Hi everyone !!
after having an head gasket on my OG D16Z2 engine i decided to swap by D16A9 engine ,
I kept the EE4 4WD speed, the motor wiring from Z2 on A9 (i ll explain the wiring plug changes next)
I ve used the butterfly fom Z2 to A9' PGMFI coz of inexisant tube on A9'butterfly


then i follow that thread from here

Re: Help needed! Swapping a D16a9 into a 1.6 16v Civic 4th gen. (puk)the D16A9 is the same engine as the JDM DOHC ZC and installing it in your Civic should be the same as installing the DOHC ZC into a USDM 4th gen Civic - you need to swap the entire engine wiring harness from the 1.6 engine that was in your car onto the D16A9 - all of the connections for the sensors, etc. will plug right in, with one exception which is the distributor connector - the ignition distributor on your original engine has 2 connectors, one round 2-wire connector and one round 7-wire connector - the distributor on the D16A9 has one round 2-wire connector and one square 5-wire connector - you need to take the square 5-wire connector from your A9 engine wiring harness and swap it onto the other harness, which you will be using, to replace the round 7-wire connector - when swapping it , you just match the wire colors in the connector for the engine harness with the wire colors in the connector on the distributor - you will have 2 wires left over when you swap connectors, one blue with yellow stripe and one blue with green stripe - you need to add a short length of wire to these 2 wires so that they will reach the Cylinder Position Sensor which is on the end of the exhaust camshaft - the silver thing just in front of the distributor in your first picture, with the green connector - cut the green 2-wire connector off the A9 engine harness and connect the 2 wires to it, again matching the wire colors






actually after reading that post i ve discovered you could buy the inter plug straight from web so i help myself also from the picture ....
Rywire : OBD0 MPFI to DOHC ZC Distributor Adpater

from this i ve done that







Then i ve used my Z2 collector coz the lambda sensor got 1 wire as my hardness wiring
Pluged my A9 ecu with is resistor box .
battery
turn the key ,
the ECU make his blink , can hear the fuel pomp
starter works but no spark !!!
I ve tried it all with Z2 ECU and sensor and still nothing ...

Just with my PP7 ECU the A9 one , i got an 11 blink eror code should be IMA sensor but neither the car , neither the ECU got one...
Iknow it isn t the reason i ain t spark but wondering how come i could get that code for a wagon who don t have that sensor and neither the car which had the A9 engine ...

That s where i m now .. waiting for some spark in my head too to go on !!!!!
cheers guys for your help !
