I converted a m20 to m30 in my e34 i have igniton and fuel but my fuel injectors dont seem to be opening because it cranks over but wont run any answers to what the problem could be woud be much appreciated.

Are you sure its the injectors? There could be alot of other reasons why it doesnt run.

I'm pretty sure i mean the computer is fine it works in my 88 535 and ignition and fuel is there for sure but she wont run i dont know a friend told me it might be my flywheel because i tossed a m6 flywheel a e30 m3 transmisson with an m5 clutch in it so im kinda sceptical it also might have something to do with my alarm or a relay but i still cant seem to figure it out yet but thanks for any advice.

Its not going to be the flywheel. There are three ingredient to making the car fire. Air, Fuel, and Spark. Check the fuel pump and see if you are getting fuel pressure. You can check your spark and see that its firing but if its firing at the wrong time. I had this problem once, the harmonic balancer was mis aligned becuase the key that held it in place sheared. Are you putting a M30b35 in your E34 or a M30b34? Did you swap the entire engine harness? Have you checked your grounds (the injectors work as a switched ground) THey're also batch fire, meaning 3 injectors fire at once. The spark plugs can also foul very quickly. That was a problem I had when I started my car on a stand-alone system. Take them out and clean them.
