I would say that the most likely problem would be the fuel pressure regulator. It could have a number of symptoms and what you describe is one of them. Check out this YouTube video that explains it.
Good luck!

SOURCE: Engine cranks, won't start

That does not sound good. It seems that you may have broken or worn rings or pistons. You could try timing the engine and see if that is not a problem but I think it is a bad piston and rings.

SOURCE: 91 Chevy K2500 5.7 engine will crank but not start.

If you have a electric distributor there will be a spark module in side of it. you need to change that. it comes with silicon that must be put on the bottom of it before you put it on. Also I would make sure that your timing is OK. Pull your #1 plug wire off and put your finger over the hole and turn it over, just bump it in tell the piston comes up. you will feel air on your finger. bring that piston all the way to the top. I use a long screwdriver(turn the engine by hand) then check and see if the marks on the timing cover line up. If it does than change that module.

SOURCE: won't hold fuel pressure

Check the fuel pressure at the shredder valve, there should be 60,PSI to 65,PSI for the poppet injectors to work. If the pressure is correct then there is a good chance that the Spider injection system may have gone bad. Recap. Check the fuel pressure at the shredder valve to make sure the Fuel pump is not going bad. There is a valve at the fuel pump that holds the residual pressure in the system, try cycling the ignition three times. Turn the ignition to the run position for 5 seconds and turn it off and do it again for 3 cycles to pressurize the fuel line and see if it starts. If it does not start then check the fuel pressure at the shredder valve. Make sure you have the proper pressure to activate the injector system. If not then get the injector system check for bad wire harness and see if you can smell gas leaking. Oh and the easiest thing to do is change the fuel filter too. Good luck and keep me posted and if you get a chance get the ECM scanned at Auto Zone for free and look for any DTC codes if any have it cleared. Good luck and keep me posted

97 chevy silverado will not start unless i pour gas in throttle body

Sounds like a failed fuel pump in the tank. Try listening at the opened fuel filler and have assistant turn ignition on without cranking. Should hear buzzing or whirring for a very brief (2 sec.) time. If not... also check connectors and fuses. Could try banging on bottom of tank while assistant cranks over, sometimes will make it work for a while.

1996 Chevy truck won't start until gas is poured into throttle body then stays running, what is causing it?

Fuel pump relay faulty, when the engine starts the oil pressure switch takes over fuel pump circuit and sends power to the fuel pump

My 1985 grand Marquis won't start I can pour gas

Take the gas filter off. Should be located near the front of the carbeurator, take off the air cleaner and look for it, it takes 2 wrenches to take it off, a little gas may spill out but not much and replace it, however there is a strong possibility that he gas pump is out if the filter is fine. Hope this helps

96 chevy blazer won't start.

I'm following another issue like this on a 1996 Jimmy.
This engine requires 60psi or more fuel pressure to run.
You need to have someone check the fuel pressure at the rail- throttle body with a gauge.
