Truck wont start engine turning over, low fuel, sounds like it is starving for fuel?

Hello, If you have a battery charger, throw them on charge overnight. No more than a 3amp trickle charge. If you can charge one battery, and you can jump the truck by hooking the other battery to jumper cables, then you have identified the problem as low/dead batteries.

And yes, PSD's make a lot of noise on start up. A difference you will notice between the cumming and the psd engine at start-up is that the psd cranks longer. This is due to the fact that the fuel injectors on the psd are actuated by oil pressure.

Thanks
