Just replacing the EFI relay shouldn't have eraced the code.. Unless you pulled the EFI fuse at some point during it all... To erace any codes, the BATT signal to the ECU has to be pulled and this comes directly from the 15A EFI fuse.....

So now with the jumper it still dont start... Hmmmm...

Does the ECU give you a "NORMAL" code (steady flashing) now if you try to pull codes?

As for the testing the ignitor, there should be a test proceedure in the BGB. If you cant find anything, I can tell you a way to do it. Its not really that hard to do on standard toyota ignitors. It just requiers a couple of lengths of wires, a standard 12v test light, a 12v powersupply (car batt) and a 3v supply (2 AA battery's do the trick).
