Hello, I am new to the forums but was wondering if anyone had the same problem as I have been having with my 1995 Ford F350 diesel truck.

My father and I recently put in a new motor, changed the fuel pump, changed the fuel selector and now the engine will turn over and sit idle but when we go to actually run it the fuel filter goes dry to the point that there is no diesel reaching it.

We changed out the motor since it had actually died on us and the new motor is used but still has a week under warranty in case we need to return it.

But yea the engine turns over till we try to drive it could it be the motor? Or could we have screwed up somewhere else. . .

Any help is appreciated.

I posted this in another area by mistake. . . but thanks for any help.

sounds like the pump. When you changed the pump did you make the "tappet" was on the end?
You tried both tanks already....sounds like the pump to me

 

The Fuel pump was done by a independent garage near my house, but it worked fine for the other engine. We started having trouble with it not going into gear once we changed out the fuel selector, LAzy K suggested that the fuel lift pump might be sucking in air.

As for the tappet I am not sure what that is. . .

 

Have you checked fuel pressure at idle?

 

My dad went over to the shop to check that today, I read it in a separate thread and thought it might be a good idea. Any idea as to what may be the problem if the pressure is to low or too high though?
