Thank you Jim, just to clarify (as I fear that any mistep here has a chance to ruin my engine in some horrible way) do you mean to pump the primer pump while cranking at the same time, or pump for a while, then go to the driver's seat and crank for a while, and then do it again? Also, I will try to use other resources to find out how to loosen injector lines, as well as where exactly those are, but any pictures or guides anyone could provide would make me massively more confident in what I'm doing. Thank you again for your help.
