Question about 1989 Honda CRX

2 Answers

1989 Honda CRX won't start after a short trip.

My 1989 Honda CRX starts when cold, but after a short trip, like to the grocery store, it cranks over, but no fire. I've noticed if I don't hear the fuel pump momentarily make a noise after turning the ignition key on, I might as well save battery and wait several minutes. Sometimes, up to 30 minutes. I believe there have even been times when I hear what I've presumed to be the fuel pump " come alive noise", it still won't start for a while. I called a parts store to inquire about a fuel pump relay, and they said they have no part listed like that. Hmmmmmm.

    I have a 88 Honda Crx with a 96 civic D16y7 carb engine and it is doing the same thing. About 70% if the time when I go to get gas then try to start my car back, it wont start..Sometimes it wont start when I leave it parked over night...I looked at the relay..opened it up and it looks brand new all the soder joints look good. So Im guessing it has something to do with Vapor lock or the pressure in the tank Might even be the "pressure regulator"? Im just guessing but Im going to get another gas lid and see if that fixes it.

    I have the same problem. I bought that MAIN ASSEMBLY RELAY from honda and it worked for about a month or two. Then i thought it was the fuel pump, so I decided to replace that since I was replacing the gas tank. Im still having that problem, but the car does start when you jump it. :) !! Someone told me that it might be the ignition starter switch, so i will be replacing that later this week. this SUCKS!

Easy one.This is a common problem on 88-91 Civics and CRX's.Check your main relay under the drivers side dash.It provides power to the ECU,fuel pump,and injectors.Its a squarish box with a single plug going into it held on by one 10 mm bolt.The solder joints break down over time and cause the condition you're having.You can pry off the plastic cover and resolder the joints if you are handy with a soldering iron,or just ask for a main relay at Autozone,etc.

If you're replacing the relay bring in the old one to the shop to match it up; they're are a couple different styles

What is an error code 8


TDC (Top Dead Center) position/crank angle sensor or circuit Problem. That's what Honda calls it. Part stores will call it a CRANK POSITION SENSOR. P.S. The Sensor itself is probably going bad.

ECU Code 4 on 1989 Honda CRX si


No one can tell you what other problems you would have, they would be playing GOD. Anyway the crank angle sensor is built into the distributor and you should change it asap. An option is to get one from a junk/used car yard. If you wanted it re-manufactured Autozone will have it with lifetime warranty.
