i have a 2007 astra diesel 1.7 dth which is getting no fuel at the injectors. i bought the vehicle half stripped due to it overheating but was running fine before this. i rebuilt with new parts but now no fuel at the injectors.

when doing the pump timing does it make a difference if the woodruff key is pointing up or down and would this make a difference anyway? the pump pulley has 2 holes in which would both line up with timing hole.

there are no fault codes stored. i have tried by squirting a bit of brake cleaner into air intake ( i know its not ideal ) and engine ran fine for a few seconds so im pretty sure it is just the fuel problem, any ideas ?

wasthinking about just running some fuel direct into the top of the pump , would this work ?
