"Before starting, make sure to:
* Have two fully charged fire extinguishers on hand,
* Check the entire fuel system, from the tank to the injectors and back, for leaks while running the fuel pump. DO NOT attempt to start the engine if there are ANY leaks whatsoever. Fix any leaks before proceeding.
* Check that the fuel pressure is appropriate for your system (usually about 42-45 psi for port injection when not running, usually around 12-15 psi for throttle body systems).
* Verify that you have powered your MegaSquirt form a +12V source that will supply current while cranking. Many reported problems with MegaSquirt have been traced to power sources that are connected in “run” but not while cranking. Check your vehicle wiring diagrams if you are not sure."
