zc injector swap issue

so ive got the zc swapped into my crx. started up and everything.

the only problem is that its running only on 2 cylinders.
A7 and A3 are the main injector and auxiliary injector on the DPFI side

for the MPFI transfer A7 and A3 become injector 2 and 4

for some reason only injectors1 and 3 and running. ALL of the spark plugs are getting spark though.

the wiring has been checked twice over and everything is good from the resistor box all the way to the ecu.

anyone know what possibly could be causing injector 2 and 4 not to be firing?

Re: zc injector swap issue

You are running a mpfi ecu right?

Re: zc injector swap issue

You have a wire on the wrong pinout, most likely... I know you say everything is good, but if you're running an MPFI ECU, etc... then that's almost definitely what it is.

Re: zc injector swap issue

either that, or you have a bad connection somewhere.. make sure nothing is taped up, and solder all your connections... if you don't, eventually, you may regret it..

Re: zc injector swap issue

You're supposed to change a couple pinouts when you do the wiring from DX to ZC.. a pinout == an area where a pin is attached to the wiring connector that plugs into the thingy, and allows the wire to make contact with another circuit.

Hes saying you may have some pins in the wrong holes on the ecu connector.
