First thing I would suggest is getting it towed home or to a shop, then pulling the regulator/fca to see if it’s full of metal. If so, it’s time to dove into the fuel system because of a cp4 failure

Your truck doesn’t have a ficm, it’s controlled by the ecm on your truck

That explains why I couldn't find it haha. I read some people have had this problem with aftermarket fuel filters. I currently have a wix filter on and it's past due to be changed so I'm trying that tomorrow. After that I'm calling the mechanic because I don't have the skills for that.

If the primer bulb is hard then it’s not lack of fuel because of the filter. It likely wouldn’t have a hard primer if it was the filter. It’s unusual to have an air leak between the filter head and injection pump

Pump it, crank it, pump it, crank it, pump it, crank it. Being an LML might have to pinch the return line to give it some back pressure to start. I’m still thinking it’s a failure and you don’t really know until you find the metal in the system

Rob is right, more than just a conversion… although if it is done THOROUGHLY, the tank can be cleaned and probably a new sending unit to replace the pickup and level sensor

That’s why I emphasized THOROUGHLY
And Lincoln Diesel has a pretty good catastrophic failure kit put together. I may be ordering one pretty soon for a customer of mine, we will see
