Love the paint! At the same time, it may be hindering a good ground connection somewhere. The alternator mounting points need to be bare metal, the starter mounting all metal, obviously any ground cables or wires, and sensors like temperature or other one-wire sensors that use the engine for ground.

I'm with Atoman in thinking it is security-related. You can try disconnecting the battery for a while to reset the system. That was probably why you were able to crank it to get oil pressure, and that used up your "free tries". The red security dot should not be on. Were any wires/connections in the steering column or down by the brake pedal/body control module disturbed?

Is that the same engine from the van originally? I see early valve covers that would be plastic on later models (2003? or 2004 -up). I remember talking about swapping valve covers with someone in another thread. If this is an early engine in a later model, there will be problems...
