Re: Brand new '89 YJ
 
Yes, I think so mostly because I am on this side of the computer.

I believe your coil is OK because of the flash on the timing light.

Using a test light or meter makes life a 'lot' easier.

When the key is in 'run', a test light should light up when hooked to
the coil positive.

The test light should stay lit when someone turns the key more to
'start' and the starter cranks.

If this happens, then put the test light on the negative side of the
coil and watch when someone cranks it. It should pulse or flicker.

If no pulsing, suspect the ignition module or coil pickup. There are
meter tests for the coil pickup. You need a multimeter for this. It is
easy.

Then you also should open the air filter, hold the choke open and hand
move the throttle linkage to watch the two squirts of gas that has to be
happening. If no gas, get back to us or toss a quarter cup of gas in
the carb and try it again to see what happens. If you get a roar,
suspect a blocked gas filter.

It's not the fuel filter, one of the first things we tried was throwing
some gas in the carb.

I'll try to run some more tests as soon as I get someone to help me.

So, based on what I think you're saying, I should suspect the ignition
module. My thinking here is the flash on the timing light indicates
that the ignition module probably isn't sending the right signals to the
coil in the 'start' position. Is this what you're thinking, Mike?

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.
