you mention about disableing the fuel system but you didn't mention about disableing the ignition system unless you are disableing it when you remove the clip that is on the coil. i was told to step and hold onto the gas pedal while cranking the engine over when you begin and you should only give it four puffs to see reading or does it not matter.
