mehr4x4 Eric No Start Temporary Solution
Eric mehr4x4 has a rather ingenious jumper circuit which may help as a work around for no crank/no start.
I'll begin by posting some quotes from another thread.
It should be noted that Eric's jumper method does not provide the power off delay for orderly shutdown of the ECM which is normally accomplished via the Engine Relay (M) circuit and possibly (probably?) the Timer module in the FB #1.
If you have a no crank situation it is worthwhile to note which dash icons remain lit after the dash warning illumination check cycle. On older T1N models (NAS aka NAFTA 2001 - 2003 OM612 engine) the dash will look similar to above. On NAS aka NAFTA 2004 - 2006 OM647 engine models the only odd dash light remaining lit may be the oil can with drip. Installing the jumpers should help in that situation.

aaronschof, Sorry that I didn't get back to you earlier. Been quite busy. I'm actually on a computer instead of my phone so let me see if I can get this to work. There are several ways to confirm what is going on here. I'm not sure how much of this is exact for yours not being from the state's such as mine but I'll try to help.
When I have no power going to the engine ECU, or they call it the engine control module but we will call it the ECU for reference sake, the following will happen;
When I turn the key to the on position the engine electric cooling fan will come on, all the dash lights momentarily will come on but the "water in the fuel", "glow plugs", and "Oil" lights stay on and don't go out (Pic "No power"). Turning the key to the start position causes NOTHING to happen, no click, nothing.
I understand that your van may or may not have the same electronic engine cooling fan so i don't know if this applies but it is a symptom for mine.
When I have power and everything is working correctly the following happens;
When I turn the key to the on position the engine electronic cooling fan will not run, all the dash lights momentarily will come on and only the normal lights remain on such as the "battery", "ESP", and "Traction" lights (Pic "Power"). Ignore the check engine light, it's a glow plug module and unrelated to this problem. And when I try to start the engine it will click on the relays and start the engine.
If it were fuel pressure, or starter relays, or starter motors, or SKREEM problems you would have other symptoms. The first 3 listed above WILL give at least a click of some sort and the lights would be normal.
One "easy" way to confirm this is the problem is to remove the center relay (in Pic "Fuse Box1") and jump the two larger contacts with a made up wire. Use two "male" spade connectors (Pic "Connectors") with a wire and push them into the two larger slots (lower part of Pic "Drawing" ) This will energize the ECU and the van should start with the key. Shut the engine off. Don't leave the jumper in there as it will power the ECU all the time even with the key off. Just use this to confirm this is the problem.
If the above works then do the following until you and I can find a permanent solution;
I used a combination of male and female connectors to make jumper wires and fuse sockets to power up the 2 fuses for the ECU. I found some fancy combination male AND female crimp connector that had both spades on the same crimp. Sorry but I don't have a picture of that. You can just use a larger yellow spade connector and push 2 wires into the same connector, that will work to. (Pic "Connectors") I pulled fuse 6, 16,and 17 out. Make up 3 short wires, about 4" long with a Mc (male connector) and Fc (female connector). Then cut 3 more 4" long wires and crimp as shown in lower (Pic "Drawing") Push the Mc into the right side of fuse socket 6 and connect the first Fc to pulled fuse 6, then the next Fc to pulled fuse 16, then the last Fc to pulled fuse 17. Now take the first 3 made jumper wires and push the first Mc into the left side of fuse socket 6 and connect the Fc to the empty side of pulled fuse 6. Second jumper goes into the right side of socket 16 to pulled fuse 16 and then the last one goes into the right side of 17 to the pulled fuse of 17.
Now turn the key on and see if everything seems correct with dash lights and try to start it. I bet (virtual) money that it will start!
I hope this makes sense. If not please feel free to ask questions on what I did.
