is this this s DIY question or ? just a request for wild guessing.
Ill assume its a real DIY. ? do tell.
what is a jumper box to house. ?????????????????
first off, you need to say,
it
cranks robustly but does not start or not.
does it crank? if yes, why buy a starter?
no car starts unless cranked. (mine push starts and gravity starts)
but I bet yours is a A/T tranny , automatic.?
so does it crank.?
?
lets pretend, it cranks perfectly.
and really is a no start (confusing your replacing a starter )
this jeep , like most from 1993 have the ASD relay.
THE ASD relay must close to start the engine.
The ASD relay must close, and if spark , and up to 7 other things
are good, then it will stay closed, if not it drops out. KILLING starts.
that is what it does, so watch the ASD while cranking, what does it do>???????????

now I will do NO CRANK.
and the
funny house box thing, (a battery charger? or what i cant guess)
no cranks are caused.
By bad shifter, switch.
this is called the key line.
so i hot wire the starter solenoid, (remove tiny wire first to it)
ask how to do this.... its not hard. (mostly but some cars have shields making it harder today)
and it dont crank ! NOW? , then bad battery,starter bad, cables or seized engine. (turn engine by hand ,ok? to spin? by hand?)
and it does crank. then
bad key line is reason.
easy huh? just one hot wire step and bam, problem cut in half.
i then try to crank in neutral, bam it cranks. and starts.
bad
PRNLD switch.
or i just wiggle the shifter, bam, it cranks
or i wiggle the key switch funny in crank position and bam it cranks
bad key switch.
last, pretend the starter fails the hot wire above.
i hit it with a hammer, bam it cranks now.
we can do all that with a voltmeter easy,
ask.

see hot to solve no cranks on most cars.
other simular failures.
battery dies after parked.?
charge light (dash) on , driving? or idling, bingo, dead battery.
one more , car cranks but will not start for longer than 2 seconds
ASD action
but you failed to notice the Immobilizer lamp glowing wrongly.
my last answer. the
funny house thing is a battery charger
and if you leave it charging long enough car cranks.
bingo?.?????
if yes, then the battery is DEAD and is DISCHARGED.
it discharged because you or something is left running, in car.
see phantom drains here.
the reason the car jump failed is you didnt give it enough time.
a very bad car battery can swamp the donor cars power source.
(and easy with cheap jumper cables.)
here is what you did wrong.
car is rested, it wont crank
you open the hood.
and check the batteryvoltage with a volt meter.
it reads 12.6vdc rested. good, it should crank ok, (but my not)
or it reads 12v, its discharged, so charge it to 12.6v and try again.

- won't crank?
- battery discharges overnight.?
- won't start but cranks ok.?
- charge light stuck on.? running.?
