Ill be sure and check it when I get off work...
I got your message REDZ as I was on my way out the door to come in to work... I was out hardcore! As I said before, "Im getting everything as far as lights and sounds go."
Now, this may sound dumb, but... What is a MPI relay Dweet?
AS far as checkin voltage and that stuff goes... I dont have the equipment or the "tech know-how" to do that kind of stuff... oops.gif

Ill look at it again...
Now that I think of it, and I cant remember what they are for, but how do you tell if the solid black ones are good or bad?

No, Ive got three fuses in there that are completely black. No windows or anything that I could see...
I do have the ones that are colored and have the window in the top, those are all good... Ive got the little clear ones that are all good as well.

I was trying to test the fuses (relays) at one point. I thought the Radiator fan was out, so I plugged it into the Horn (they're the same size, I would only swap them out with same sized relays). The horn worked, so I knew my radiator relay was fine.
See if you can swap out the ECU relay with another one of the same size and test it. Try starting your car and testing whatever you put the old ECU relay into. Swap them back after the experiment.

MPI Relay = Multiport Injection Relay. It basically tells your ignition to start working because other prequesites are met to allow proper spark. Ahh its called the MFI Control Relay now in the new hyundai's, its the MPI in the old ones. Im looking at webtech as Im typing this now.
It is located here...

Btw.. sorry Redz for the double post I was doing liek 50 things at once at that time because I was working on the elantra and posting on here and on anothetr site etc...
