EF Main Relay?

Now that the outside temperature has warmed up, I seem to be having an intermittent starting problem with my '88 hatch. The problem arises both when the car is cold and when it's at operating temperature. I crank the ignition and the motor turns over, however it does not start ... wait a few minutes to try again and it works (sometimes on the first try, sometimes I have to try multiple times).

Having done a search, I didn't come up with a whole lot of information but these symptoms seem to sound like a main relay problem. Is there anyway of testing my main relay out to see if it is the problem? Does anyone have a picture of where the relay would be located on an '88 hatch (I've tried looking in the driver side kick panel area with no success)? Can anyone that's purchased a main relay recently, tell me what they paid from the dealership?

Any help is appreciated ... thanks.

I bought my EG main relay last year from honda, and it cost me $40 or something.

I experienced the same problems as you're having now, last year once it got hot during the summer. I don't know how to test your main relay, but what you're experiencing sounds to be the tell tale sign of needing a new relay. You can tell that your motor won't turn over, because your fuel pump won't prime (you won't hear the sound that you normally could).

it's really easy to fix it. pull the relay out, it's behind the fuse panel up on the side.... then take the case apart and look for what is known as dry solder joints.... basically where the solder has broken off in a circular patern around the board. resolder those dry joints and you're set. I did this to mine last year sometime and it's given me no more problems. also did this to my dad's VW when it's main relay went out, and he's had no more problems for two years. I have pics somewhere of the dry solder joints, lemme see if I can find them.
