All the injector leads are connected in paralell, they should all show identical voltages, and should both show close to 12V if you have at least 1 injector coil still attached.
Seems you have a faulty loom.

Ah, that might be the problem. You've just jogged my memory that I had to throw out a pesky field mouse from BOTH of my Volvos. Chucked him out of the bonnet lining on the 940 and the cheeky s*d moved into the V70.
I left the linngs out and then had to suffer clouds of steam from water evaporating on the bonnet when it rained and I was stopped in traffic.
Will investigate with a torch. He/She might be back as a result of the lockdown.
Just to clarify - should both injector plug wires show the same Voltage when grounding them via the Voltmeter or at least the same Voltages for each separate lead wire IYSWIM?
