Hi all
Any suggestions appreciated on this 1994 318.
It has a complete misfire on cylinders 2&4 No injector firing signal from the ecu on pin no 3.

I have good fuel pressure, good spark, injectors resistance check out ok, have swapped them around anyway, cam and crank signals good. Have eliminated the plugs and HT leads. Triggers to coil pack all look ok to my not so experienced eye as does secondary.
So I am thinking ecu as the owner says this problem started after he power washed the car, recovered for a while but then misfiring again.
I did open the ecu and it dosent look too good.
What is making me a little hesitant is, on start up, there is one or two firing events on pin 3 before it goes dead and I can force an output with the scanner.
So, have I missed something that is causing the ecu to shut off this pin
Any thoughts appreciated
Jim
PS apologies for the long story.
