I have an 89 honda civic lx 1.5L 5-sp. The car was running great until one day I was driving along around 60mph when the car sputter and lost power as if running out of fuel. I pulled over and the engine sputtered a little more but then was fine. This happened several more times over the course of a week or so until one day, the engine stalled at a stop sign and would not restart. After several hours my dad and I returned to tow the car, but it restarted and drove home fine. Reluctant to drive it on my 80 mile round trip commute anymore, I only drove the car on short trips around town. One day I drove the car 3 miles or so and it stalled on me while pulling away from a stop sign. I walked home and returned a few hours later. The car started and drove fine back home. Not wanting to be stranded anymore, I stopped driving it altogether. I would start the car from time to time and let it warm up. Soon after doing this a few times, the engine would stall more quickly each time until finally it would start and stall right away. The car has 371K but was running great, getting 37-39 mpg, burned no oil, when all this started.Ive replaced the coil, ignitor, plugs,wires,fuel filter. Also a few years ago the main relay and fuel pump were replaced, but with after market parts. Please, someone help!
