Three engineers
There are 3 engineers travelling in a car together. An electrical, a chemical, and a computer engineer. Suddenly the car comes to a halt at the roadside and will not restart.
The electrical engineer suggests stripping the electronics and tracing where the fault may be.
The computer engineer, not knowing much about anything, says "Why don't we close all the windows, get out, get back in, open all the windows again, and maybe that will work........"

They all look at each wondering what the problem is.
The chemical engineer, not knowing much about cars, suggests perhaps the fuel has emulsified causing a blockage somewhere.
