If you are checking before the pressure at the fuel line in the engine bay, then it is possible that the filter may also be an issue. In most instances, the filter is somewhere along the fuel line from the tank and would be underneath the car's trunk. In some cases the filter would be inside the tank together with the pump.
If at the tank's outlet the pressure is relatively low, then as you posted, it could be the fuel pump which is inside the tank. It is also possible that dirt, sand, debris may be blocking the inlet port of the pump, try banging on the tank to agitate with the pump off. Cleaning/replacing the fuel pump would of course necessitate tank removal.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

Yes sir , you have a failing valve, soon it will snap in two....please have your head checked. You can do this yourself by placing a long-handed screwdriver , business end down to each cylinder while pressing your ear to the handle(while engine is running)...you will notice a definite difference when you hit which cylinder has the bad valve. Also makes sure the egr valve is clean and your exhaust recycle valve is not stuck.( located in the crossover pipe)

SOURCE: fuel pump relay
first alway check the simple things first like fuses and relays then start playin with changin out parts. under the hood you sould find a fuse panel if the lid does not tell you what is what you need to look into the service manuel find the fuel pump relay and switch it with the same type relay can works some the doesn't effect the engine like a fan relay for expamle. then try to start engine when turning key to the run pos you sould hear a fant hum or whine from the pump. if thats a no go take the main fuel line off before the fuel filter and see if a good stream of fuel comes out when you turn key to run pos.if so replace fuel filter.
