Got no fire and am going to troubleshoot ignition system. I want to disable the fuel pump so that I won't flood it while turning the engine over. I read an old thread here that said "pull this fuse" but the thread is from 2004 and the picture is gone. My fuse box has a fuse that says "engine 20A" Is this the fuse? No fuel pump fuse in my fuse box. I don't want to pull the engine fuse and disable the ignition by doing so.
Or do any of the fusable links disconnect the fuel pump without affecting the ignition ?
I know that I can remove the driver's luggage compartment and unplug the pump, but didn't want to do this if I could just pull a fuse or a link and disconnect it.
Thanks for your help for an issue that is probably stupid for most of the experienced guys here.

For what you're doing, which is a more protracted disconnection of the fuel pump to prevent flooding while you crank the engine, pulling out your DS storage bin and disconnecting the pump at the plug is the best method. Anything else (Engine 20A fuse) is just fooling the ECU into not firing the Injectors based on the Trailing Coil trigger. In other words, your fuel pump will still be flowing when air is coming in the Air Flow Meter, it just won't be injecting fuel. If you have a bad or leaky Injector, it still won't prevent flooding, because the pump is still providing pressure.

Long story short, just disconnect the Fuel Pump plug, for safety sake. You don't want any fuel vapor in the vicinity while troubleshooting ignition components.

Thanks LongDuck, I'll disconnect the leads to the fuel pump.

For reference, the connector for the fuel pump has a white body and is a two pin connector. You will spot it easily as there's a grommet in the floor where the wiring comes through and connects inside of the car.
