Is there a way to tell if a fuel pump is going bad?
The subject says it all. Im 99% sure my injectors are bad, and i figured with 92,000 miles the fuel pump might be going too.

Some make noise before they die, mine didn't. I went out to start it one morning and it didn't work. There was no other warning. The only way to really know is to put a fuel pressure guage in the car and see if it holds pressure at WOT.

You can tell when your car feels like its running out of gas but you have plenty of it in the tank.
And then when you have the key to the on position before you start the motor you should hear the pump prime. And you can push on the valve stem of the shrader (sp?) valve on the fuel rail and it should squirt alot of gas.
