Injector voltage



I’m having trouble with a F4rt

It’s just dying and cutting out when you rev it up or go to pull away

It’s got 4 new coils

I’ve removed one injector plug at a time when it’s running and I’ve got 14v on one wire and 2.5v on the other wire

Is this normal ? I was only expecting 14v on one wire

That sounds right.

The 14v will be the power and the other will be the 0-5v reference that's sent to and from the ECU.

Cutting out when revving sounds like a sensor issue.

Possibly the crank sensor.

I’ve tried a new crank sensor and it’s still the same to be honest

Is there anything else worth changing ?

It will sit and rev standing still but when you go to pull away it just pretty much dies

Also seems to be a bit better when the engines first started from cold
