BB, 8 times out of 10 when both 51 & 52 (injector codes) appear, it is from low fuel pressure either from the pump going south and/or the black canister filter above the pump cracking and or plugging up.

It is possible but not likely that both injector harnesses are bad .

Last is that the ECM (power module) is going away . I would start with the cheap and easy and check the fuel pressure.
