Hello

I am new here from the UK and hoping that someone can advise on fitting the standalone 2001 on Eunos BP6D ECU to a standard factory immobilised 1.8 VVT MX5/Miata.
We have bypassed the starter relay, so immobiliser not required to energise starter but struggling with Fuel Pump operation.
I believe the Eunos has no Fuel Pump relay, so had thought that bypassing that relay, so that switched live constantly fed to the Fuel Pump would have worked but it hasn't.
With a head of fuel, the engine will run briefly but it seems the pump is not running as I expected it to.
Can anyone please put me out of my misery on this.
