View Full Version : "start error" and fuse block

09-04-2013, 07:00 PM
My 2005 sprinter developed the "start error" problem a few weeks ago. The WSP and ECM were both getting power and I ended up sending the WSP, ECM and keys off to SOS diagnostics. They restored software without replacing any hardware and all was good for a while.

The problem has now recurred. I suspect the fuse block under the steering wheel may have something to do with it. The turn signals occasionally stop working, which I can fix while driving by whacking the panel cover with my hand. Could it be that by doing this I am jiggling a bad connection and interrupting power to the ECM or WSP while the van is running and corrupting software?

Any thoughts?

The starter battery may be too low on volts and amps to start giving the start error, the battery may be on its way out.
Or the skreem connection may be imperfect. Try lifting up on the fuse panel while pushing down on the flasher and multifunction switch to get a closer connection. Or replace the column fuse panel

Im having kinda the same issue. Does your aux fan run in front when it wont start and does the glow plug light stay on? I usually tap the ecm relay under the steering wheel and it shuts the fan off and starts. I replaced fuse block 1 and still cant find the problem.

Good information.

I especially like the cable tie solution for the broken holding fastener assembly. Simple and effective. :thumbup:

One recommendation that I would add is to always use a black cable tie for similar repairs. White nylon cable ties have a tendency to get brittle and weaken over time, especially if the cable tie is subjected to sunlight. Black cable ties are generally not nylon and suffer less from that problem.

Cable ties also work well to hold the grill in place after those lower fasteners have failed. Mean in Green used ties to repair his failed heating system control cable mounts also. Gotta love cable ties.
