Stalling when accelerating on an incline

Hi Chris,

We need to check a couple things. The only thing that cares or really knows that you are on a hill are the fluids in the vehicle.

So depending on what type of trouble you are having will dictate what fluid this could be. If it is just stalling or stumbling then I suspect you may have a fuel pump issue. Hook a pressure gauge to the rail and see if your pressure is dropping when on a hill.

Number 3 on this guide will show you how to do this but your pressure should remain constant +/- a couple PSI.

If it feels like it is going into neutral on a hill this is most likely the transmission fluid.

Let me know what the pressure is and we can go from there. Thanks
