Hi. Engine revs up and down with the auto shutdown and fuel pump relays clicking fast continuously and check engine light flashes in sync with the relay. sometimes the relays keep clicking when ignition is shut off so I have to disconnect the battery
to stop them from clicking. When driving car it's like the engine is being turned off and on continuously causing jerking motions similar to a real bad engine miss.
JA: Does the light stay on, or does it blink?
Customer: It blinks on and off in union with the relays, then goes off when the relays quit clicking after about 20 minutes or so of driving
JA: What is the model/year of your Dodge?
Customer: 1998 grand caravan with 3.3 engine
JA: Are you fixing your Grand Caravan yourself? What have you tried so far?
Customer: Changed whole relay box with one out of a junkyard and seperated wireing harness wires going to relay box
JA: Anything else you want the mechanic to know before I connect you?
Customer: once in a while when the gauges totally quit working the car runs fine. otherwise the gauges go off and on in sync with as engine missfires
