Truck not moving

There could be a couple of things that caused this, but we need to start with checking for codes and finding out what is there.

Here is a guide that will help with this:

Depending on what we find we may go in a different direction, but I suspect we are going to have to also check for proper fluid level and make sure it is not low and in good condition.

Once we run through this info and get the codes and fluid, we will have a better idea what the issue could be, but I suspect we will have a good idea what the issue is once we get this info.

Okay. Couple things. First, if the check engine light did come on then there was a code. It may not be on right now, but we still need to check for codes.

Also, I assumed when you said it will not go into gear, which means you put it into gear with the shifter, but it will not move the vehicle and it acts like it is in neutral in all gears.

Or did you mean the shifter will not move when the truck is running but when the key is in the on position, but the engine is not running then the shifter will move?

Let's clarify this and see if we can get the codes and go from there.

Okay. Just to be sure I understand, if when you put it in any gear it acts like it is in neutral and just revs then this is due to a lack of fluid or pressure.

So, we need to check the fluid and then check the pressure using the info below.

Unfortunately, this is most likely not a sensor. More than likely this is a pump issue.

This is most likely due to a fuel pressure issue from a failed pump, or the torque converter has failed.

Basically, we need to use the info I attached before and check the pressure in the unit and find out if we have the proper pressure and go from there.

Without this info then it is unlikely that we will figure this out just because we need to start running through the basics and that will take us to the next step.
