After I started the car I noticed fuel leaking from ethier a possible busted fuel rail or did I miss something on the fuel injectors wiring. I am going full obd1 that is the injectors, dizzy and ecu p28. From what Blownhatch told me is that I dont need a resistor box for these injectors so what I did is connect the the 2 yellow/black wires from the dpfi to the 8 yellow/black wires (junction c128) connection I cut off the obd1 harness to extend other 4 yellow/black wires on to the injectors. So what I want to know is if this wiring correct? or did I screw up or do I need to ground a yellow/black wire from the junction 128 connector? Or maybe I need a new fuel rail. Any help is great.

 

check the injector seals first, i dont see why you would be leaking fuel through wiring.

 

Thanks Ill check my injector seals.
Does anyone else have anymore sugestions?

 

make sure all of your fuel lines are on tight. I didnt tighten the FPR line and it leaked all over the place. Fuel rails don't usually break. Most likely its the seals.

 

make sure you have all the washers that go around the fuel lines. where is leaking from eaxtly ? from the injector or from the line ? or like where the injector meets rail or where the injector meets the head or where the fuel line meets the rail.

 

Its leaking from the injectors Ill check the seals today.


Thanks guys
How about my mpfi wiring I know the (red, brown, lt blue,yellow wires) on the injectors are ok. But how about the 4 yellow/black wires. I basically have them wired all together with the other 2 existing yellow/black wires that came from the dpfi red, yellow injectors. Is this cool or is it wrong?
Since they are d16z6 injectors and they dont need a resistor box I really dont know how to wire the yellow/black wires I am guessing my wiring is correct unless someone else proves me wrong.

 

yea, check the o-rings around the injectors. a chewed up / bad o-ring will cause a lot of leakage...

 

It is the O ring. That is exactly were it is leaking from.
Thanx

a lot cheaper than buying injectors or a rail...
...like some of us idiots do.

 

Cool thanx.
How about my mpfi wiring, I am still questioning it I did this since someone was aking about this on another thread when I did a search but there was really no final answear.
