van was running rough so I changed the spark plugs and wires, starting running worse and code P 0206 and P0206 and P0355, P 0356, replaced ignition coil and still had codes P0206 and P0205, replaced both 5 and 6 injections and still have the code and now white raw fuel smelling smoke and vehicle chugs and sounds like it wants to back fire and stall. The smoke is really heavy when first started. The injectors voltage for 5 and 6 are fine, they are getting spark. Prior to this happening I was getting a small leak and large leak code but I have since replaced a few lines and am no longer getting those codes.

You're having a problem with the control circuits for both the injectors and the coils so I would look into that deeper. Verify the integrity of the wiring, look for rodent damages to the harness. You can use a noid light to test the signals to both of those components. You can do an injector leakdown test to determine if anything is going on there.

I have examined the wires and there is no visible damage, could it be a sensor? I turned the car on today and also received the normal P0206 and P0205 code as well as new codes P 1193 and P0508

Are you sure the plug wires were replaced in the correct order? Were the new plugs properly gapped? Also, have you noticed that the coolant level is getting low?
