MPFI Fuel Injector Order On Manifold?
Hi,
I just wired the injectors to the ECU and I wanna make sure I did this right. The fuel injector order goes 1, 2, 3, 4 from left to right on the fuel rail right? DX injectors go to 1 and 3 and ECU injectos go to 2 and 4 correct? Also, how do I test my injector resistor box to find out if its good? Thanks

no man, injector 1 is by the crank pulley side of the engine, and 4 is by the transmission side of the engine.

Alright I am soo confused.
on this pic http://files.automotiveforums.com/up...87289dpfi2.jpg it says the injector order is 3,1,2,4 from left to right on this one http://www.angelfire.com/d20/hcivic8...i_diagram1.jpg It is 3,1,4,2 from left to right which one is correct or will they both work? So I take the yellow DX wire and connect it to the #1 injector Red DX wire to #3 injector A7 ECU wire to #4 injector and A3 ECU wire to #2 injector

Re: MPFI Fuel Injector Order On Manifold?
This is how stock mpfi cars are setup such as the 88-91 crx/civic si:
looking into the engine bay on the intake manifold from left to right: yellow, blue, red, brown, 4 3 2 1 at the ecu: a1: brown: injector #4 a3: red: injector #3 a5: blue: injector #2 a7: yellow: injector #1 hope this can help. also, when I did my mpfi swap, I ran the same color wire directly from the ecu to the injectors. I didn't do any cutting or splicing. I just deppined the yellow and red injector wires at the ecu and repinned the them in their correct locations. I suggest this so that there isn't any breaks in the injector wires.
