The ECU aka computer.. As long as it is EFI, carbureted cars are controlled by suction...
I believe 89 there where both cars.. Carb'ed and EFI1988 Ford Festiva "Sonic" BPT g25mr MS2 standalone ecu, FOTY '11, Best Beater FMV, Fan Favorite FMVI

the injectors on all EFI festys are saturated (meaning that they always see 12vdc, the ECM completes the circuit and controls the length of time open.) they also bank fire (1+3 fire and 2+4 fire at the same time)Trees aren't kind to me...
currently: 2 88Ls (Scrappy and Jersey), 88LX, 90L(Pepe), 91L, 91GL (Skippy) 93 GL Sport (the Mighty Favakk), 94 (Bruce) & 95 Aspire SEs, 97 Aspire (The Joker),
94 Justy 4WD, 87 Fiero GT, plus 2 parts cars. That's my fleet.

thanks,, now i have a basis of where to start to figure out why they arent pulsingComment

as they're saturated, you wont see a +12v pulse, you'll have to read a ground pulse from the ecu.
my guess is they're not getting +12v or the ecu is shot.-Zack
