Outer Limits 4x4 Board

hi there just in the process of putting a 2001 GU 4.2td in my to my 4.8gu my problem is im wiring up the soliniod but it does not seem to work there are three wire brown blue and black but no combination seems to work is there any way you can pull it off the back of the injector pump with out removing the pump as to have it replace

have tried to remove but have no idea how or what tool is needed to remove it as i cant see and every tool ive tried dont undo it so HELP any info on how to wire it and how to remove it would be great

gudday

It CAN be done in place, i had to do it when a turbo timer malfuctioned and damaged mine.

I'm assuming the pump is the same as a 96 TD42T zexel unit. Its the lower soleniod. After removing and brackets and pipe work around the shutdown/run sol i cut down a spanner and got it out carefully without droping out the plunger and spring underneith or getting grit inside.

They can be on very tight!

PS: before pulling it out i assume you have put 12V directly on it to check it?

good luck
