1998 accord wont start after turning it off and starting it almost immediately

Yes, and did you tune it up and do all 60 and 100k service points.
spark parts, and filters ? all ?
yes:
then its losing spark, check spark quality time number of cylinders.
the PCM will cut fuel if it (thinks?) that spark is bad, this feature (safety) is a spark read back path that tells the ECM/PCM that
spark is good.
so once spark is good, all 4 cylinder. (max) simple tests, (ask)
then its bad fueling, (more simple tests)

do you want us to guess, or explain the simple tests.
some like guessing.
top good guesses are:
1: bad fuel.
2: bad spark (never ever tuned up, this decade)
3: fuel filter packed, fuel pressure very low. or nil. or marginal.
4: wrong gas cap? causes low fuel pressure?

i check spark, then fuel.
to check fuel i fist check pressure, every time.
the squirt test only proves the pump has electr. power, nothing else. I use a real guage to do that., do you have tools and gauges and a volt meter? if not, its all just guessing.
