    Does anyone have the procedure for testing this? I can't find my Bentley.

        I don't see how push starting it would make any difference...

              First post states fuel and spark present.

                    We pulled a new huge one out of my friends e34. Definitely have sufficient voltage.

                        Assumed so but was worth asking. Too much fuel as well? Maybe cold start valve acting up.

                          We pulled the plugs and let the fuel evaporate after the first start attempt. The fuel pressure regulator is also brand new.

                          There is definitely a fuel smell after attempting to start it, so it's getting fuel to the cylinders.

                          It almost sounds like, at least to me, like the cylinders are firing out of order. On the first attempt, there was some minor "back fires" or incomplete combustion episodes.

                            You're saying the cold start valve may be stuck open? It should still start if we pull the power the CSV right?

                              What does the flywheel position sensor control? Spark timing? Or just spark in general? (We've confirmed presence of spark on each plug.)

                                Spark timing is controlled by the cap/rotor and is non-adjustable. The flywheel sensor only controls fuel injector timing IIRC

                                It may or may not start with the CSV disconnected, depends on the ambient temp.
