Dispatch/Jumpy wont start (SOLVED)

Hi there!

I have a MY2006 Jumpy with 2.0 HDi (DW10BTED+) engine. It wont start.
I've checked fault codes and the reader cannot connect to the ECU. There's an fault code in the BSI saying "No connection to the ECU".

I did some googling and found people having issuses with the fuel pump relay which could cause a unable-to-connect-to-ecu. I tried a new relay but no difference.

I intend to dig a bit deeper into the electronics but I thought I check here first if someone have had similair faults and have any ideas where to start?

And also, I've been googling for wiring diagrams but hasn't found anything of value yet. Anyone here who know where I can find such?

Best to you!
Thomas

Means nothing, also, BSI could be faulty the same

Would help to narrow down, establish what when it happened, that it doesn't start

x2 completely different things

I'd say do diagnostics or find someone with Alexia3 and DiagBox subscription

PSA ("Stelantis") hold it in their grip firmly, meaning, failing you find someone with appropriate diagnostic tool, that would read what are the actual errors are...
... got to be trip to StDealers... but don't hold your breath on it, as waiting time for diagnostics are 3 months  (at least where I live)

Thanks for your answers!

The car ran fine when I parked it in the evening. Next day it wouldn't start.

Got to be electrics then. Hard indeed to diagnose or to find a decent mechanic to diagnose, but all together simple physical check on ALL fuses(BSM, BPGA, BSI), then voltage/amperage measure up needed when starting.... if it does. Then an obvious culprit is wiring, connectors all in-between: Baterry> BPGA (batt fuse box), started solenoid signal>LIN connector to the alternator>BPGA-ECU wiring... ideally by a clued up mechanic, as DIY is often the case, you might look at something being wrong, but not see it   (happens a lot to me)
Good luck!

I think Alvy is right, could be so many things.  And tracing is not easy without the required knowledge or equipment.

Good manuals are hard to find but you might find something here:-

tee-cee posted this one a while back, I think it's still there:-

Re: Dispatch/Jumpy wont start (SOLVED)

Thanks for your answers. The wiring diagrams will be useful, need to fresh up my german first 

The car cranks but that's all. I hooked up my Lexia today but "nobody home", couldn't connect to any of the modules. Tried Autocom and managed to connect to the BSI but the same "Cannot connect to ECU" - fault code.

Feels like some kind of major electric thing. Have checked all fuses. So, time for the multimeter.

Turned out to be corrosion inside one of the ECU connectors.
Several wires inside the connector had no connection at all with the ECU. Among them one that went to the main relay which explains the "blackout".

Up 'n running again

Glad you got it sorted and pointed out a potential problem for the rest of us

Re: Dispatch/Jumpy wont start (SOLVED)

I've got the exact same problem at the moment. 2005 mk1 dispatch 2.0 HDI

Got to work fine

Finished work not fine 

Turns over fine, no communication via obd port and cannot hear the in tank pump priming

Changed the pump, changed the relay

Going to have a good investigation tomorrow evening but I don't do electrics

It's booked into a garage but I'll check over the fuses and connectors/clean where I can with electric cleaner and try a few other things members have suggested on my post

@northface well done for getting it sussed, hopefully it helps out Joshwaa too!
