It sounds like the Injection Pressure Regulator went bad, but can I ask if you have run the codes? This guide can help, also how did you come to find this problem of grounding the wire to make it start?

If no codes are present here is how to change the valve out for a new one in the images below. You can find a new unit on Amazon for $49.00.

Please let me know how it goes.
