- 312 sprinter camper om602 tdi 1996
Hi to all.
Bit new to this but no stranger to the ongoing issue with my sprinter 312 2.9 1996 w903 campervan. I sincerely hope I can move closer to rectifying the problems with all your help..SOS
Bought this van with 110k on the clock , engine running well plenty of power in 2017. I had been looking for this engine in camper form for a while... 1.5k miles later I was home and quite impressed with the power for passing lorries etc. The next day The engine shuts down while driving . has been an ongoing problem with this van before me, the previous owner just forgot to mention and by pure luck ive managed to get it back to base but from then on the symptom have been getting increasingly more frequent A real pain!!
The engine shuts down while driving . There are no warning lights on in dash. Engine running perfect, shuts down ,turn ignition key to off and back on would fire up whist on the move. Failing that, turn off at key disconnect ECU plug, reconnect, turn ignition on and fire up ,running perfect. , disconnect the battery reconnect, turn the key fire up and run well.
This is as much as I can tell.. When engine shuts down there is no power to the blue/black wire going to the fuel shut off at the pump.If I disconnect the battery and reconnect there is
power back to blue/black feed wire to the fuel shut off. engine fires and runs well but stops.
So I found the same blue/black wire in the rectangle plug located in an upside down bag behind passenger headlight. spliced into that wire before the plug and ran it direct to the fuel shut off thinking I was onto something. Van fires up runs well but stops 5miles e.g Left it for a while eventually fired up and drove home. Disconnected the battery and left it for a couple days. reconnected ,turned the key fired up sounding crisp. Didnt drive it.
PLEASE READ ON..
Booked van in on tuesday 8.30 Local Auto/diagnostics garage. Van drove 25miles never missed a beat. Left it with the guy, got a call back van running well wasnt able to read the ecu. Never Bothered.... Anyways collected and returned 25 miles running well. Took it to another garage today, never missed a beat plugged it in and communicated to it alright. Showed 8 issues, expected that from the messing around Id been doing. Removed all codes and also disconnected the direct wire I had spliced in to the fuel shut off. so ECU codes removed and back to original blue/black feed to shut off. Van running well 20miles in engine stops,wouldnt start by turning off /on while moving, stopped turned off/on and van starts,drives well 20miles back. Plug van in again and the same 8 issues are listed again??? All codes removed again
The van runs perfect engine stops 23 miles in. Wouldnt start off the key, give the glow plug relay a tap ,checked main fuse ok,turned the key and drove another 3miles to the house. itermittent power failure to the pump
I removed the relay, cleaned posts,checked connectors. cleaned contacts on copper switch inside relay box. inspected and dressed as much of the loom as I could get my hands to, looks better, installed glow plug relay, connected the battery, turned the key, fired up straight away sounding crisp but havent drove it anywhere.
The van will start run well for 5miles 80miles but will stop again. Thats as far as Ive got ....
Apologies in advance for the rant, I hope this makes some sense, and appreciate any help.
This van has the distributor pump,, electrical with the throttle body mounted on the bulk head.
