Main Relay info

[Oldblueaccord]

There seems to be some misinformation on the main relay and its function I wanted to try and clear up.

First off I have a 1988 Lx-i with about 260k ( by tomorrow). J code car.

I started the car with the relay hooked up. Runs.

I unhooked the relay and start the car again. Car cranks over will not start.

I hooked the relay up started the car. Runs.

While it was running I unhooked the relay. Car stalls.

Understand that a bad main relay means you have no fuel, but the car will crank over but not run.

12-64 Helms service manual step 9. Connect a jumper wire between the Blk/Yel #5 and the Yel #7 the pump should work with the ignition switch on.

This is a good test to see if the relay is faulty or not. Also to get you home in a jam if you car wont start.

Remember the relay is there for safety purposes so that in the event your in an accident the pump does not keep running and cause or keep fueling a fire.
