I have fuel pumping but not getting to the rail on the drivers side. And looking at the hose coming from the passenger battery area side I see there is a connection junction half way point over to the drivers side rail. Is this the cold start valve? Because I have this white wire not connected and another plug with a boot on it not plugged in also. Any idea where the white wire connects to?
And the other question is. ...... if those 2 things are not connected. Would that prevent fuel from moving to the drivers side rail. And the injectors not firing? And if there is fuel on the passenger side rail and not the drivers side rail, would that all prevent ALL injectors not to fire? Very much a novice here..... and thanks in advance for any info or a diagram of where that white wire plugs in to. Right now I have it cranking, fuel pump pumping.... but not firing up. I have checked for spark at the plugs and have that. Attached image(s)
