Sprinter 310 D startet nicht mehr - Vorheizanzeige schaltet sich nicht aus

Hello,

Yes , transponder coil at ignition lock is the piece in circle around the ignition from where the small black wire is going to the TEMIC .

Sent you an email .

ok understood , i saw it is easy to dismantle.. As i have ordered a new diagnosis box at Eurocartool and i built a complete dedicated Laptop environment with a VM emulating old Windows XP , to run HHTWINS software (that i understand being one of the very few remaining tools able to diagnose a T1N) , I propose to wait to receive that box , make a diag, and then send you the TEMIC , transponder coil , ignition key AND the ECU.. And cross my fingers that it can be fixed ..

Just for fun , in case you reprog my ECU, do you think it is possible to emulate the code of a 312D instead of 310D, just to see if i can win 20 hp ? or are there other components to change like injectors , turbo etc .. to make this upgrade ?

And last question please , where should i send you such components ? what address please, let me know ? Of course i will pay you at least for the shipping !
Thank you again. Sincerely yours
Olivier BONNET

Hi guys , A quick update here as the Sprinter finally restarted this WE ! Thank you so much to you Sprinter75 for your precious help ! So i understand that the TEMIC anti start system was in defect and ECU software needed to be reloaded.. I would not have any chance to fix it without your help because Mercedes did not what to diagnose it nor sell any TEMIC box .Thank you very much for your kindness and your precious help, without which my Sprinter would have gone to the scrap heap. I must also recognize that Vanagaudi was right because there is a second problem related to a false contact at the support plate of the relay under the driver seat.. All the more vicious because we see no corrosion. This forum provides definitely the best support on earth to solve Sprinter issues !

To summarize the full story :
1) i had engine cut while driving , and it comes from diesel pump relay below driver seat (Instable wiring connection)
2) while attempting to fix it i missed to disconnect the battery and probably created a short circuit or malfunction that burnt the TEMIC antistart system and created issue in the ECU as well
3) I bought a diag device to Eurocartool.com, vietnanmese company that provides very useful support via WhatsApp and Teamviewer to make the installation and setup my laptop (Very complex in my case because the only software that provides diag for old Sprinter of 2000 is HHTWIN that needs to run on old MS Windows XP ! So they installed a VM on my laptop to emulate this old version of Windows) . then i got the diag of HHTWIN that concluded to the issue with antistart .
4) Then i sent the ECU and TEMIC to Sprinter75 that removed the antistart , changed a chip and reloaded the ECU and .. It works !
5) you can also take a look at the very useful support given on Youtube by Florida Van Man (https://www.youtube.com/@FloridaVanMan)
6) By security i changed the Crank position sensor+ pre heater tempo + Diesel pump Solenoide, i have also bought the camshaft sensor but i did not find it so far

Again great thanks to this forum and Sprinter75 that help me a lot . . Thanks also to Vanagudi that diagnosed the 2 issues !

Normelerweise versuche Ich auf Deutsch zu schreiben in diesen Forum, aber weil diese Thema auf English ist...

Thank you @BONNET for reporting the problem solving steps!

Is there a way to bypass the anti-start by hardwiring the fuel cutoff solenoid from ignition lock KL15, as some posts suggest? If that is possible, is there a way to prevent warning lights to appear?

[BONNET]

In fact when i was trying to find the issue , i attempted to put a wire directly from battery + to the Pump solenoid and i saw it was opening the solenoid because i felt and heard the clic.. BUT it never started.. I tried to force the start with some break cleaner in the intake manifold (Which i definitely do NOT recommend) but even with that , the engine talked 1 or 2 seconds and stopped again.. MAybe you can ask this question to SPrinter75 that is highly expert in this domain !
