The car computer controls the signal. But check if all the connection to the fuel injectors didn't become loose.

If I could ask, how did you go about testing the pulse of the injectors. They should have positive current supplied full time with the key on, then negative current pulses during cranking. If you do not have a constant current, start checking fuses.
