If you know how to solder stuff, you don't even have to replace it. I re-soldered mine and it works perfectly now. I have horribly shaky hands, too - the contact points are huge so you don't have to be very good at soldering. =) Save yourself some money! Here's a nice big guide:

Acura Main Relay location and removal procedures.

  • 1986-89 INTEGRA
  • 1990-93 INTEGRA #39400-SH3-003 RELAY (RZ-0063)

  • 1991-93 LEGEND (rz-0105)
  • VIGOR (behind the left front kick panel)
The main relay is located behind left side of the dash and above and behind the fusebox and above the hood release. The First generation Legend main relay location is between the steering column and the fuse box. It's deep in there. There was a little difficulty drawing the relay so it's actually very deep in there. There is a device (a relay) blocking the main relay. You will need to remove it to get a view of the main relay. The removal procedure is the about the same as the Accord's procedure.

Locating the main relay using your ears and fingers:
Steps:

1. Turn the ignition to ON. You should hear two clicks (a thousand of a second apart) under the left or right side of the dash board. One click is for the ECU/Injectors the other is for the fuel pump. At this moment the check engine light should come on.
2. Listen carefully at the moment the clicks engage (usually somewhere underneath the dashboard.) Reach in and touch the main relay.
3. 2 seconds later you should feel a click if the main relay is at least working or wait until it works. At this moment the check engine light should go out.
4. Turn the ignition to start and you should feel a click, turn engine off you should feel another click.
5. Most main relays should have seven terminals. Please check if the location is already listed below.

How do I get the main relay out?
Steps: See four ways below so you can get it out. First you have to reach high up in there and do all this with one hand and a flashlight.
efiremoveinstall.gif A. Unbolt the bolt using a 10mm socket (picture A) or
Ab. Unclip the clip from the steel tab and slide it apart (picture A) or
B. Separate the steel tab from the plastic case (picture B) with a large flat screw driver jam and twist between the plastic case and the tab or
C. Disconnect the negative battery terminal. Unclip two clips I pointed with two arrows (picture C, or below) with a small flat head screw driver or with a strong thumb and then yank it out (D.) This is the preferred choice by many. Mechanics prefer choice A and maybe B. See detailed relay circuit photo.

Where is the main relay
located on the Accord?
Why doesn't my Honda or Acura start sometimes? The main relay is famous for stranding people for a few minutes usually in a parking lot in hot weather. The problem is so common that it's been coined the "petrol station fuel relay" from fuel station attendants. The technical name for the main relay is PGM-EFI Main Relay Assembly. PGM stands for programmed, EFI stands for Electronic Fuel Injection

Take out the main relay and check the solder joints.
Reheat the solder joints if you see any tiny cracks.
You can also buy rebuilt main relay from eBay.

If the main relay does not solve the problem, you will need to check the distributor. Open the distributor cap and the rotor and see inside and make sure there are no oils leaked from the bottom side of the distributor through oil seal. Replace the distributor with a rebuilt or new one. There are many distributors listed at eBay.

I think it's possible that the fuel regulator is stuck open and allowing the fuel to return to the gas tank. If your car is like mine (1991 Acura 1.8 engine), you can try this experiment: Pull the vacuum line off the fuel regulator (it's on the end of the fuel injector manifold and a hose connects to it to return gas back to the gas tank) and temporary plug the hose with a small bolt or golf tee. If the regulator is not stuck open it will make the fuel injector manifold at the highest pressure. Start the car and see if it dies or keeps running ok. If it runs ok then the vacuum control is not working right. If this doesn't help, try changing the fuel regulator valve or pull it out and test it with a vacuum off and on. When the vacuum pressure is present to the valve the valve is suppose to open slightly, this allows fuel to bypass the fuel rail and return to the tank.
