Ok here it goes. Yesterday i turned on my Rex before i went out for a drive. It was warmed up already so it was idling at around the 750-1000 RPM range when suddenly it died. "No Biggie" i thought since it has happened to me once or twice. I turned it right on and it was fine until today. I Turned it on to go to school and it ran fine. After leaving school i turned it on and it died suddenly. 'WTF?" I told myself. With the key already in the ignition i turned it to the ON position without cranking the motor. I didnt hear my fuel pump. Then i completely TOOK OUT the key and then put it back in and then i heard the FUEL PUMP. It works like that sometimes and sometimes it doesn't. What can my problem be?

I don't understand how sometimes i hear the fuel pump and sometimes i don't. But after i turn it on it stays on. So i dont get it...

Please help honda-tech!!

 

Sounds like your main relay.
Turn your key to the on position and you should here a click and the fuel pump whining.

I had the same problem. I would be driving and my car would just shut off and I would roll to a stop and try over and over to start my car. So I searched around the web and found that the main relay could cause this.

Changed mine out and hasn't happened since...

 

Where is the relay located??

 

It's by the underdash fuse box to the left. It's a kinda hard to see. Unbolt it once you find it and and unplug it. There is a way to test it...you'll have to search.
I just went to my local junkyard and bought one. $5 dollars or so.

 

I just talked to my buddies Uncle who owns a smog shop and he also said that its the Fuel Relay. Can i test it with a volt meter?

 

The main relay controls the fuel pump.

 

You think Kragens or Autozone will have one?
