If the PCM thinks the engine is not cranking (no signal from cam sensor) it will not fire off either.
The PCM is very specific on when to squirt and fire. (That was not the case in early fuel injection .... think 1980s)
The PCM will need to know when each cylinder comes up for compression for fuel and ignition to work.

Engine not spinning? No fuel and ignition events.
You know the engine is cranking. The PCM does not, without signals from cam and/or crank.

I'll double check the cam sensor. Will also pull cover off to verify cams are moving

. Crank sensor is working as the obd2 scanner is pulling RPM of 250-300.
Shows ignition advance timing for CYL is at 10° when trying to crank.

Alright got around to checking cam sensor

KOEO on the cam sensor.
Purple and green wire has 12v
Purple and blue wire has 0.08 V.(installed
)
Purple and blue wire has. 0.00v ( not installed /still hooked up to wiring harness
)

Purple and blue wire has 12v when making contact with metal(
)

Green wire is ground
 
Follow the testing in the link in post #18.
Scroll down to the 3 wire sensor.
You will need a second person.

All that checked out fine and within ranges.

Pulled valve cover off. Notice the top side of cam chain was loose as crap.

Pulling timing cover off setting TDC and resetting time.

Will update when completed with results!

Thank you much everyone who assisted! Will see you in few days with some updates

Alrighty. I got done fighting idk what. It kept me in bed longer than expected.

In the mean time I was speaking to one of my buddies who rebuilt one of these before and said there was a certain way I had to set timing that involved setting a pin somewhere, and spinning engine till it stopped and then setting cams and all in time using the cam tool etc.

But I tried searching everywhere for this timing guide. With no luck. Do you happen to have this somewhere by chance?

Everywhere I look or see. Just says set TDC on Cyl 1 and set the cams lock the bar in it make slight adjustment to Cams if need be to have the chain lock in place.
 
I have none of that as I do not have the factory shop manual for 2009.
I do have factory shop manual for my 2006 Lincoln Navigator (and Ford Explorer)
Yes there is a specific way to "Time" the engine with the cams, chains and gears/phasers.

This may help assuming you have a Duratec 4 cylinder

Haven't forgotten about this haha

Engine was reset to TDC, retimed, chains check and tight. Everything looks to be setup correctly.

Checked the crank sensor and got one on the way just incase. It's reading .447 ohms with very very minimal movement maybe 0.0xx at most even when metal moves across it.

After all this time. I had the crank sensor on backwards and the field wasn't lining up with the timing marks on the crank pulley 🤣🤣🤣🤣

best part is. The moment it got fired up and ran. It snapped a valve off in half so now I gotta tear it back apart and see what happened because I turned it over countless times before hand and everything was smooth and in line how it should of been
