Quick update after finally getting back on my feet.
Checked the spark and turns out there no spark produced. Bought a crankshaft position sensor and replaced it but still crank and no start.

So far, fuel pump and delivery ok, air is not restricted and ok, but no spark and CPS is not it. No codes. What do you suggest to look at next? This is puzzling.
