I bought an 89 civic lx around 2 months ago, it ran perfectly fine till one morning I turned the key and the car didn't turn over, no clicks nothing! I giggled the wiring under the dash and it turned on, a couple days later it happened again and I tried giggleing the wiring again and it wouldnt turn over, I checked my starter and it was fine, I blew a 50A fuse so I replaced it and when I tried turnin it on it turns over But won't start, my dad says its the fuel pump but my bro thinks its electrical problems cuz he thinks the car isn't getting enough battery to start. Does anyone know what could be the problem? Or have any ideas on what it could be
