If the pump's from a 406, they, (at least the later ones), have some electronic gizmos and an ecu - though whether that's integral with the pump.or elsewhere, I don't know. (Someone else may be able to explain better).

The conversion you've done, or Bosch pump onto 2.1 TD, (which we all thought you meant), is fairly common, but most people use an older spec Bosch pump, from a 405, or early Xantia.

Do you know if the stop solenoid's working, have you got fuel at the injectors?

You'll need to move the pump up/down to get the timing right, its trial and error unfortuanately.

"Understeer" is when you hit the fence with the front of the car.
"Oversteer" is when you hit the fence with the rear of the car.
"Horsepower" is how fast you hit the fence.
"Torque" is how far you take the fence with you.

If it is, and the IP is non ecu controlled, then loosening the bolts on pump and moving it up/down changes the timing.

You need to get it so engine starts, then slightly loosen bolts and move it and listen to get the right timing, engine noise should tell you when its right.

Immobiliser, you might have to put a live/ignition live 12v feed to the stop solenoid.

According to this http://www.vegetableoildiesel.co.uk/for ... p?tid=3233 it's the one in the blue circle. Looks like another useful thread to read (apart from the bit where he knackers his engine... )
