Good morning.
The most common failure for no fuel is the fuel pump. A fuel pressure test will confirm. You need to test the pressure at the test port on the fuel rail. If you do not have a tester, you can rent one at a parts store.
As far as the Map sensor light, what code is set for you to think this is a issue?
