I have a 93 BMW 325is with a no start issue. It cranks but will not start. It has no fuel and no spark. I also have no power to the fuse 18.
In following the above thread, I jumped the Fuel pump relay pins 30 to 87 and got power to the fuse, and at the pump under the rear seat and subsequently fuel to the fuel rail.
Steps I've taken:
1.Tested Crankshaft position sensor =520 ohms
2.Next went to DME;
DME relay results:
Pin 85 Pin 86 Volts with ignition on 0V 12V Volts when cranking -0.08V 11.27V
3.I also checked the Fuseable link in the trunk, it looked fine. (The outside insulation was perfect)
I think my issue is DME related but need ideas to solve it! Thanks.
Yeah you have a '93 so there's a good chance your DME has corrosion. You can try cleaning it, open up both sides, get a can of Deoxit 5%, spray it down liberally, scrub everything with an old toothbrush, repeat 3x. Let it 1000% dry out.
When things work properly the DME only energizes the fuel pump for 2 seconds.
Post pics of your DME before and after cleaning. Buy the Deoxit its far better than regular contact cleaner (Amazon, eBay, guitar store etc.)

IMG_0298.jpgIMG_0299.jpgIMG_0297.jpgThe one side I inspected showed no signs of water damage/ entry. The other side would require drilling out that white plastic 'insert' which I don't think I should do just yet incase I damage the dme board. However, I can revisit this step after further verifiable testing steps are carried out.
Unfortunately your pic doesn't have the focus or resolution to see if there is an issue.

DME looks good, you should be able to squeeze and push the plastic plug out from that side. The board looks like its been coated by someone.
