If you're experiencing fuel pump issues, the problem likely lies elsewhere:
* Fuel pump relay: This is a more common point of failure and can be easily replaced. You'll need to consult your owner's manual or a repair manual to locate the relay.
* Blown fuse: Check the fuse box for a blown fuse related to the fuel pump.
* Fuel pump itself: The pump might have failed and needs replacing. This is a more involved repair usually requiring dropping the fuel tank.
* Wiring issues: A short circuit or other wiring problem can prevent the fuel pump from working. This requires tracing the wiring harness.
* PCM issue: In rare cases, the PCM might be faulty, but this is less likely than the other problems listed above.
Before attempting any repairs, it's highly recommended to consult a repair manual specific to your 1997 Jeep Grand Cherokee's engine (e.g., 4.0L, 5.2L, 5.9L) to correctly identify and access the components mentioned above. Attempting repairs without proper knowledge can be dangerous.
