The engine will not run with out a working EFI main relay...
Are you sure that the relay that you got is good?
Have you tried putting the jumper wire back in as it was and it still wont start?

If it'll start with the jumper and your positive that the new relay that you have is good, then its a wiring issue to the coil side of the relay.

If its not stating at all even with the jumper, then chances are its the code 14. This is going to be either the ignitor or the IGf signal wire from the ignitor to the ECU (or a very slip possibility that its in the ecu but this is pretty unlikely).

The code 14 (no igf signal) is a shut down code (for lack of better terms). If the ECU does not get the igf signal repeaditly, its shut down the injector triggers and the IGt signal thus shutting the enigine down. This is simple to prevent flooding of the engine. The IGf signal is simply a return signal telling the ECU that the ignition event for the last sent IGt signal has occured. In short, IGt signal tells the ignitor to fire the coil and IGf tells the ECU that it did.
