ZX9 B HELP - Won't fire on all 4
As above
Fitted this to my Westfield and now have an issue.
It will FIRE on cylinders 1-4
Won't fire on 2-3
We have fitted the 100 ohm resistor for the ignition
When removed the engine will NOT turn over.
When fitted we get the above result - 1,4 fire but 2,3 don't.
Tried another ECU, Crank sensor
Re wired 2,3 coils but no joy
Swapped the coils over from 1,4 to 2,3 and 2,3 WILL FIRE and 1,4 don't.
Going to recheck the earths and change the resistor - It was an ebay resistor so if its incorrect ohms i assume it won't fire all 4.
Cylinders 2,3 are controlled by the ecu.
Any help or input would be hugely appreciated.

Looks like you either have a Diego coil pack (if it has one ) or one of the feeds to the coil pack or could is cracked. As far as I am aware, If it is
a coil pack with three wires one will be live 12v the other two will make a circuit when cranking. Check this out first, if you are getting feed to
both wires then it is the coil pack, if not it is the wire not getting the feed.

This is the type I have mate.

Don't know much about the zx9 but if it has two of these, and they look like they have two connectors, remove these, put a multimeter across the
connected wires, crank the engine and see if you get volts (may go up and down as it is sending a singnal in time with the engine cranking), do this
for both. If both the same then feeds are ok, and it is the coil pack.
But as you said, if you swap the packs then the other two cylinders fire, this points to a dead coil pack.

Sorry what I meant was if we swap the wiring for the coil packs.
The coil packs are 100% OK buddy.
It's something stupid but so frustrating.

It won't be the resistor. If the resistor was faulty it wouldn't run at all.

Most likely an harness issue. You need to continuity check from the ignition unit connector to the coil inputs to prove the harness.

Sounds like the ECU's coil driver power transistor is blown or circuit board fault.
Coils are ground side switched identify the the coil control wire at the ECU connector and back probe it with a T pin, connect a test light to
battery negative touch it with the business end of the test light and if the ECU driver is OK you should see glow and it will it pulse when the
engine is cranked.

He's swapped the ECU if you read above.

Check any multi pin plugs in the circuit, ive known them push connectors out as you plug them together, the Japanese plugs fit so tight you dont
notice...

Are you getting +12v on one of the coil primary (AKA low tension) connections with the ignition switched on? Preferably use a test light (e.g. 21watt
bulb) rather than a meter to rule out any high resistances which won't show up if you just use a multimeter to measure voltage.
If that's ok then check continuity between the other primary side connector and the appropriate pin on the ECU connector.
