Default Fuel pump questions

I recently bought a 2001 Expert 1.9D. The seller warned me that it was hard to start and needed a new battery. I had a spare nearly new one in the shed so that was the first thing I did. It is still a so-and-so to start and in fact the only way to get it going first turn is to start by getting up some pressure by pumping the little manual bleed button under the bonnet. After doing that it is quite eager to start. Without doing that starting is a lost cause.
My question is, does this engine have a fuel lift pump? Where is it located? Is it electric or mechanical? When I get in and turn the key I can't hear any electric pump noise like I can when starting the wife's 406.

I quite like the van but I find it hard to understand how any company could sell such an underpowered commercial vehicle. Its slower than a slug in a freezer.

The pump is part of the injection system, that's why the priming bulb is there.
Most likely the priming bulb needs replacing, sounds like the non-return valve isn't working.
It's a workhorse, perhaps sparkling performance wasn't a top priority when it was designed.

The fuel system can leak back on these causing starting issue

This engine DOES need its glowplugs all working or its harder to start

This engine is VERY slow it has no turbo and is underpowered in the 206 never mind in a van !

Having said all that it is a relatively simple engine that can be very reliable if your not in a rush.

Thanks. That information will be useful. Given the symptoms, your suggestion of a faulty non-return valve makes a lot of sense. Now I am wondering if I can get at the valve to replace it without destroying the whole pump. I'm scared to death of opening up an injection pump. A replacement one here in France would cost more than the van did.

As long as I can avoid having to stand in the rain hitting the priming pump every morning it will suit my needs. Daily transport but usually empty so economy is king for me at the moment.

The non return valve is in the primer not the pump.

That's great news. If push comes to shove, I may be able to source a whole replacement unit.

I did mean the primer. Anything involving taking the injection pump apart should be left to a specialist.

If that is true I can solve the problem easily. I can get a new complete fuel filter housing which has the primer button included for under 25.

That may well be best bet as the push button type were prone to leaking
