connections

I bought this seadoo knowing it had starting issues. There are 1 and 2 connection points to the MPEM. I have noticed that when I lift up ever so slightly on #2 connection point going to the MPEM that the electrical connection is made, seadoo gives a few beeps, starts up and basically seems good...

have a quick question. i took my uncles ski to fix for him after a mechanic screwed him by not installing a new motor correctly. the mechanic removed the oil injection system and i am putting it back in. after looking through the service manual it shows 2 larger oil lines running to both sides...
