Technical 1993 Ducato 1.9 TD wont start
Yes, there is an electric pump in the tank. You should hear it run for a second or so when the ignition is turned on. If not check fuses and relays first, could be just a bad connection.

Thank you for the info, I thought there must be a pump somewhere. I'm pretty sure that it is a bad connection somewhere. I have renewed all the connectors around the fuel filter but that did not fix it. I'll try and find the pump connections or relay if there is one. I can't see a fuse listed in the User Guide.
easy fix might be fill the fuel pump by hand just disconnect fuel pump from tank fill filter via same connection using plastic pipe inserted through hole p/pipe connected to a filler of some kind various ideas would work once once engine getting fuel and starts quickly reconnect fuel pipe and you may find the vacuum created by engine may clear fuel pump in tank if thats the problem
Should have mentioned this earlier, make sure you check and reset the inertia/crash fuel cut-off sensor. It's normally in the front left foot well somewhere, check the owners manual for exact location. They rarely give trouble but it's not unknown and it's a really easy check, just press on the rubber cover.

I'll check for the fuel cut off, the thing is the van was working perfectly when I returned from Weymouth earlier this year and it has just been parked in my garden since. I checked around the fuel tank and cannot see any connections for a fuel pump I'm not sure that there is a pump in the tank on this model. But I have no idea how fuel is pumped or drawn to the filter. Fuel does not seem to be reaching the filter.
Thanks for your help.
Thanks for your help.
As it's an earlier model it may have an inline pump, maybe along the chassis somewhere. There is a possibility that it does not have an electric pump. This leaves the option of a mechanical pump on the engine or it's possible the injection pump does not need a "lift" pump. If this is the case there would normally be a manual priming pump somewhere. This could be a knob you turn to unlock and them pump in and out or just a simple rubber bulb or button.
Thank you for your help and suggestions. I can't see a pump anywhere, I've always assumed that the injection pump somehow draws the fuel from the tank. I looked for the fuel cut off switch but there isn't one. I'm sure it must be an electrical fault, probably a corroded connector somewhere, but I've no idea where to look.
In these old lumps with no lift pump the pump has to vacuum it from the tank when its idle for a long time air leaks allow the fuel to drain back to the tank. Leaks are usually the rubber return hoses on the injectors perished or the primer bulb on the filter head if fitted.
If you're lucky the filter head will have a primer like this an if its intact you can prime by pumping that:

Thank you Corcai, I can't see anything like a primer on the filter or the injection pump. I have tried bypassing the filter but after lots of cranking no fuel appears to be drawn from the tank. It's as if the fuel cutoff when the engine is stopped is staying in the off position. Unfortunately I know very little about diesel engines all my experience is on petrol engines.
Hi,
There may be an electical shut-off solenoid on the mechanical injection pump. Check that it getting power and working OK (you should hear it click if you connect and disconnect it with the "ignition" key in the run position). A quick check can be to unscrew it and remove the plunger and spring before putting it back. If the engine then starts you will have to stall it to stop it.

have you filled the bulkhead fuel filter with fuel , and tried cranking again from there..
always worked with my old 1929 Tipo TD - no hand crank on that either.

if you had read my post of 1 week ago and followed my instructions on how to do this you may have been making progress by now not much point asking for help and info then not reading replies.
I'm very sorry you say that Jontee, I have been looking at the replies every day and I did try with a pipe straight from the high pressure pump into a container of diesel and cranked the engine until the battery went flat and it did not draw any fuel into the pump, I have not however tried to fill the filter and see if it will start like that. Perhaps a slight head of fuel from the filter might be enough to enable a syphoning type action from the tank to the injection pump, the filter being up at bonnet height. It seems very odd to me that there is not a fuel pump or a primer anywhere that I can find.
I find using "quote" or username,
helps them realise they've had a reply..,
if they revisit a week later , now with a dozen posts , it's easy to miss some detail..

I suspect if you can get it to cough and splutter on a bit of fuel from the filter body, ( yes - fill the cannister like a bucket..and carefully refit)
it'll get the revs up enough to draw fuel from the tank..,
good luck,
Charlie
Thanks Charlie, that's what I'm going to try next as soon as I can go and get some fuel.I suspect if you can get it to cough and splutter on a bit of fuel from the filter body, ( yes - fill the cannister like a bucket..and carefully refit)

Do you know what the electrical connections to the filter are for? I know the ones at the base is the water in fuel detector, but there are also two pairs of connections to the top section that the filter is connected to, I've no idea what they do.
