Where is the Fuel injector fuse location 1991 Chevy van?

There isn't a single "fuel injector fuse" in a 1991 Chevy van. The fuel injectors are controlled by the engine control module (ECM), and the ECM itself is protected by several fuses and relays, not one single fuse dedicated solely to the injectors. A problem with the fuel injectors is usually indicated by other symptoms rather than a blown fuse.

To troubleshoot fuel injection problems, you should check:

* The main engine fuses and relays: These are usually located in the underhood fuse box and possibly an interior fuse panel. Consult your owner's manual for the specific locations and amperage ratings. Look for fuses related to the engine control system, fuel pump, and ignition.

* The fuel pump relay: This is crucial for the fuel pump which supplies fuel to the injectors.

* The fuel pump itself: A faulty fuel pump won't deliver fuel, even if the injectors are fine.

* The ECM: This is the brain of the fuel injection system. A faulty ECM can prevent the injectors from working correctly. ECM problems are generally not indicated by a blown fuse, but rather by various engine running problems.

Without knowing the specific engine in your 1991 Chevy van (e.g., 4.3L V6, 5.7L V8), it's impossible to give more precise locations. Your owner's manual is the best resource for the fuse and relay locations. If you don't have the manual, you can find a digital copy online.
