Hello and welcome to JustAnswer!
I’m sorry to hear you’re having an issue with your truck after all that work!
It sounds like maybe the crank sensor wires or the distributor wires may have got pinched in between the transmission bell housing and engine and now is shorting the 5 volt supply circuit which will cause this. Can you visually inspect the top section of the bell housing to see if the wires got pinched in between the transmission and engine?
Let me know and we’ll take it from here.
Thank you,
Richard

You don’t think it’s in security do you ?Security mode\*

No I don't think it's related to the security system. I have seen this problem before after engine swaps. It's very easy to get those wires pinched because they are on top and hard to see if your're not looking out for that.
My goal is to provide you with excellent service. If you're satisfied with my assistance, your 5-star rating at this time is appreciated. If you have any further questions feel free to ask!
Thank you,

I don’t even hear the fuel pump when I turn the key

Yes and you won't if those wires are pinched, cut and the 5 volt supply is shorted to ground. When the 5 volt supply gets shorted to ground, it takes down the PCM and you won't have gauges, the fuel pump won't energize and etc.

OkayEven if it the crank sensor is bad it’ll cause all those problems

Yes, if the crank sensor is damaged and shorted internally or the wires are cut and shorted to ground it will take down the 5 volt supply and PCM will be unresponsive.

Can you tell me what p1491 for the radiator fan circuit relay is

That code usually sets when the condenser fan fuse blows, it's fuse #39. I would check this fuse and see if it's burnt.
Still not sure what you need?
Have a certified mobile mechanic diagnose what's wrong with your car, at your home or office.
