i have a vw caddy 1.9 sdi am having a problem with the diesel pump the prob is there seems to be no fuel coming out of the injection side of the pump. the fuel is getting into the pump just not coming out the other side. i have checked that all the timing is at tdc. and had the pump tested. i have been told that the pump is in fine working order which confuses me even more. i do hope you will be able to help me thankyou

im no diesel mechanic,but i have a p,up.try this...take out the top return line on the pump,fill it completly full of fuel.(it has a 17mm(?)head,2 lines,one running tothe first inj.(small) the other back to the tank (large).if you replaced the pump or had 1 or all the lines off ,itsmore than likly air locked .hope this helped!!!(youll more than likly have to bleed the inj,also)be sure not to lose the copper gasket under the plug&retighten the plug securly.yours truly,nddunc
