You mean on your B230F engine right? That is simple enough, pull the two 10mm screws out of the intake manifold that mount the fuel rail, pull the rail complete with injectors and supply/return lines connected. Pull the negative wire off of the primary side of the coil and crank it over via the remote starter connection by the left front fender. I doubt that this will help you figure your problem out though and honestly if you cannot figure out how to check the spray pattern then you probably do not have enough experience to know what a good one looks like from a bad one. I have never had an LH injected car that ran rich because of a funky injector spray pattern. We used to have problems with this in the old CI beasties but the electronic stuff is much better in this regard.

Good luck,
Mark
