Electircal Help Needed 93 Civic DX wont start. - Honda-Tech

Niskyspy · 04-19-2008, 08:28 AM

So here's what happened over the last couple of days:

Day 1) I get out in the morning to go to work. Get into my car, crank the car (it starts then dies in 2 sec). After that it would only crank but wouldn't start.
Same day after work I got Haynes manual out and figured out that my fuel pump isn't getting any juice. After some more trouble shooting I found a maybe broken relay (as I found out its a usual thing for 92-97 Civic and 94-96 tegs).

Day 2) Found a website that showed how to fix the relay by re soldering the tips and putting new solder on. The car worked fine for a day

Day 3) Same thing all over, no juice to fuel pump so I tried fixing the relay but it didn't help so I guessed that the relay is busted.

Day 4) Went to Keeler honda got a new relay $64+tax got a ride to work (thats where the car died). Put the new relay, the car started up and everything was working fine drove it around (got some fuel).

Day 4) Got out of work go to my car put the key in, dont hear the fuel pump turn on, car doesn't start. So I stayed in the parking lot had my friend and my Dad come help and bring tools, manual. Worked on the car 8pm-11pm to no avail.
Checked all the Fuses (cabin, engine)
Checked the Voltage at the relay, it gives me 1.5V but it should be around 12V
Hot wired the fuel pump which works
Tried starting the car with hot wired fuel pump and relay in (car wouldn't start)

DAY5) Took the dash and everything out so wiring and fuse panel is more visible. Did some more trouble shooting and found that prong #5 on the relay is not getting 12V but only 1.5V when we unplugged a connector under the hood on the left the voltage jumped to 3.6V. My honda manual it says that the voltage at #5 should be 12V. At one point the car started up and ran (I did check's and the #5 got 12V) I took it for a 10 min spin and it stalled and wouldn't start again. So I checked the voltage again and it was back to 1.5V. I checked all the fuses that go to Main Relay and they are all fine.

DAY6 Today) I have no clue on what I'll be doing to the car today. I am getting so pissed that I might just run 2 switches for ing and pump and run the car that way.

So please if you might know what this is please post because I am starting to go low on the things to check/troubleshoot.

Thank you

Bad ignition switch?

Totally sounds like the ignition switch.. Agree with the above.. Good Luck and let us know if it works!

eh spent like 6 hours under, removed the dash, took out my Multi Meter and started testing the ignition wires and all the wires that went to the relay. I pinned the problem yellow/black wire that goes from IGN switch to FuseBox got screwed up where it comes out of fuse panel and goes to the Main Relay so I jumped a wire from 15A fuse (12V from IGN switch) to the relay Black/Yellow PIN#5 and the car started up and works fine.
Eh I guess I have a lemon civic because I am having lots of difficulties with it.
