Tldr car sat un-powered for 2 years while engine and transmission was being rebuilt, put everything back together and hooked up with new battery no crank no start.

Details.
I don't think it's the PATS system as thr security light goes off and stays off once key is in and car is on. And I can unlock and lock car with keyfob,

I verified and jumped the ignition wires blue and red to blue and white. ( no start /no crank )
I checked power to blue and white when key is on the starting position. ( I'm getting power),

All fuses and relays are good.
Pcm is good as it does the throttle body sweep and you can hear other modules triggering, I've also verified power on thr 2 main pins, pins 4 and 3 and 5.

All grounds are solid and strong.

Starter is getting 12+V
signal wire is dead when trying to start
Jumping main power to signal wire causes the car to crank but not start.

Fuel pump is coming on. And building pressure at injectors. ( have not pulled injector rail to see if these are actually activating )

When key is on but not cranking CEL flashes about 8/9 times and stays solid ( engine was rebuilt due to cylinder 2 dropping to sub 15psi.

Welcome to the FFO!

You might pull codes. That is why the CEL is flashing.

The control circuit from the ignition switch passes from there to .... (from memory)
Through a fuse
Transmission range switch
To a relay

Its still retaining old codes from before the rebuild even when cleared.

It has 2 new codes P0706 and p0708 for high range transmission range. Would this be the cause of no crank/no start?
So then i tried manually put the transmission through all gears and attempting to start with no luck of cranking or starting.

I checked and bypassed the fuses for testing and all gave same result of no start.

If the transmission range sensor is bad, you can clear codes and those codes will come back.
If the transmission range sensor is bad, the engine may not crank. If you want to verify that, at the range sensor the two wires that go in based on diagram, Key on, transmission in park, there should be 12v+ on both wires. In a drive gear or reverse there will be 12v+ only on one wire.

Any other codes?'

You sure ignition is the issue? Spray in some carb cleaner and does the engine fire up in any way?

Only 3 codes. P301, p302, p300 but these were there before the rebuild

I've tested coil packs and they ohm out at .000, and when plugged into thr harness and test light plugged into coil Pack when starting it gets no light pulses. And then I tried with coilpack and plug out. No spark on the plugs either
Or am I testing this wrong?

Fuel pressure is strong and solid, fuel injectors are spraying.

Those are generic misfire codes that could be fuel or ignition.
Should clear them.

Wiring diagram from the net.
The note is wrong as the voltage of the electronic engine systems is 5 volts.
Key on engine off is there voltage on one side of the coil?
If no is the PCM relay clicking on?
If no is there power to the battery junction box?

The voltage is good.
These are ground side switched.
Meaning the coil will generate the spark when the ground side is grounded completing the circuit.

The trigger for that is the PCM.
And the PCM makes that happen by getting signals from sensors.
Cam and/or crank sensors for the most part. To a smaller degree the throttle position sensor

What OHM should cam sensor be?

I do not know. I think the resistance varies.
Should be 5 volts in and likely variable out as the sensor moves with the cam/crank.

That is good. That 5v is from the PCM. Also called reference voltage.
The wire back to the PCM modifies that 5 volts to a lower amount as the engine cranks.

If there is a 3rd wire that is ground.

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.

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
