    I went to my moms and took a nap (she lives 1/4 mile away) my buddy eventually called, he was working on his house. We got it pushed in finally but unfortunately didn't make much progress. I'm new to electrical issues and diagnosing so while I've been learning on this whole swap, this is what I was dreading the most.

    So after switching fuel lines and double checking the Crank and cam sensors were correctly hooked up, I put the booster pack on the battery and tried cranking again...still nothing. So I'm at a bit of a wall, I can confirm the following..
    -fuel pressure seems strong still
    -CPS tested at 505ohm which is in spec (it is the one that came on the motor, should replace anyways?)
    -ICV is humming with key to 'ON'
    -fuel pump isn't priming but runs with the relay jumped
    -will fire if carb cleaner sprayed into intake so seems to be getting spark

    All of this leads to me think the injectors aren't firing. Now the cause of this I'm not sure of obviously. The DME was supposed to be good but I can't verify. We tested the main relay last time and it checked out. I switched the other relays around for other ones with no different results. While cranking it will occasionally sputter like one cylinder tried to fire and have a faint smell of burnt fuel (open headers still). We checked all the important grounds last time and they were good. Hooked up to the booster pack so it's a strong 12v constant power. So with my limited but learning knowledge I'm lead to believe that I either need a cam sensor or I have a fried DME.

    This was the car before we got it pushed out, it had sunk nearly to the depth of the tires.


    This is my distribution block. I check all wires the running to the battery lead are indeed red and the grounded wire is brown, also have the passenger side ground strap from the chassis to the engine mount and injector harness grounded at the engine lift hook.


    I pulled my plugs and they looked dry which I would suspect is from the injectors not firing.


    And lastly I decided I would atleast wrap up the mechanical side of the swap and install my driveshaft...till my E30 CSB imploded when I pulled it off the DS. It's bent because I unleashed a large amount of violence on it once it tore, was a stressful day.


    Any advice or tips on the no start issue are HUGELY appreciated. Been searching around but the amount of different threads on this is subject is a bit overwhelming.

      Hey good luck with this don't get discouraged you're almost there. There is a test for the injectors you will need to confirm if they are firing (have power) or not. If not could be a ground or a bad DME... anyone to borrow a known good DME from? If you have electric pulse to the injectors your dealing with fuel delivery.

        Thanks, it's only discouraging because I can't pop out my back door and work on it. I usually only get about 5-6 hours a week. I've got a new DME on the way and I found another good tested (540ohm) crank position sensors amidst my pile of parts that I'm going to try. Hoping I can atleast get it to run, then sort out the other issues.

        Also, I've noticed I apparently don't even have a CEL bulb in my cluster. For some reason it never occurred to me that it was missing. Could this be a problem? I'm going to replace it regardless.

        I've got a thread in the M/S50 swap forum for troubleshooting and someone mentioned the E36 harness requires the DME to be grounded...but I have extra ground wires to do. Can anyone confirm or elaborate this?

          Tried two other DME's and a different but still used crank sensor. Still no go. So, ordering a new CPS tomorrow and hoping it shows up mid week and I'll drive up and see if it fires.

          One thing I have learned from this swap, because the goal was budget minded I tried to cut some corners or re-use questionable parts. When I really should have bit the bullet, ordered everything I thought I would need and ended up buying anyways and doing it right the first time. Now dragging on four months later and about the most basic M50 swap still hasn't fired. I've learned a lot about the process and working on my car in general. I bet I could have done this work in a solid weekend if I went back and did it over. Oh well, I wouldn't be driving it right now anyways.

            thiis happened to my car after my swap and it ended up being the obc relay box. Had to bypass it, don't know if the obc is the same on your car though

              Don't beat yourself up too much! When I did my M30 swap, it dragged on for 6 weeks when it should have been done in a weekend as I had all the parts I needed before I started, and the engine & gearbox were in within a couple of hours of ripping the M20 out! From there it seemed that everything that could go wrong did, with some things (like swapping the gearbox in my driveway and replacing the starter being an absolute PITA!) but my Dad who's a mechanic pointed out that it's the swaps that give you the most trouble that end up being the best, most reliable ones because you end up spending the time to get everything exactly right and you go through everything.

              You're nearly there :up:

                Holy shit it runs!!!!

                Threw a new CPS in, sanded all my grounds and after a bit of cranking it fired to life!

                  Congrats dude! Must be a great feeling, i too got a bit depressed reading the early part of trouble shooting. I'm sure hearing it run is very rewarding.

                          It was a huge relief that's for sure. Been trying to start it for about 4 weeks.

                          Soon as I order a new CSB and get the driveshaft and bleed the clutch ill roast em!

                          Shit man I wish. Was stuck in Ohio in -4f weather.


                          Didn't think I was going to get to work on it. Snowed in pretty good.





                          So stoked it fired up today. I started out by putting the new Crank position sensor on.


                          Then I took all thr ground wires off, filed everything to nice fresh metal. Not sure if this really had an affect but can't hurt.


                          Then, well..it started. Sweeeeet. Video if you click the image.


                          Started cleaning up wiring and zip tied the harness up to the firewall. Need to figure how to get the relays to sit in their little holders. Ordering the m3 firewall cover for the passenger side.




                          Went to hook the exhaust up. Using obd1 manifolds from an e34. The y-pipe I had is from the e36 the motor came from. For some reason they don't line. I cut the y-pipe into individual pipes and the front header flange doesn't seem to line up at all. Is there a difference between e34 and e36 manifolds?






                          Hopefully next weekend, the car will move under its own power!

                            Just cross referenced part numbers for the OBD1 headers and I was correct. The front set of headers is a different part number between the E36 and E34's but the rears are the same. Oh well, picking up some OBD2 headers from NickL this week. Another one of those "should have done in the first place" things.

                              It moves on it's own again! You can see my surprised and relieved look when the clutch engaged perfectly and it moved first try. Had my brother stop by and help bleed the clutch, reinstalled the driveshaft and tightened up some odds and ends. Still has just headers on it but it runs and drives. Next up I'm trying to find a good condition OBD1 front manifold as I decided against using the OBD2 for the time being. Then it's off to the exhaust shop to get the y-pipe mated to my existing exhaust and it will be on the road! Oh and I need to check my thermostat housing as it doesn't seem to have fully sealed.

                                A bit noisy but damn was it nice to take thing down the road a bit. Exhaust to get finished up next weekend, then it's simply little details to sort.
