Problem with a 92

The driver side bank of injectors are not firing. Does anyone know where the relays are????

Check your fuses on the right-hand side of the dash. Open the passenger door and you'll see the cover there. Now look for fuses INJ 1 and INJ 2, 10amp each.

There is not a relay, the FI's are fired by the ECM.

Swapped the fuses still same problem. Driver side injectors not firing. Verified with a noid light.
Passenger bank is fine.
Swapped in a known good ECM as well.

Trying to troubleshoot the no injector pulse on driver side

Well add me to the dummy list. I didn't swap the correct fuses.
The 20a inj1 fuse was blown. All fixed now!

My FSM calls for 10amp fuses for both injector banks and I just verified that on the car. You might want to have another look at that fuse block and see what it calls for.

We did. His FSM said 10A for the right bank, but oddly a 20A for the left bank.
