i think i blew my ecu when i was messing around with it today.
the engine turns over but will not start. is this a blown ecu or what. dont want to buy a ecu when its something like a relay or fuse.

HELP!!!!

make sure those two wires that branch off the main harness next to the ECU are still connected to their clips. I had the same problem after doing the first swap, that one connector with the 4-6 wire connector is what you need to be clipped in.

Turn your key to "on", and see if you have a light on the ECU, and if it will report error codes. If it does, then nevermind my suggestion isn't it. If you don't get a light on the ECU or error codes, check out that wire harness clip.

Check the relay... it is the little green thing near the ecu. Try swapping it with the AC or fog lights relay found under the hood.
