Hi, title says it all. My K75 has been having intermittent issues and now has decided to be dead. Testing described below was with power on and cranking the engine. The starter does work correctly. Checked the power to the fuel pump at the connector just outside the tank. No power. Just to confirm believe this was the Yellow and brown lines. Though none of the lines showed power. Checked that there was no spark by two methods. 1.) pulled the spark plug connected the spark line and grounded the side of the spark plug, then cranked the engine. 2.)use of a timing light. Hooked the timing light over #3 spark wire and cranked the engine while pressing on the timing light's switch. Both methods indicated no spark.
So I've been going through Bert's diagnostic flow chart but haven't seen what would cause both the fuel pump and spark plug to malfunction.
Any suggestions?
best regards

P.S. I've been assuming that Bert's notes on K100 also apply to the K75.
