1997 Honda Accord LX I4 non VTEC Won't Stay running for more than 1 second.
Hi! Thanks for all your help in advance ;)
Anyway, a little background.. I've got a 1997 Honda Accord LX coupe with the non-vtec 4 cyl motor. It's got around 170k miles. It just had a new clutch and used tranny put in 2 months ago. When the mechanic did it, he ruined the ending temp sensor and messed up another sensor on the coolant line under the hood, so the car throws a code [forgot which] and the CEL light is on. The car is hard to start when cold because the damaged sensor is caused the computer to go in to closed loop mode with a coolant temp of 180 degrees. Anyway, it's been like that for 2 months and yesterday I was going to go to the mechanic and get the sensor replace.
Also, the ignition switch is wonky, aparently a common problem. Occasionally, the car will just straight up die while driving after hitting a bump or hitting the keys with my knee. The car always starts right back up without even needing to pull over. Also sometimes when I take the key out the car keeps beeping as if the key was still in the ignition and I have to put the key back in the ignition and remove it again to get the beep to stop.
Anyway, here's my problem...
I drove around for work all morning, no problem. I ran in to the bank, cashed a check, and came out to a car that wouldn't start. Or more specifically, it starts and runs for about 1 second and then dies.
I then notice that I don't hear the fuel pump when turning the key to ON.
I check the fuel pump fuse, and replace it for good measure. No start.
Then I pulled the main relay. It smelled like ozone, and some of the solder points on the circuit board appeared to be burned. So I went to the junk yard and pulled 3 separate Accord main relays. I tried them all to no avail, same result.
I then noticed that with the new relay installed, or with pins 5 & 7 jumpered on the harness if I turn the key to START without pushing the clutch, I can hear the fuel pump engage FOR SURE. I even pulled the fuel pump fuse and tried, no sound. Fuse back in, I can hear the pump. But only when they key is turned all the way forward to START, and it runs for a few second and then stops with a relay click if I hold the key forward to START. When I put the key to ON, I can't hear the fuel pump kick in.
I am going to check the MAP sensor harness voltage shortly to test the computer...
And that's where I'm at. My car is behind the bank, and needs to go away by Monday. I am REALLY trying to avoid a tow here.. So any help would be awesome!
I read somewhere that it's likely the ignition starter switch? That's a common problem on this car and when it fails it can cause the symptom of running for 1 second and dying when the key is released from START... I don't want to spend the $50 and the time and trouble if I don't need to though..
