No significant change, when swapping the relay's

I found another intersting thing.
If i remove the wiring from the injector from the second cylinder
the engin starts and runs, only on 3 cylinders but it runs
Then reconect and the problems stays away for a while

Any new thoughts ?

Only with that one injector?

I would try swapping the wires between that and another injector and see
if the issue follows the wire or the injector. They're batch fire so any
injector can be plugged into any of the four connectors and there should
be no difference. You might have an injector with an intermittent short.

So it could be the number 2 injector, because that one i disconnect.
I remebered that "trick" from the AA guy.
He wanted to messure the voltage on the injector and ask to start, than the
engine start running also.
After disconneting that wire the engine will start and run for a while.

Are there any known cases for the intermittent short off the injectors ?
Any tips to locate that fault ?
