I had this problem last night with my 96 Isuzu Rodeo (same as Passport). The towing guy climbed asked me to be in park and engage the brakes. Then he climbed under the hood and banged the starter with a wrench while I tried starting the car. It started. Today it starts fine, but he told me to get it replaced. Usually a single click means the starter solenoid/relay switch is faulty. The whole starter does not have to be replaced due to a bad relay switch.
your battery is dead or the starter solenoid
I just had the very same thing happen to me yesterday. My truck had been making that noise for about 2 weeks and then yesterday I went to start my truck and it died on me. My husband put in a new battery and it started right back up! It's alive!! If it is not your battery then it could aslo be your starter, but have your battery checked first. I hope that this helped:)
The single click, that you hear when the starter switch is operated, is the solenoid making the high tension connection to the starter motor. If the starter motor doesn't turn over, you will need to check both the battery feed to the solenoid and the feed from the solenoid to the starter motor (this is typically a short length of braided cable). I have known this cable to corrode through. If it has, the easiest remedy, is to replace the entire starter motor.
there are two connections to the positive side of the battery, one to the starter, one to the accessories. some times corrosion get in between these two pieces. To correct this, i actual bought a battery with both positive connectors, (post and screw in) i hooked the starter up to one + part and the accessories to the other +. haven't had a problem since. Hope this helps
A single clonk type noise is a good sign. If you have a rapid clicking with dimming of the lights you have a bad battery. Make sure you have proper voltage/cranking amps before you make a decision.

The starter.
If it is a single click, the problem is either a loose battery cable or a faulty starter relay/solenoid. If the symptom is rapid clicking, the battery is probaly low.
If the battery and starter check out good and you are only getting a single click, the problem lies in the starter solenoid or relay. Not sure where the relay might be but the solenoid is usually where the positive battery from the starter connects to. There are at least two wires at the solenoid - the battery cable and a thin wire. check the remote starter solenoid usually monted on right side of engine bay
check the solenoid, and the starter.

starter soliniod
A fast rapid click is an indiction of a weak battery. A single click is an indication of a failed starter.
Multiple "clicks" check for a weak battery Check fr loose or corroded battery cables Single "click" Maybe a bad starter solenoid
A single click and no response from the starter usually indicates a faulty starter relay/solenoid switch. It could also be a loose connection on the battery cable.
A single click usually indicates a fault in the starter relay or solenoid - could also be a loose cable or wire.
The battery has gone "flat" and doesn't have enough voltage to activate the solenoid/starter relay and spin the starter, hence the single click and no spinning of the starter. Try charging the battery.
