Coil Pack's all fire at same time....

Post by hoopla14 » Mon Apr 16, 2018 12:50 pm

H22
1992 eg
s300
cpr kit
RED LIGHT comes on
GREEN LIGHT COMES on
sync light comes on and flashes.
Car barely starts and runs very ruff.

Remove coilpacks and spark plugs and ground to chassis to make sure there is spark.....turn car over all 4 coil packs fire at the same time. This happens whether yellow red wire is hookup up to a21 or a22 (directions show A22 but then at ecu picture says A21)

Should all 4 coils fire at the same time?

Hooked everything up wth stock distributor and plug wires and engine runs fine. Pull plug wires (stock) and hook spark plugs in and turn car over, spark is 1-3-4-2-1-4-3-2 etc.....

Anyone shed some light??

Have you uploaded to the ECU with the CPR options enabled? IT sounds like the ECU is in limp mode and batch firing the spark plugs instead of sequentially firing.

Can you show pictures of where and how you have everything wired?

Yes changed in s300 to coil on plug set up.

Tried another s300 ecu. Only thing I haven't done is change wiring.....

Will get pics tomorrow.

Try your CPR box on another vehicle that already has a CPR installed and running.
