Hi Anthony,

Can you determine if fuel is being sent to the injectors? Is this Disco a diesel or petrol?  What model and what year?

Answer
Hi Anthony,

here's what you do:

double-check the fuel pump installation.  Next, check for loose or faulty electrical connections in the ignition circuit.

Check all the vacuum hoses for any leaks.  Next, check the fuel lines to make sure there's no kinks. Naturally, replace the fuel filter (it goes on only one way!).

Lastly, check the fuse boxes for ANY blown fuses.  One blown fuse can cause this problem.

Best of luck,
