Mitsubishi Pajero - fueling issue
#1
Not an XUD as such but a diesel nonetheless. 

If anyone has one or knows there way around this it would be appreciated.

Symptoms; when cold, idle is low, no power, seems like fuel starvation, wont rev properly etc, especially on hills

Tried cures; fuel filter changed, air filter changed, checked the EGR (which has somehow created a whole, solid carbon block post-valve, quite incredible. Will get a pic), de-EGR'd. 

I think it maybe a cold idle issue. As it warms up, the idle raises and the power comes back as normal, but takes 5 minutes to warm up.

Any DERV heads got any ideas would be appreciated.

do these have a fuel pickup gauze on the pickup pipe in the tank like the 306s?

This sounds like the injector pump, have you had the seal replaced on the injector pump? We own a Pajero and had lots of problems but it now runs perfect

I believe so; the pickup and filter was cleaned and changed

Is it a tough job, I've only looked quickly at the fuel pump, does it need timing again or is not mechanical pump?

These symptoms are 100% fuel pump seals.

I have owned a few of these and I am afraid that is the only explanation for what is going on.

Try a search on POCUK.COM for your problem and I guarantee you will come to this conclusion.

You have to take the pump out, There's a guy not far from me who does them in a couple of hours. He's done 100s of them, His website is www.mobilemechanic.org

Maybe get an IPP gauge on the pump to see whats going on with pressure? It could highlight an air leak pre-pump that only goes away as the diesel is heated/less viscous

It just is pump seals. No messing about. Owned a few and all symptoms are there.

Gets to the point it cuts out on corners and hills.

Looks like new fuel pump then! Hard to come by
