If you think you've got the timing correct, then I'd probably look at the alternator. If the alternator isn't charging, then the engine will only run for a few seconds, give or take. It won't be long though. What it is, is that there's a diode inside the alternator that trips a relay to run the fuel pump. The fuel pump runs off of battery power only during cranking and then switches over to alternator power after starting. It's a safety feature so that if the engine over stalls, like in a wreck, the fuel pump won't keep pumping fuel and possibly making things worse.
