2000 Toyota Corolla 4 cyl Automatic 116000 miles

My fuel pump was going out so I had it replaced. Then it wouldn't start so we changed spark plugs. And NO luck so we changed Fuel filter and still NO luck! The fuel pump is running and the injectors are working but the car still isn't running! We can get it started if we pour gas into the air filter and if I slowly press the gas pedal the engine revs up but if I try to give it too much gas at one time the engine dies out and won't restart! The car was running before we changed pump so I don't think it is anything major but any help would be greatly appreciated!

Thanks So Much

You need to measure fuel pressure at the fuel rail with a mechanical gauge. This will tell you if fuel pump is problem. While the pump may be running it is the fuel pressure that runs the car. It should be at least 45psi.

While pump is new, it may have been installed incorrectly, or a hose on the pump may have worked loose.

OK so I got the diagram for the fuel pump and pulled it back out to be sure everything was put in correctly and now I have another problem. The cap that goes on the top of the main filter is plastic; Correct? I believe so well the guy who put it all back together lost the cap. Where can I get another one? Also there is a little rubber piece that I don't see on the diagram but I know when we pulled the old one off it came out. Not sure where it goes. Will that cap keep it from running?

You should be able to get any parts from Toyota. The pump should run with those pieces missing, but they may affect pump pressure.

You need to know what the pressure is before you can diagnose fuel problems.
