Morning all, just wondering if anyone can help? I've just swapped my injection pump with used one off fleabay and I have no power! Very sluggish its like driving a 2.5 na! Its almost like the turbo isn't boosting properly. Apparently the pump is standard with no tweaks. Before I tweak it I was wondering if I've left a pipe off or something simple. Any help would be appreciated.

Cheers

check bajo at rear has a little hole ,clean airless fuel to front banjo ,timed up correctly ,some need a smaller pin used and pum turned clockwise on big nut against it with 3 flange bolts slackened ,boost feed from turbo fitted ,plus theres a fair chance pump is worn/faulty
 
Thanks for the advice. I'm going to have a play tomorrow! Will check timing first and work back from there! Thanks again
 
Checked timing and it's spot on. Tried to advance timing alittle using 8mm drill bit to see if it made a difference in power but I can't turn it to the right it seems to be on maximum adjustment! Is there a way of adjusting this? Cheers all!
 
not with out slackening belt and moving pulley a tooth its a common mistake not to ensure belts fitted with ample adjust ment ,wedging belt on cam and crank pulley with some non damaging material helps ,but obviously requires front cover off,has it got good airless fuel supply to front banjo on pump
 
Thought I might have to take belt off again! Im getting quicker each time! Cracked off banjo and got covered in fuel! So I take it from that is got a good fuel supply! Forgot to mention I also changed fuel lift pump at the same time as injection pump. So I'll strip it all down again and move the pulley a tooth or two.

Many thanks again for your help

Removed cambelt and adjusted pump pulley a couple of cogs. Got the adjustment I wanted but still down on power. Engine just gets louder using 8mm timing pin and really growls with 6mm!

Do you you think the pump needs a little tweak as there is no smoke at all even when hammering it?


Cheers
 
I've tried advancing and retarding timing to see if there's a difference and seems to make no difference just engine noise.

Think I might check the hoses to see if there is any leaks. Will sort this if it kills me!
 
does it look like anybody has unscrewed the top cover off the pump and is the tamperproof plug still on the top of the pump? if the tamperproof plug is still fitted check it to see if you can see any screwdriver marks or signs of being removed
 
Update!
Set timing back to standard with 10mm pin. Tweaked pump by turning starwheel in by 1 turn. 1 full turn in on the smoke screw. Now it's pretty good! Minimal smoke also!
