Just got the new rebuilt engine back in my 07' 335i. I'm trying to fire it up, and it just cranks and cranks. I have LPFP pressure (82psi), Rail pressure (2200psi), all the ground are hooked up, I've checked every fuse I can find, no codes when I scan it....but for some reason, I have no spark from the plugs when I crank the engine over.

I've checked continuity from the frame, to the block, to the injectors, to the coils....everything is grounded properly.

Any ideas? I'm stumped?? Any help would be great!!!!

Strange.
WE are ok that you check that sparks works by puting one sparks electrode on ground surface then crank ?

To me injectors and sparks are drive by the dme so question IS why DME doesnt allow sparks supply.

Its like antitheft or something like that.

Well, I figured it out.......but it was mostly just luck. After checking grounds, wires, connections...everything I could think of, I had just about given up. Then I figured what the hell, might as well try to reflash the tune. Well...that did it. As soon as the tune got flashed again, I hit the start button...and the engine fired up and came to life!


Not sure what the deal was...maybe after sitting for almost a year with no power, something in the DME got corrupted? Glad it was something simple......

That's a good news
