Acceleration failure and chokes

Nissan Frontier 2006  165937 miles
I own a Frontier diesel 2006 and the failure it has is that it takes long to start working. I have to try for at least four times and, once it starts, I want to speed up but it won't accelerate. It chokes and only reaches 1100 rpm, not more. I've already changed the crankshaft's sensor, potentiometer, fuel relevator, fuel filters and the temperature sensor but it is still the same. What else might it be?

Hi buddy, I have a Nissan Frontier diessel 3.2 engine zd30 and some time ago I had your same problem. The failure was in the injection pump's switch or connector, which was isolated. As you might see the solution was finally an easy one. You should as well check the spark plugs. Hope my comments help you!
