My QX4 won't start. It cranks and the starter is working. Thought it was the fuel pump so I replaced it. I can hear it spin but when I try to start it, it still will not turn over. What could it be?

What is your question?

Check engine light cane on before this happened. The code cane back as P1130 and P403. "Faulty hose near the swirl control valve". Removed 3 hoses, blew air in and replaced hoses back on. Car ran fine. 2 days later, it cranks from the starter but will not turn over.
