I have a no start on the 745GL. It has no spark, the tach does not move when cranking and the fuel pump is not run when cranking. This is I assume because of no pulses to the FI ECU.
ANy way to test a flywheel sensor with a VOM? Any way to test the coil/power stage assy.?
Also have a scope, but really don't want to haul it out to the driveway.

thanks,
