We have replaced fuel pump in a 98 ego metro LSi drove home ran fine. Now it won't start any ideas why it won't start.

Pam, was the fuel filter replaced at the same time that the fuel pump was replaced? If not, replace the fuel filter. Often, the filter will get clogged with debris. When that happens, the fuel pump will be ruined. Replacing the pump without replacing the fuel filter can ruin the new pump. It is also possible that your new fuel pump is defective. Now that most replacement parts are made in China and the third world, there is virtually NO quality control. I'm a professional mechanic and defective brand new parts are a BIG problem in this industry. Was the fuel pump relay replaced when the new fuel pump was installed? Always install a new relay, as a failing [your old] fuel pump will often damage the relay. This will cause problems with the new fuel pump. I would advise that you install a fuel pressure test gauge to the engine. This will allow you verify whether or not the engine is receiving enough fuel pressure. If the pump works but the pressure is low, also check the fuel pressure regulator. The web links below should help you.

FYI, there is also a "sock" style pre-filter on the fuel pump. This also needs to be replaced any time that you replace the fuel pump.

Still wondering if a new fuel filter comes with new fuel pump?

Most cars have a strainer before the pump inlet and a inline external fuel filter. some have the filter and pump as one unit installed in the tank. the fuel gauge and float are attached to this unit . it is possible that the pump relay may be on the way out.

Sorry, if this is a silly question, but is a new Fuel Filter installed automatically/come with a new Fuel Pump? Or do you have to buy a new Fuel Filter and attach to the new Fuel Pump before installin

Has the filter ever been changed? Need to know year and model of the truck. Fuel filters can be near the tank or under the hood. Filters are usually separate from the fuel pump.

97 toyota avalon xls 3.0 no fuel installed new fuel pump it started and then stalled ;no fuel pressure at fuel rail

if one of the o rings on the fuel pump moved when you installed the new pump that may cause you to have no fuel pressure. i have had the same problem once before and it was one of the o rings on the fuel pump. lubricate the o rings with vasaline before installing

I replaced fuel pump and fuel filter but car still wont start. it will only crank if i keep putting starting fluid in it. what would be the problem?

bad fuel pump, loose wiring, blown fuse, or bad fuel pump relay. don't think just because a fuel pump is brand new out of the box it's good. i got an A/C delco fuel pump, installed it in the customers truck tried to start it .... nothing. checked all wiring, grounds, fuse, relay etc. everything was good. pulled the pump back out of the tank and wired it direct to a battery and it did nothing. got another pump installed worked just fine.

2000 discovery no start after new battery/alternator installed

Start with the fuel cutoff......sometimes they need to be reset. Step 2 would be the the fuel relay.........I doubt that the fuel pump is not working as you said you can hear it engage. Let me know if you need anymore help.
