I know, I know, don't buy a 2000 Jeep Grand Cherokee. I bought it anyway, earlier this year for my sister in law to drive because she is taking care of our son. To date it has only had an issue with the started. Got that taken care of. Now the ASD relay is buzzing loudly. After some research, I found that we could put a jumper in, in place of the relay, and get it to run. A temporary solution, but a solution none the less.
Everything I have read points to the PCM being the most likely course. Has anyone dealt with this type of issue on the Grand Cherokee or Dodge in general? We swapped relays to see if the relay was bad, but there was no change in the condition. I'm seeing a myriad of solutions on the Jeep forums. PCM, bad crank position sensor, bad injector, a shorted wire, bad alternator, etc.
Turn key on, efan comes on, fuel pump constantly primes, and the ASD relay buzzes loudly (opening/closing). Once the jumper is in place, it runs just fine, of course because we have eliminated the "logic" circuit that opens/closes to say that there is a problem.
