Could this be somethin clogging the fuel lines?? I put an all-in-one fuel cleaner in and that also worked temporarily. When I try to start the car, it turns over and shuts off immediatly. Also I smell gas when i try to start the car. Fuel is being pumped to and through the fuel filter so from the rear of the car back it is ok. Possible leak in the fuel lines? Would a faulty sensor cause this? I guess my overall question is why does it work only temporarily???

let me explian why i replaced the fuel. i purchased the car from someone who let it sit for a long time (not sure how long, over a month) and i think they were putting fuel additives in it. not sure, but i strongly believe so

fuel pressure reg is fine, removed the vacuum hose and nothing came out

If you are smelling gas, you most likely have a fuel leak somewhere. You do not say what type of vehicle that you have (make, model, year, engine. and transmission are things we need to know to help) so I am just guessing at the cause.
Are you sure it is a fuel problem? Have you checked for spark when it will not start? If you have no spark, you will smell fuel because unburned fuel is coming out the exhaust!
It sounds like a sensor or a control module problem.
With more information, I could give a better answer!

I once chased a "fuel" problem for days only to find it was a coil going bad.
1st- check for good spark at the plugs. I use an old plug, clamp it to a good ground w/the plug wire attached.
2nd- if weak at step 1, try a jumper wire from coil output to a gap [such as the same test plug], if weak spark, verify full 12V at coil, if voltage present, replace coil. If not 12V, follow wiring diagram back, may have bad ballast resistor. If coil spark good, check cap/rotor for corrosion & check plug wires for less than 3,000 ohms of resistance per foot of wire. If this is a points ignition it may be due for points & condensor.
3rd- if spark appears okay then check for fuel &/or verify fuel pressure & volume. Check injector spray pattern. Check air filter. Dump a can of Dry-Gas in the tank, it may have moisture problems.
If possible check starter draw, it may be pulling too much current so there is not enough left for everything else.
Keep the battery charged while you work so you do not induce a phantom problem by running the battery low by too much cranking.

fuel pressure regulator and with a dvom and a repair manual check voltage to the pump and the pump relay also clean everythin tank lines injectors etc.

change fuel filter in line and in tank . most new cars have two filters check both

i would remove the tank clean it out.
and blow out all the fuel lines

have you check your fuel regulator. try swapping or replacing relay and circuit breaker.

It is possible that your automatic choke is not functioning properly and flooding the engine.
