    Will Not Fire

    After pulling my injectors and rebuilding, they car is turning over, but not firing. I have checked all hoses and connections, but all things are in their place. Any ideas on what it could be? 1989 325i m20b27, stock injectors.

    Checked your fuel pump? Are you getting spark?

      It worked fine before hand, if it were the fuel pump, how could I tell?

        Might you have gotten the fuel supply and return lines swapped?
        The car makes it possible, but the driver makes it happen.

                Nothing of the sort was tampered with, it's all where it was before.

                  I checked the fuel pump relay and main relay, both click once when the ignition is turned on.

                      Jump fuel pump relay number 87-30 and see if it comes on, you can disconnect fuel feed line and see if fuel comes out also.

                        Found out, no Injector pulse. Checked the connectors and everything is in place. What could be causing the issue?

                          no crank signal = no injector pulse

                              doesn't mean the signal is getting to the DME.

                              are you sure the CPS and CID weren't switched around?

                              does the DME for 100% sure have power?
