Was driving the other day and it just died and wouldn't start back up. It has fire and is getting gas. Any help would be helpful it's a 4.0 Sohc

 

Welcome to the forum!

When you say "it has fire" do you mean that you confirmed there is spark at a spark plug wire?

Did you just confirm that fuel sprays from the pressure valve when depressed, or did you actually install a gauge and confirm the fuel pressure is where it should be?

Was the truck driving fine up to the point that it stalled?

Have you checked under the hood for any disconnected lines, such as the intake air tubing between the air filter and the throttle body?

Has any service been performed recently that would have had someone under the hood?

Did you try holding the accelerator pedal all the way to the floor when engaging the starter in case the cylinders were flooded?

Yes pulled a spark out and it was firing and the fuel pressure is rite. It was running fine down the road and just died. The motor sounds like it's cranking fast

 

Cranking fast would suggest low compression, possibly due to damage of the timing chain system.

My next suggestion would be to check compression (which is also needed for an engine to start).
