Sup fellas,

History: Bought car early Feb. Have put over 8000 miles no car with no issue. Prior to problem, car would not start on first try.
I recently replaced the cap/rotor on a 90 Civic Lx 240k. After replacing parts, car started then stalled on the highway shortly. I have then tested the coil which came to be bad. The coil was replaced, the car started.
Next day after car wash, the car would not start. Tested the ignitor and concluded was bad. Replaced the ignitor but the car still would not start. I ended up taking it to a trusted mechanic and he replaced the main relay and the car started. Drove the car home and it ran fine with no hint of issue.
Next morning during test drive, car started to buck (rpm needle started to jump around) can feel the car is misfiring. I'm totally confused at this point. Can anyone point me to the right direction? what else can i check? Thanks for all the help guys

 

did you wash the engine at the car wash? if so, could have moisture in the distributor

 

This.

I'd check the distributor mainly.

 

normal car wash at home. There's no sign of any moisture in distributor. The ignition coil, ignitor, cap/rotor were replaced with new ones. With all the readings, I'm starting to think that the fuel pump might have gone bad...battery, starter, alternator all test ok. What else should I check?

Thanks fellow 4dr! Been to that site, read that thing about dozen times. The only thing that has not been inspect or change is the fuel pump, so just looking for reassurance or any advice
