engine change non starter

morning people just changed my engine in my 98 l diesel afer the old one let go like a firework but can any one tell me if the fuel pumps are coded to the car as i dont have fuel coming out of the injection pipes from new/old engine want to make sure before i go putting the old pump.

The VP37 its not coded to the car.

cheers guess ill be putting old one on and trying that

have you perhaps an airlock, is fuel present going into pump?

i believe so i have used the hand pump to prime system

is fuel getting to the pump?

Right thanks for the replys yes fuel was getting to the pump turns out the batter was duff so not turning it over quick enough all sorted so no need to change pump or anything. and I suppose as I been away a while suppose I had better do an update what I been up to so watch this space.
