Really need more info. When it is cold, you say it runs fine then quits. How long does it run? It starts, but starts hard meaning what? Cranks hard, or starts but runs rough? Do you have throttle body, or port injection? You could have dirty, or plugged injectors, or a blockage in the fuel rail. Got any codes? Get it scanned at a parts store, and they will tell you what the problem is, not charge you, and sell you the parts you might need. Mickey-d
