Hi Ingo,

I have an oscilloscope to run a few test on and a good reference DME. When you mention looking at the injector current, I assume you want me to look at the output on the DME connector (something like pins 14 and 15). How would I hook up my oscilloscope to measure the pulse widths with the computer running. They are currents not voltages I am looking at correct?

I have been looking at schematics of the injectors circuit. It looks like the main components in it are the big diode (OF622), the darlington transister (T404), and the BJT (T403). There is the S400 chip, but that looks to also be tied to part of the ignition circuitry.

Would the possible delay in the injectors be caused by any of these components failing?
