--START-UP CONTROL FOR FUEL INJECTION SYSTEM-- ABSTRACT OF THE DISCLOSURE A fuel injection system for a multi-cylinder engine includes means for generating a sequence of pulses during each cycle of the engine. These pulses trigger variable width pulse generators, sensitive to the engine operating parameters. The variable width pulses are pro- vided to the injectors so that each ejector fires once during an engine cycle and their firing times are spaced over the cycle. During start-up, the pulse widths are diminished and all of the injectors are fired each time the sequencing circuitry provides an output pulse. The total charge provided to each cylinder is thus distributed over the engine cycle, insuring the presence of the proper quantity of fuel for optimum flammability to achieve start- up of the engine in at least one of the cylinders.
