I have a 2000 saturn, I just replaced fuel pump and the car ran fine for a couple of days. Then one morning it just wouldn't stat running, it starts for a couple of seconds then dies. I have fuel pressure all the way to the valve on the fuel rail. Could it be injector problems or catalytic converter cloged?

Replacing the Ignition Control Module, AutoZone Part Number SA102, $106.99, will likely solve the problem. Disconnect the negative battery cable, prior to beginning work.
