Bad crank shaft sensor will make it do that, check it or replace it, it's located on lower front passenger side bolted to timing chain cover next to ur ac compressor

I have checked the crankshaft sensor and when I removed it, it had oil and dirt. It's that normal?

Well, there's many things than can cause it, one is the crankshaft positioning sensor, and the others that u mentioned also vacuum leaks or a dirty throttle body

The vehicle has no vacuum leaks and everything else are clean. Do you think it might be the fuel pump.

Check fuel pressure to see if it's ok. When was the last time u replaced fuel filter, if u haven't, u may want to do it as a routime maintenance anyway
