Replaced fuel filter and checked fuel pump. Car fires up but won't stay on. Shot some gas into the throttle assembly and it runs longer. Can it be the egr. Like injectors not working. Is it a sensor?

Connect a fuel pressure gauge. There should be a test port somewhere near the injectors. Watch the fuel pressure. If it drops just as the engine dies, you probably have a problem with the circuit that keeps the fuel pump running.
When you are starting the engine the fuel pump turns on for a few seconds. After the engine is running the fuel pump is allowed to stay on. It depends on how the manufacturer implemented the circuit, it could be a relay, fuse, loose connection or who knows what. Have you fitted the new filter the correct way The direction of flow should be marked on a new filter.

Why does my 1998 jeep Cherokee bog down when I accelerate?
first replace the fuel filter. they should be changed about twice a year. I'm not sure where it may be located. if that doesn't fix the problem. you need to have the fuel pump checked to see if it is putting out the correct fuel pressure. if not it obviously needs to be replaced. if the fuel pump is good and the filter is good/replaced. have the injectors checked. these are the most common issues to be checked first. i wish i could be more helpfull.
