What software are you using.. Tunerstudio I hope? I'd recommend buying the registered version and doing a crank position sensor log from the Diagnostics tab (composite log and tooth log). That will ensure you're seeing a stable and correct crank signal.

Then ensure you're seeing spark with the tried and true "pull the plug and look for spark" method.

Report back, good luck!!
Yeah I'm using Tunersturdio. I don't think you need the registered version to use the composite log and tooth log. I have the free one and have access to the diagnostics tab. I even data logged a composite log while I was cranking and saved it to a file. I need to pull it off the laptop I was using though. Do I view it with megalogviewer?
