I think because the ecu isn't activating it, it wasn't showing.
I've traced all wires and done continuity etc all fine.
Manually activated ssv solenoid, works fine.

Prior point i raised early cars didnt have the code for ssv failure to operate which was why i took an age to find my issue...i swapped ecu popped a code a fix in 20 mins.I run this early ecu as its been mapped for 1100rpm.
I have a spare ecu set with immobilser and key that defo has the ssv software onit ...happy to send to you to try?
Looks like you have the switch but not the software for it in the ecu...

All you do is cable tie key in coil and hang down..use your key in barrel..just unplug coil reciever and plug in to mine.

Just thinking out loud. At 3750 rpm the primary and secondary injectors open, which is when my misfire happens.
Demand for fuel increases and if the pump isn't performing it will dip momentarily?
Also up the rev range it seems hit and miss some times.
I'm going to swap the pump out just in case

Boosted, I'd hold fire on sending me the ecu.

I've come to the conclusion that Quantum fuel pumps are sh!t. Please, any one reading this, do not buy this rubbish.

Old denso pump is in and no misfires or hesistation.
