have had a hard start when facing up hill all the fuel return seals replaced. Now if its pointed up hill and plugged in at night it fires right up, and i have a p122 code,the hard start started when the weather started getting cold could use some input diagnosis on this. thanks

the uphill hard start was a fuel return line leak on the back of the head and the fuel pressure guage line was letting air in,the 122 code i think was low batteries or a ground,erased code hasn't come back.
