Sorry cannot see video. Welcome to FTE anyhow! We'll help you figure this out.

Are the new sensors all OE Ford or IH? Asking since some aftermarket parts are not so good.

So it takes a long time to start, but it does start? Or just no start?

How is the fuel and oil level?

Injector O-rings are a possibility there, search and apply the Cody Test to check that one.

Just to follow up with Walleye Hunter suggested, you may find some assistance in the Tech Folder linked below.

Also, the "Cody Test" refers to an injector O-ring test which details can be found by searching and the link below.

There's also been cases of low battery voltage or even the started pulling to much current, bad started, and not letting it start.
