I screwed up! Fuel System Wiring
Hi all, newbie here.
I've been searching for days and finally decided to make a post. Feel free to roast me because I KNOW I'm missing something obvious.
The story is I blew the head gasket driving my 85 4Runner with the automatic transmission in low, REVVING it out before shifting to 2nd, revving it out AGAIN, before shifting to drive. Like a hotdogging dummy. Next mistake was pulling the whole engine out because a friend had offered a recently rebuilt 22re with lots of work done on it. Deal fell through and I went on to reinstall my original engine.
In the process I decided to replace the fuel injectors and fuel injector plugs because the plastic was coming apart. I REPLACED THE WRONG PLUG! I have the right plugs on all the injectors but now I have one plug leftover and the truck will not run. Starts and dies immediately. Seems like its starting on the cold start injector and then not getting more fuel?
So heres where I need help. Please help me identify plug:
White with black stripe and blue wires.
It comes out of the harness into the engine bay along with the injector plugs and everything else.
The wiring diagram I'm looking at says its for the fuel pump and should being going circuit opening relay but i can't figure out where it should connect.
Jumping the check connector hasn't helped.
Maybe the issue doesnt have to do with this wire at all maybe its something else i havent learned about yet.
THANKS IN ADVANCE!

You are looking at the schematic for a 85 4Runner??
You did get the correct injectors for your year engine ?? I think they changed in 88 but not enough Coffee yet
Jumping the fuel pump connector bypasses all the fuel pump switches and relays and should turn the pump on.
If the noise level is low enough you should hear the fuel moving through the lines.
Maybe you have some corroded connections not allowing the injectors to open .
Disconnect the Cold start injector harness see if it still starts
If the engine was out and you have fuel to the cold start injector it seems the pump is not the problem
