79 450 SL cranks but won't start (of course)

I am looking for a little guidance on where to go next and hope someone on the forum could provide it. My 450 SL has sit for a couple years with very little operation. Now it cranks, but won't fire. To date, I have completely re-worked the fuel system (tank cleaning, new strainer, fuel pump, filter and accumulator) and now get a great fuel aerosol spray from new injectors. I replaced the spark plugs and verified that I am getting a spark. The cold start valve was replaced a few years... 79 450 SL cranks but won't start (of course)
