Question about 2001 Isuzu Rodeo
Okay, so it clicks when trying to start which means it is not getting enough power from the battery, hence when you jump it starts. Most likely your alternator is not putting out enough juice to charge battery. I would check the output from alternator, ohm/volt meter if you have one, if not they are relatively cheap. Most parts store's O'Reileys is one that I frequent, will let you use a scanner to plug in while you are at the store which may show a code to the problem. Probably the regulator is bad, not positive but I believe it is internal in alternator. Hope this helps.

I had the same problem as you. Thought it was starter or battery,,,it was neither. I kid you not, I figure this out for myself and problem solved. I did not have the tailgate window locked and it took at least 30 attempts to start. When I locked the tailgate opener located on the far left of dashboard, never a problem,,,, I pulled out the operator's manual/remote control/vehicle security system manual and to my surprise it confirmed. Here is the exact quote from manual "While armed, the system is triggered when a door or the tailgate window is opened. When triggered, the vehicle's horn sounds, and the exterior and interior lights flash. PERHAPS, MORE IMPORTANTLY, THE VEHICLE'S STARTER IS DISABLED AT THE SAME TIME, PREVENTING ENGINE START!!!" Please let me know if this solves your problem or you already went there..

SOURCE: My 1999 isuzu rodeo wont start.
check all your connections to your alternator,starter and your battery But you you are hearing the starter "click" but not engage..try tapping on the starter with a hammer if it is easy to get to..this some and sometimes does work..but your starter solenoid can be bad..the starter can be bad..igntion module a number of possibilities..goto your local parts store or public library and purchase a repair manual or check one out at the library

the clicking is the start relay which u don't hear unless the starter doesn't work, u have a defective starter solenoid, the internal contacts are burned, this is a NipponDenso style starter and they all have this same problem, u can replace the starter, replace the starter solenoid or replace the copper contacts in side the solenoid for around $12.00 USD

Dirty terminals, happens all the time. Did you have the battery tested? Or just know it's OK? Did you check the water? How about the electrolytes? Get the terminals cleaned off with a wire brush, and scrape the insides, make sure they are tight. I have replaced more batteries this week, must be the weather. One was stone dead, 5 volts and still started the car?? Couldn't believe it, good car. The other 2 were dead with 12+ volts but wouldn't start anything, both got new terminals, and both got cleaned up. NO problems. Check it out. Lastly, the solenoid in the starter could be bad if everything else checks out, whack it with a hammer while turning the key, if it jumps, you found it.
