7mge swapped 4runner help

[laturnus]

i have a 1987 4runner with a 7mge swap out of a 89 supra. I have had several problems with the wiring in the truck because i obtained it from a close friend who in turn bought it from someone else who had no idea how to do automotive wiring. I finally got it running today with the E1 and T terminals jumped to do the timing. It was running perfect at 15*. I turned the truck off with the diagnostic jumper wire still in, when i tried to start the truck again it would not run. I pulled the diagnostic wire out and it started to run very rough like it wasn't timed again. While it was running poorly, i jumped the terminals, it revved very high then died suddenly. It starts with no jumper in and runs for about 5-10 seconds at what sounds like 400 rpm, but with the diagnostic jumper in it will not run. Someone please help.

thanks,
Mark
