So everything is wired up and she cranks over and whatnot, butt I have no spark. I'm pretty sure everything with the EWS is wired properly, but maybe not? I have power and ground at my coils, but I don't think the DME is switching them on and off. The unloaded relay from the original harness has been wired up but still no switching. Any ideas where to look?

I'm having this problem on my 540i now. Some say the crank sensor do a ohm test on it. then a stomp test. Check all the dme, fuel pump, injector, fuses -
Would the fuel pump not being connected cause a no spark issue? I haven't wired in the new relay they and I toyed with that idea, but I didn't know why that would mess with my spark.Comment
