I recently just bought a 97 chevy ext cab 4x4 with a 5.7 vortect with 125k miles and was running great for a week and now when i go to turn the key to start it turns over but just not wanting to start,I put whole new spark plugs in and changed the fuel filter ( which was dirty inside ) and still doing the same thing.Now people are telling me that it could be a fuel pump so I looked online and see how to tell if the pump is workn and they said you will hear a buzzing sound for a second (which I do from the pump) when u turn the key and the other ways are to open the filler cap and listen for the pump which i hear as well.fuses/relays look good also.So im thinking its the starter/fuel pump going out on me.when I bought the truck it did came with a autostart key remote to start the truck from a distance which has problems startn so thinkn that could be the cause of it? any help would be greatly appreciated!

 

whats the fuel pressure key on engine off should be 60-66psi ?whats the pressure when running?does it hold the pressure for a awhile or does it bleed off right away
