I have very little electrical knowledge and it seems like a few of you know what your talking about so im hoping to get some step by step help. My 90 civic dx hatchback wont start. It used to be an intermittent problem, on hot days, after short trips, or just randomly. But now it wont start at all. i replaced the main relay, it ran for 2 days then stopped again. When i finally got it running again as soon as i turned the corner it died on me but i was able to get it started again before it came to a stop. the fuel pump itself tested good and the main relay is new and clicking. The engine light goes out like normal, the ecm only flashes 1 time and the board looks good. All battery cables are new and so is the main ground. So what should my next step be?? All i have is an ohm meter with maybe a foot of wire, and a test light. If someone can be patient enough to walk me through this maybe with pictures or a diagram i would greatly appreciate it because this rust bucket is my only vehicle and i lost my job because of it ( also where can i find these troubleshooting flowcharts?? )

 

Can you hear the fuel pump prime when you turn the key to the on pisition?

 

No, it isnt priming

 

Ok, its always had in intermittent starting issue since ive had it, about 2 years. Then it finally just stopped working. Took the fuel pump out and tested it, it worked. So i put it back in, and bought a new main relay and put it in, the car started right up, sputtered awhile then died. Probably from the fuel pump being undone. then it started up and ran fine with no problems for 2 days, then i went around a corner and my car dies but i turned the ignition and it started again before the car came to a stop and i made it home. The next day, it wouldnt start. No fuel pump sounds.
