Daewoo 2000 Lanos. Car will start then moments later it will die. When it's started I can push down on the gas pedal and it will rev up, but if I push too far down on gas pedal it will immediately die. It will run fine with engine starter fluid. Makes me think something to do with fuel. I can hear the Fuel Pump turn on. I've changed the Fuel Filter under the hood, Idle Control Valve, and Throttle Positioning Sensor. I'm now thinking maybe it's the Fuel Pump, Fuel Injector(s), Computer, I need advice before I go out and spend more money. I bought a ODB II code reader. Originally I was getting the P0120 code, but then I replaced the Throttle Positioning. Now no codes, perhaps I cleared the code by accident or the issue was resolved. Any advice of what my problem may be would be appreciated, thank you.
Yea if it runs on start fluid then your not getting enough fuel .. you are likley going to have to change out that fuel pump .. you might hear it come on but it might not be pumping fluid forward .. good luck

possible blocked fuel filter or fuel pump not supplying enough fuel (starving) check fuel pressure with pressure gauge
also blocked exhaust or cataletic convertor can cause same issue
CHECK THE IDLE SPEED SENSOR, UNPLUG IT AND SEE IF THE VEHICLE REVS UP A BIT. IF IT DOES, THEN REPLACE IT. ALSO CHECK THE FUEL PUMP RELAY IN THE FUSEBOX. HOPE THIS HELPS. .LET ME KNOW. GOOD LUCK
