98 mustang gt injectors not working (LH)
I have narrowed down my problem and apparently it is this. I know Spark is going into the cylinders but Injectors 2-4-7-8 are not spraying. Anyone know why it's not? Help is always appreciated.

All injectors receive +12 V via the same fuse, fuse #2 (20A) in the central junction box, and are operated by the PCM switching them to ground via MOSFETs. After the fuse the harness splits to power the bank 1 (cyls 1, 2, 3, 4) and bank 2 (cyls 5, 6, 7, 8). The "ground" side of the injector connections are all "home run" lines straight back to the PCM...
Are you certain it is the injectors you list, and not one entire bank?

Rent a noid light kit from your local auto parts store and make sure that the injectors are being commanded on. If they are not then its an electrical problem. If they are then it is either a fuel injector problem or a fuel rail problem. I doubt its the injectors because all of them wouldn’t cut out at once. But that bank’s fuel rail could be restricted somehow not allowing fuel to the injectors.
Good luck...
