Multipoint electronic fuel injection system with overlapping sequential injector actuation having a plurality of dual injector driver circuits (22-28) corresponding to an equivalent number of solenoid fuel injector pairs (L1, L5; ...; L4, L8) supplying fuel to an internal combustion engine, the injectors (L1-L8) being partitioned into two groups (L1-L4, L5-L8) with each pair having one injector from each group and by sequentially actuating the members of one group (L1-L4,) and then the members of the other (L5-L8), every injector (L1; ...; L8) being capable to be actuated for an extended portion of an injection cycle up to one full engine revolution; a bilevel select signal (SEL1; ...; SEL4) initiated with the actuation signal (EPP) is gated to each driver circuit (22; ...; 28) to enable each injector of a pair for one half of the sequencing period; associated with each driver circuit (22; ...; 28) is an independent pulse generator (14; ...; 20) which is additionally triggered in the sequence, the duration of the pulse width signals (PW1-PW4) from the pulse generators (14-20) being dependent on instantaneous engine operating parameters at the time of actuation; an inhibit feature for each pulse generator (14; ...; 20) is provided during desired acceleration or starting condition to extend the pulse width signal (PW1; ....; PW4) for the duration of time between two actuations; ; and provision is also made for banking the pulse width signals (PW1-PW4) to the driver circuits (22-28) during conditions when the engine may flood.
