Main Relay... do a search you'll find plenty on it.

Fix it, dont replace it.

i dont get that comment my intention were to buy a new one...if thats what you were trying to get at....anyone know why it does this only when its hot?

 

he is saying that if you seach, there are write ups on how to fix it yourself, rather than paying the money for a new one

 

You can re-solder them. But for the 40$ they are worth, I bought a new one, well, new to me (used, but was the new style so it didn't fail). The originals fail after 10-15 years. The solder breaks loose and doesn't connect 100% of the time. Usually when it's nice and hot and the plastic expands a bit.

 

My main relay was a chronic problem out here. Cheapest replacement in town was a 2 day wait and $59. So I did a search, spent 5 min resoldering and its been solid for the last 18 months.

are the main relays the same from 88-91

 

actually i dont think so, i went to a autoparts website and they have different part numbers listed for them

 

anybody else know if there all interchangeable between years and models?

so when car wouldn't start and the main relay was bad you didn't get spark whatso ever as well?

 

What you problem is, is that the fuel pump isn't working.
It has nothing to do with spark.

 

But I don't mean your fuel pump is bad, just that the main relay is what turns it on.

 

I grabbed 3 from a junk yard a month or so ago. one from a 89, one from a 90-91 and one from a 89 teg. They all worked on my car even though the teg one had a different part number and was a different color.

Anyways its easy. Open the relay up, touch each solder point with a solder gun until it pools then remove the gun. Repeat on each solder point.

 

anybody have any other suggestions on what it could be?

 

It certainly sounds like the main realy. Its a 30 minute job to test this out. I suggest you re-solder the replacement used relay that you're planning on using, to be absolutely sure that when you change the relay, you're putting in something that will work all the time, and not just when its cool. When you said you tested the replacement relay, did you heat it up with a heat gun to try and simulate the conditions that it will see when you're using it in the car?

 

when it gets hot..the pads stick to the bottom and dont lift up when you turn the key..same **** happened to my 89 Si
