Technical Scudo 1.9TD, 90HP, camper engine replacement - new engine type

[Flemming DK]

Hello Fiatforum.

I have a 1997 Scudo 1, 1.9TD that wont start.
I am thinking the Dieselpump, as it doesnt feed the injectoors with Diesel.
I cant put on a tester, så sorry I have no faultcodes.
The startcode system has been interrupted, so you dont need the code to start.

I have several plans in my mind.

In Denmark there is this rule, that you need a partikelfilter on your old diesel car- But for the 1.9TD the option for putting on a filter, is not present.

1 plan is to get another engine 1.9TD, and put it in.

So Is it possible to put in a 1.6HDI, if you bring engine and harness from a donor car? eg a Scudo from no later than 2007 for instance?
(I know the HDI has the 90HP)
Or find Fiats own 1.6 diesel engine, again find it in a Scudo for instance no later than 2007

I know you can get a partikelfilter for the HDI engine.

I hope someone can guide me- even it is a long shot, on an old banger....

Thank you in advance.

Re the particle filter, on an 05 Fiat Doblo 1.9 JTD it had a particle filter which was basically a strainer with no electrical sensors or plugs so not like a modern DPF filter that needs a ECU computer to function. It was fitted at the front end of the exhaust just after the down pipe. If your danish regulations would permit that it would be much easier to install.
As your vehicle I ssume is pre any ECU computers sytsems , trying to fit the later engines with their ecu would be a nightmare .
It would be easier to get a later model van that complied with the regulations and convert it to a motorhome using your existing equipment I would have thought.
Another thing is , is your Fiat 1.9TD a Fiat engine or a Peugeot engine as they were both used.
Re any advice about your diesel pump it would help to see a photo of it and the engine , also try and let us know the Engine Series Number to get a better idea.

Thank you for your Quick and in depth answer, Im sorry I reply so late, but my mental load has been over the top for an extended period, with work and renovating my house.

Im sorry I am not aware of where to find my engine number, but my engine looks similar to the one on the picture.

Battery has since it died in Swizerland, been disconnected.

Second image is the fuelpump on my 1.9TD engine.
There is 12.4 volt on the purple wire.
I have tried loosening the nuts on the injectors, and no fuel comes to show, even while cranking.

The keypad is unplugged, and the car has been running without it since I got it.
I am not even sure I have the right combination for it.
A friend of mine told me there were a generic code used by mechanics, but he also could not remember it.

If it is any help my VIN is ZFA22000012194674

Thank you in advance

Sorry I cannot see a number I recognise on the chassis/vin plate re engine series.
I think it is a Peugeot engine possible of the XUD series possibly 1905cc maybe used in Peugeot 405 cars?
Re the injector pump, in your photo behind the accelerator wire is what looks like black sealant with several wires coming out to the junction plug and look like they have been rejoined by someone.
I suspect behind that black sealant is a solenoid with a single wire going to it.
If that is the case then normally if working and you apply 12 volts to it , then it should activate the fuel cut off solenoid on the Bosch injector pump allowing fuel to go into pump to start the engine after bleeding air out of course if required.
In the older versions they just had the single wire going to that solenoid, then to "anti theft" the vehicle they fitted a security shield over that end of the pump and had several wires going to it from an early form of "immobiliser", later vehicles with computers were much more sophisticated.
If you look at various photos on the internet of that type of pump you may see what I mean about the solenoid valve that stops the fuel, it is roughly just above the four fuel injector pipes coming from the injector pump.
If that is your injector pump in the second photo , then I think the dip stick to me points to it being a Peugeot engine.

I have been tampering with those wires, in order to measure voltage.
No its not nicely done

There once were a sticker on the pump, ofc it fell off when I washed down the engine some 2 years ago, after I did replace the timingbelt.
It has been driving for more than 3000km (1900miles) after I replaced the timingbelt.

Ive read somewhere about this tamperproof pump, and its solenoid, on a peugeot forum- and no its totally gone in my memory where, or even how I found it.
But yes this engine is in several peugeots - from that time.

I have tried to find the engine number without any Luck, as it should be just behind the pump- visible from the front.

I have found a workshop manual, containing the wiring harness, but it doesnt say whats in the black box behind the pump, containing the stop solenoid.

Ill have another go tomorrow, and even see if I can find the page describing that pump.

Thank you for your efford and answer- ill keep you posted on my progress.

What I expect you will find behind all the go is this, or similar below in photo.
On the original pumps it was just as below with a 12 volt supply when ignition turned on to allow fuel to flow through injector pump, they later used multiple wires and a circuit board as a form of basic immobiliser hidden behind a metal cover held on with security bolts, but it still used that solenoid.
I did have a customer many years ago with a Peugeot 305 with the basic solenoid that had failed, he was firm that he had to use the vehicle so I removed the spring loaded valve inside the solenoid until a new one arrived. This allowed him to start and use the car, but it meant he had to stall it when he wanted to turn it off, so not a good idea, however I soon fitted the new solenoid.
