Hello. My name is ***** ***** shift switch does the spark return? This switch is down on the shift linkage. Just unplug the switch. Do you have spark now?

Won't fire at all now
Expert:  Tan replied 1 year ago.
That switch will not kill all the spark. It only affects 3 cylinders. If you have no spark at all then you have another issue.How are you checking for spark?
Customer: replied 1 year ago.
Now it won't start. When it was running before I pulled that switch I disconnected a spark plug at a time and it had no affect

Can you give me suggestions to why the left 6 cylinders wouldn't you be firing please
Expert:  Tan replied 1 year ago.
Ok we need to disconnect the black/yellow wire at the power pack # ***** You will need to pull the cover # ***** of the power pack and disconnect the top plug on the port side of the power pack. There is only 3 cylinders on the left side. But no spark on all cylinders can be many different things. Any one of these components can be bad, Power pack, stator, optical sensor or rectifier/regulator. This is going to take some time to figure out the problem. The disconnecting of the black/yellow is the first step.

why did i disconnect that switch I ended up breaking it , ur wasting my time man this whole things a f**king joke
Expert:  Tan replied 1 year ago.
I didn't tell you to force anything .I said unplg that switch. This is the shift interupt switch if it shorts out it kills spark to 3 cylinders. What you did din't cause the loss of spark to all cylinders. I can fix this motor if you want to but if you think this is a waste of time. Ypou can take it to a dealer and they will charge you 100 dollars and hour even if they don't fix it. Good luck I guess you don't want my help.By
