I thought I had this problem fixed yesterday, to bring you up to date after my 4runner would sit overnight the battery would be dead, I recharged the battery, pulled the neg. cable and ran my test light between it and the neg post will the key off doors shut etc and the light lit up. I started pulling fuses, when I wiggled the EFI relay the light would blink then go off. I pulled it and squeezed the terminals so it they would fit tight put the relay back in, tested it and had no draw. I get up this morning and you guessed it the battery is drained and my test light says its the efi relay again but it seems to be making good connection. I have already tried another one and it does the same thing. I am thinking this also has something to do with the engine miss I have also. How can this relay be causing a draw?What tells the relay to open and close the contacts inside?

 

A test light is not the correct way to test for a draw!
If you do not have a multimeter, buy a cheap one from Sears or Radio Shack that can measure mA = milliamps. Then you will able to properly fix your vehicle.
I'm not saying the relay or computer aren't bad, but helping you find out what is.

You're going to have draw at the battery. The truck clock, radio - both take current. The ECU may or may not take current in the OFF position.
Get an ampmeter.. Otherwise you can't solve your problems.
