Good morning, I have a 2000 grand voyager. Over the weekend I was driving as normal and when I parked and went back to drive my van hesitated to start when i turned the key, I thought it may be the battery cables so i jiggled it and she started, later on same thing but this time nothing. I have lights horn etc, I gave it a jump and still nothing. When i turn the key i get the hum and a click and nuttin else. Im not getting the usual click click click for a stater problem or the alt problem noise. I let it over nite went back and she started fine. I changed the starter relay and the same thing happening, she would start fine, i would drive around come back and try to drive again and nuttin. if i leave it overnite she would start in the morning. I am baffled, any suggestions?

 

need to know engine size
when it wont start next time hit the starter then see if it will start up.

 

3.3 engine

 

First make sure the "hum and a click" is coming from the starter relay or the starter. If that's the case it eliminates the control side of the relay meaning, the PCM, TRS, security system, ignition switch and all it's associated wiring. That leaves the output side of the relay meaning the battery, battery cables, starter and wiring.

 

that sounds good to me thank you. To be continued...............
