any critical engine component (ECM, ignition, fuel supply) will prevent a vehicle from starting or running.

On the vortec engines they require 56 pounds of fuel pressure to start a few pounds shy of that you have a dead vortec you will need a fuel pressure guage to verify

Your problem may be one of the following:
First check or just replace the fuel filter. Usually located under the car in front of the rear axle, drivers side.
Next, the fuel pump may be worn out. Usually they get loud or stop working (running).
Next, check the fuel pressure regulator. Usually located on the front fuel rail, drivers side.
Is the vacuum line attached? Not leaking or rotted?
Also, do you smell a strong fuel odor when it won't start? May be one or more stuck-open injectors, or the coil pack is bad.
Checking these in the order listed will more than likely fix your problem.
The clicking noise indicates the battery can no longer run the starter, which also means the fuel pump won't run either.
It could be a fuel issue. How old is the fuel filter? Can you hear the pump run for a few seconds when you turn the key on? Try turning the key to ON without trying to start engine three times waiting for the pump to stop running each time. Then try to start the engine. If it starts, Its a form of Vapor lock caused by the extreme heat we have had lately, and a weak fuel pump.

If none of this works, try a new fuel filter first. From there have someone check the fuel pressure regulator and then the pump. If you are in need of a new pump, take my word for it and spend the money to get one from a Dealer, and not from your favorite parts store. Most parts store parts are made in China and they are JUNK.

You don't need to bleed the coolant systems in 1999. Fill the radiator and fill the overflow to a point mid way between the cold and full lines. Warm up the engine until the fans cycle on and off. Let engine cool down and check level in the overflow. Add as needed and keep a watch for a couple of weeks. Any air in the system will be pushed out of the radiator into the overflow bottle. When the engine cools down it pull coolant from the overflow back into the radiator.

I need a bit more info, just what is it doing, or not doing?

You said you have fuel flowing from the inlet line of the injection pump? But not at the injector lines?

If it ran when it went in there, it should run when it comes out but start at the basics, fuel make sure you have fuel pressure in the fuel rail port, then make sure that you have spark, if you have both then check engine timing belt alignment.
