Re: Brand new '89 YJ
Did the previous owner give any indication of problems?
I am more inclined to think dirty connection.
I would next if solo try running a booster cable from the battery
negative to the body of the Jeep and see what happens.

Re: Brand new '89 YJ
The PO told us that the starter had died. This is most definitely not
true, so it's kinda hard to believe anything he told us. Of course,
it's been sitting for three years.
My pop's home, it appears that we do indeed have a multimeter.

Re: Brand new '89 YJ
Cool, try the booster cable to the body test anyway, that has started an
amazing number of vehicles that I know of, especially rust belt ones...
You also need to verify those gas jets into the carb when you hit the
throttle!
An induction timing light can 'Really' lie and show no flash if a 258
engine isn't getting gas. It is strange but very true. I, for one of
many have chased spark parts all over only to find out the timing light
I used as a benchmark wouldn't light with no gas present.
Had one with no light flash on cylinder 1 to 3 with a really bad idle
and after swapping 'every' electrical part we figured out the damn carb
had a blocked idle tube, which by the way is really common and easy to fix.

Re: Brand new '89 YJ
I'll check for the gas, but if that were the problem wouldn't it have
started at least for a second when we put gas in the carb?
I did spray the carb down with tb cleaner, but didn't really give it a
really thorough cleaning, which I'll do soon. (by the way, is there a
difference between carb cleaner and TB cleaner?)
With the cable to body test, I'm essentially checking to see if my
ground is screwed up?
Sorry for so many questions for explanations, but if I can understand
the theory behind what you're telling me to check, I'll be better able
to make sure I'm doing everything right - and next time, I won't have to
bother you.
As always, thanks a lot.
