Engine No Start

Hi,

My vehicle will no longer start. It occasionally stumbled or hesitated in first and second, but then recently on my way home it would not rev over 3000 rpm's. The next morning it started but ran rough. Fiddled with a few things and now it no longer starts. There was an occasional sound that was not relative to engine speed and I could not repeat it. It sounded like a big washer spinning and clinking on the prop shaft and it was from somewhere in the engine.

The following was tried:
Injector cleaner added to tank. Mostly drained and replaced with clean fuel.
Cleaned throttle body and checked MAP sensor against known specifications.
Checked crank position sensor, tested fine, but replaced it anyway.
Removed and cleaned injectors with carburetor cleaner attached to tubes; actuating with battery. A lot of grit came out of two.
Check camshaft position sensor. It tested way off and replaced it.
New plugs.
Checked spark on both coils.
Did not check fuel pressure, but plenty spray when I release the hose and plugs wet.
Removed and cleaned fuel pressure unit.
Checked cam belt timing, all good.
Took compression readings with “modified” tester (sparkplug with tube to reach deep enough)
Psi Readings Cylinder :
1. 90
2.90
3.105
4.90
No wet compression test done.

No oil leaks, no smoke, immediate cold start and perfect idle. No engine light.

Receiving scanner tomorrow to check for any codes.

When attempting to start with a freshly charged battery it does not even try. Just a bit of a boof boof here and there that sounds way off the mark.
Thanks
