Random engine dying and non-starting 1990 Honda Civic?

I have a 1990 Honda Civic with an automatic.
It randomly will shut off while driving.
It also randomly will not start properly, it will turn over and start fine but then die right away.
Both issues are random, sometimes it's fine and will drive for a month no problem, other times I have to stop three times in a mile because it keeps dying. Sometimes after it dies it won't start again before the battery dies and I have to get it jump started.
I have fuel and spark.

Could it be the main relay has a connection that is fractured and randomly connects and disconnects? Or something else?

Re-solder or replace the relay and just replace the whole distributor. A whole new distributor online is about 65 bucks and it comes with a new coil, module, cam sensor, crank sensor, cap, rotor. - bargain of the century and usually fixes this common problem.

Have to run tests while its acting up. Could be fuel pump, pgmfi main relay, or distributor going bad those are the 3 big failure items

That is not typical for the main relay, which normally does not act up when driving, just when starting (although the start and die could possibly be it). Top suspect is the ignition switch. If the warning lights (oil, check engine, battery) are not on when the engine dies it is the ignition switch.

  • Why do motorcycle engines have a random displacment? The ninja 250 was technically 248cc. The Honda cbr300 is 286cc. There are plently of other examples too. I've never seen a bike whose engine is actually what they advertise

  • Honda magna random idle issue? So I just got a 1999 Honda magna 750. It starts and runs great, but it has this random issue when idling. So while idling it'll idle normal where I've set it, then for about 2 seconds the idle will jump up about 1-2k rpm then it'll go back to idling normal. It does this while in neutral as well as when I pull the clutch and let off the throttle and coast to a stop. What could be the cause of this? Abd what can I do to fix this?
