It sounds more like a fuel problem to me then a bad coil or spark ign the spark should be blue but its hard to see in daylight
You say you rebuilt the carb are you sure your main mixture jets are at least 2 to 3 turns out off the stops .
Try pouring fuel down the barrel fill the float bowl if it runs then dies its fuel don't let it catch unfire you should have 45 sec. of run time then adjust the the mixture screws 2 turns is base but when its is running good turn them in 1 at a time and give it 30 sec. to adjust until it starts to stumble then back it out a 1/4 two 1/2 turn then repeat on bank 2
Have you checked the HT leads? The main lead from the coil - take off a spark plug lead and plug that into the coil insted and see if you can get it to spark to the engine, if it will spark with this lead then the main lead is bust.
also...There is a condenser on the ignition, it prevents the spark from going anywhere but the plugs, if this has failed you will have a weak intermittent spark - heres what it should look like (attached to the distributor or very close to it) - http://www.rockauto.com/catalog/raframecatalog.php?catalog=233&partnum=84UX&a=UK233-84UX - click the "i" button to get a bigger pic - make sure yours is properly connected before you get a new one.
It's incredibly cheap so may as well replace it + its 21 years old and counting and probably the only original part of the ignition.
Is the coil connected to the ditributor? did you knock any connections off in the process? Does it turn over but not fire? do you have spark at the plugs? Are you sure of cylinder location in respect to firing order? Did you-and check this first as with any elec. problems-blow a fuse in the ignition circuit? good luck!
i have a 98 and it has a distributor but it could be a fuel issue more than a spark if you have a fuel pressure gauge and check it.should be above 30 psi to me it sounds like a fuel pump thats bad
ive changed spark plugs wires distributer cap roter button tps coil timming chain
