2004 E53 4.4i Crankshaft Position Sensor Voltage? Crank No Start

[SCAP]

EDIT: FIXED.

Hello,

I bought a non running 2004 X5 with the 4.4 engine from a guy who works at a used car dealer. He seems to know his way around and just wanted this car out of his garage as he didn't want to deal with it. It was towed to my house.

He said he was washing the engine bay and was going to fix a power steering leak to get it ready to sell. Said it drove beautiful. But after washing the engine, there's a crank no start. He said there's no spark. I haven't checked it yet as I don't have someone to crank it for me but that will be confirmed hopefully in the next day or 2. I do have fuel pressure at the rail.

I am borrowing an Autel Maxisys and am analyzing data. EWS checks out and I don't think that's the issue (although the key is kinda wonky, the shell is taped together). When I crank it, RPM reads 0 during the crank. I picked up an extra crank sensor from the junkyard just to try it. Same thing. So I put my DVOM on the Crank sensor connector, the middle is ground and one I think is supposed to be 5v reference and the other is 12v. However one reads -9v and the other reads -11v!!! I looked at the connector and I think it goes right to the DME.

Some note to add, this car sat in my driveway without a battery for about a month or so. It has a new (remanned) battery and it's strong at 12.4v.

Any ideas? I bought the mitchell online repair manual but info seems to be lacking. I thought there might have been a troubleshooting flow chart, but I guess not. Might spring for the Bentley hard cover manual but I want to get this started.

Thanks

EDIT: The IVM (intergrated power module) was bad. It sits in a black box in the same compartment under the cowl as the DME. I pulled the connectors off and it has some fuses on it. One fuse was blown. The connector pins had green crusties on it. I swapped it out with a junkyard one. Fired right up. Had "Engine Program Fail Safe" (limp mode). The module next to it is the VVT VDO module. I pulled that and same thing, green crusties on the pins. Replaced that with a junkyard one and the engine failsafe was gone. Basically inspecting DME, VVT, and the IVM is a great starting point.
