ls in ef issue

[Patm91]

solved.bad coil. thanks everyone!

[ct tibby]

the resistor box must not be wired right

[Patm91]

i connected all the wires going to the resister box cuz obd1 injectors run 12v right? so the resister box becomes eliminated

[CTgoldhatch]

if you have obd1 injectors you dont need a resistor box and it soulds like you have the mpfi conversion wrong

[Maximumautollc]

some odb1 injectors need a resistor box, depends on the year

[Patm91]

b18a1 supposedly out of 93 integra

[CTgoldhatch]

obd1 injectors dont need resistors if you want to keep the resistor box run obd0 injectors if you want to get rid of the resister box run obd1 injectors

x2^^

[Patm91]

thats what i did im running obd1 injecters with no resister box.

[Patm91]

i did this:

Optional Injector Wiring:
This is if you decide to run obd1 injectors opposed to obd0 injectors. -cut the obd0 injector clips off of your obd0 engine harness
-solder obd1 injector clips in place of the obd0 clips
-unplug the injector resistor box
-cut the wires leading to this box
-connect all of these wires to eachother. If possible use the gray plug off of an obd1 engine harness which on obd1 setups does this very thing. If you do not have this plug, then just solder the wires together and heat shrink or tape up the exposted wires.
Note: You do not HAVE to convert to the different injectors. Both work equally well. Whether you want to swap is based on personal preference, your specific needs, and what parts you have on hand.

[CTgoldhatch]

then your injectors should be good now you just have to make sure you have the rest of the mpfi swap wired right

[Patm91]

yup they are thanks! but i have no spark now...

[Patm91]

anyone got a running ls i could test my dizzy on?

[Maximumautollc]

93 integra is odb1 but uses low impedence injectors. You need a resistor box. It's possible ur ecu failed because of this

[lowcruzinteg4]

or theres usually 2 white wires on the dizzy u try switching them i ve ran into that before
