Crank no start with M54 swap

[clarinetnerd]

Like the title says. M54b30 from an automatic e39. Chassis is '91 325i. DME is MS43.

• Turning the key to on gets the fuel pump going, I can hear that clear enough.
• Spraying brake clean (the flammable kind) down the intake doesn't help, so it isn't getting spark.
• After cranking for a while (probably 10+ seconds) I can't smell any fuel, so I don't think the injectors are running either.
• No fuel and no spark tells me it's probably EWS.
• Using MS4x Flasher, I wrote MS430069 (with MS4x wiki's immobilizer bypass patch) onto the DME. Crank, no start. Tried it with an unaltered version of the wiki's MS43x custom firmware, which has the immobilizer bypass patch included. Same result.
• MS4x Flasher shows me a half-dozen diagnostic codes:

A little poking around online gave me definitions for most of these:

• DTC 113 is motor throttle valve potentiometer. That makes sense. I swapped the throttle body for an M52 cable throttle. I realize this might also be causing problems.
• DTC 11 is coolant temp sensor at the outlet. Makes sense; that sensor isn't plugged in any more.
• DTC 35 is the secondary air pump. Makes sense, that got deleted.
• DTC 140 and 126 are evap related.
• 125 is for the cooling fan.
• 115 is "range check for throttle position adaptation". Read above (at 113) for the throttle situation.
• And DTC 69 is for the fuel pump relay, which makes little-to-no sense.

Other than the throttle situation, this is a fairly basic swap, following the guide posted on this forum. I did rebuild the VANOS while I was doing everything, but I can't imagine that would have any impact.


Let me know if you need any more information.

I'm really out of ideas and I don't know where to go from here.
