really strange fault or faults you have. (sounds like i am imitating Yoda)
if you have flippers and F4 is ok then you should have at least the left and right slingshots.
check F1, F2A, F2C and F3.
are all the flashers working of just some?
one last thing i need you to do is when in coil test take note if any flashers are flashing when the test display shows a solenoid should be firing.
