Bring a large pot of water to a boil. Add about 1/2 tablespoon of salt and the fettuccine. Cook according to package directions. Reserve about 1/2 cup of cooking liquid just before draining.
Heat oil over medium-high heat in a large pan.
Season shrimp and scallops with salt and pepper and cook in the oil for 1 to 2 minutes per side. Remove from pan and set aside.
Add butter to the pan (no need to wipe it clean). Turn heat to medium, add onion and cook for 3 minutes.
Add garlic and cook 1 more minute.
Sprinkle flour into pan. Cook and stir for 1 minute.
Gradually whisk in half-and-half. Cook and stir until thickened.
Add red pepper flakes, black pepper, sugar, and sherry.
Add crab meat, peas, pimentos and Parmesan cheese. Turn heat to low and stir until cheese is melted. If sauce is too thick, add some of the reserved cooking liquid. Check for seasoning and add salt to taste.
