The pulse is activated when your cranking and when the engine is running. In other words if you leave your key on "Run" and the engine is not running then for obvious reason the injectors are not pulsing. So there 2 conditions that tell the injectors to pump ... 1 in the crank and the other is when key is on and engine running ** There is also 1 inhibit ... the anti-theft if not satisfied will prevent or limit the injectors from staying on

WHY IT ONLY STARTS WITH HELP IS THE FUEL PUMP IS 1 TO 2 POUNDS LOW GM TAKE MORE TO START THAN TO RUN
