2001 Daewoo lanos check engine light is on Car does not start but if I spray starting fuild into air intake it will start but does not run well and the check engine light is on.?

The check engine light being on indicates that there is a fault with the engine management system, which could be due to issues like a faulty fuel pump, clogged fuel filter, or a malfunctioning sensor. Since the car starts with starting fluid, it suggests that fuel delivery is likely the problem. You should check for fuel pressure, inspect the fuel pump and filter, and also scan the vehicle for diagnostic trouble codes to pinpoint the exact issue. Addressing the fuel system components should help resolve the starting problem and the check engine light.
