Car wouldn't start, replaced fuel pump, relays, coil, distributor, and fuel filter. Engine has spark, and will start with gas poured into the carborator, but will not run after fuel is gone from the carb. Seems like fuel pump is not getting power. VERY frustrated! Any suggestions would be great.

Your description is too vague to give specific advise. However, if you are stating that the engine turns over when you turn the key but it wont run, then you want to check a few possibilities. Fuel, Spark, compression. Make sure the engine is getting fuel. Then check for spark at one of the plug wires. Then check cylinder compression. No fuel can be a fuel pump, plugged filter, or pump electrical connection, like pump relay or wires. Spark problem can be ignition coil, coil pack, distributor module, distributor points. Compression can be piston rings, valves, head gasket. This is not everything, but it may help you!
Check for fuel, spark, and then compression. Fuel problems can be pump, pump relay, fuse, filter, line, etc. Spark problems can be distributor module, distributor, coil packs, power to distributor or coil packs, plug wires. Compression problems would be piston rings, piston walls, piston rods.
MAKE SURE DISTRIBUTOR CAP ,ROTOR, SPARKPLUGS AND WIRES, OKAY IF ALL HAS BEEN REPLACED.IF NOT GETTING SPARK PROBLEM COULD BE IGNITION COIL FAULTY, ASD RELAY FAULTY,DISTRIBUTOR WITH CAMSHAFT SENSOR FAULTY OR YOU HAVE FAULTY PCM. CODE SCAN VECHICLE FOR FAULT CODE, IF YOU ARE GETTING SPARK PROBLEM IN THE FUEL SYSTEM, CHECK FUEL PUMP RELAY AND FUSE MAKE SURE FUEL FILTER BEEN CHANGED AND FUEL PRESSURE IS 39 - 41 PSI. CHECK FOR FUEL SPARK SEE WHAT GOING ON, VECHICLE NEEDS FUEL OR SPARK TO RUN IF ONE NOT WORKING ENGINE WILL NOT START.
REPLACE DISTRIBUTOR CAP AND ROTOR.AND PLUGS WIRES.IF GETTING NO SPARK TO PLUGS.CHECK SEE IF IGNITION COIL GETTING POWER.IF NOT CHECK IGNITION FUSE.IF POWER GOING TO COIL.FAULT EITHER COIL IS OPEN OR FAULT IN THE IGNITION MODULE IN THE DISTRIBUTOR.
You've already eliminated the spark plug & wireset, distributor cap & rotor. Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.
Components checked/replaced during a tune-up are: air filter motor oil motor oil filter breather filter fuel filter(s) fuel strainer PCV valve EGR valve spark plugs spark plug wires ECM or distributor cap & rotor cabin air filter transmission oil filter transmission oil engine coolant check all vacuum hoses and lines

if no codes or check engine light try spraying with starter fluid if starts or ignites u have spark /no fuel check fuses and relay for fuel pump -check fuel filter fuel pump fix or replace parts -no spark but have fuel check distributor wires and plugs coil
