Thanks for any help you are willing to give.

No power to injectors where should I look --- all fuses are good.

Year and model of the car? LH injection 700 series? First guess is radio suppression relay; probably located on one shock tower or the other; silicone sealed black boxed relay (maybe one of two; one for the fan one for the injectors) Open and resolder the circuit board. If you have two identical relays swap one for the other and try starting again. Resolder both relays to insure function over time.

Thanks for the reply.
