Bzzzt 200 1990

To be fair, the "priming" was a byproduct of the electronic fuel relay introduced to the K-jet cars in 1978. It had no priming function then and doesn't now, but the 1-second buzz before the engine noise drowned it out was an extremely helpful tell to a technician troubleshooting.

When LH was introduced in 1982, and fuel pump control moved to the computer, the initial buzz was left out of the program for LH1.0, LH2.0, and LH2.2. Since it was easy to do in firmware, someone convinced Bosch to incorporate it for LH2.4 (and 3.1) beginning in 1989 for the 240. In practice, if the fuel pressure regulator and check valve function at all, fuel pressure is maxed out before the starter cranks the motor one revolution without need for the 1-second buzz.

The Art Collector's Wife:

A New York attorney representing a wealthy art collector called and asked to speak to his client. "Saul, I have some good news and, I have some bad news."

The art collector replied, "I've had an awful day; let's hear the good news first."

The lawyer said, "Well, I met with your wife today, and she informed me that she invested $5,000 in two pictures that she thinks will bring a minimum of $15-20million. I think she could be right."

Saul replied enthusiastically, "Well done! My wife is a brilliant businesswoman! You've just made my day. Now I know I can handle the bad news. What is it?"

The lawyer replied, "The pictures are of you with your secretary.”
