Capt Greason,
I would suggest that the fuel system has previously been inhibited with something like Aeroshell 1. We used to use this in the test-cells, to preserve the delicate fuel components from corrosion, before engines went back to the customer for storage.
When you try to relight an engine for the 1st time that's been inhibited, the Aeroshell 1, which is actually a very thin 'oil', burns like they are announcing the new pope at the vatican. Until it clears from the fuel system you will get smoke like this and the engine will not fully 'fire-up', because the mixture is about 50:50 of oil to kerosene.
Hope this answers.
Best Regards,
