My friend has a 2005 ssang musso dual cab ,and has just changed a motor (SH low kms) after it blew up .....big dramas. He has just rung me to see if I know how to bleed the injector pump.
There are no instructions ,seems to be an inline pump, no plungers on filter,or side of pump. Have tied to wind over eng and crack injectors, fuel is getting to pump (when delivery pipe is cracked). They did'nt sound very happy after a nightmare engine changeover!

Those motors normaly self bleed, ie if you run them out of fuel they normaly will fire up once fuel is added. I would be looking at the pump control, is it the mechanical or electronic model? Eric.

Thanks for reply . I hadn't rhought of that.
Maybe a plug isnt connected or pushed in properly. Normally you can hear some movement when key is turned on.
I will keep you posted. Regards,David.

I now fill the filter before I put it on and hit the hand primer, on top of the filter housing, till it goes real hard..... works every time
Does the Musso have this arrangement ?

I used to remove the after the filter line, put a length of clear hose on it and gently suck fuel through, and spit for an hour or so afterwards..Yuk !

From what I can gather, dramas started with blown hole in EGR
valve ,exhast gases melted vacume pipe for brakes. Replaced EGR valve .
Not long after, head gasket blew out ,lost all fluid ,and cooked eng.
Had trouble getting parts ,so went for exchange SH motor.
I think the real dramas started when they were trying to get the old eng out , and the new one in !(very squeezy ).

RE fuel problems : I have checked solinoid on fuel supply and it seems to click in and out.(still am suspicious about its operation,but cant remove it to check properly)
Lift pump is working on side of injector pump.
Have expelled all air from filter ,right to pump.
On winding eng over ,and cracking pipes at pump, only a little fuel and air come from 3,4, and 5 pipes.None from 1 and 2.
I didn't think inline pumps would bleed on their own ?
Absolutely no sign of bleed screws.
Monday ,they will get more info from dealer.
Thanks for all the suggestions .

The model is a 290 S (Sportsman? ) 2006

I would try removing the glow plugs and turning it over on the starter.
When you see 5 plumes of diesel being pumped out the glowplug holes,its ready to replace the glow plugs.

The engine will spin at almost idling speed with no compression and draw fuel through quickly

Some engines are recommended to be bled this way including Landcruisers
