OK, so you have the first gen of the MPI system that they called EFI (1994-1996ish).
I think the fuel pressure is a clue - seems way too low. I think spec is 37 psi, so your 10psi key-on and 28 psi running sounds way too low. Weak fuel pump, vs faulty regulator? |
So I swappped high pressure pump from the good motor and it’s doing the same numbers

If I take the regulator hose off ibrake it jumps up to 30
|
What does the pressure read on the good motor?
|
Same numbers and on the motor acting up if I click the throttle forwards 2 times it will almost die out and comeback then start surging but if I give it for clicks to get to 1000 rpm it will just sit there and run after it sputters for a second
