This is beyond frustrating.

Car starts and runs no problem. Checked timing, car sounded and ran like a dream.
Wednesday 5-5-10
Car starts and runs as I check ignition timing. Go to start again, and while it was running there was a clicking noise coming from the ECU area. When some thing near the ecu started clicking the idle surged a little bit and would click as the engine would drop in rpms. The engine shut off and when going to start the car back up, it cranks but does not start.
The car was running for a good ten minutes to warm the car up and I shut it off for a little bit to retorque the head studs down. As I started the car again this is when the problems started, as stated in the above paragraph. No changes were made to the car between the starts.
I pulled the ECU and checked it for smells, leaks, and anything that looks wrong. I dont see anything. None of the caps apperead to be leaking and I checked to make sure the chip was not loose. Nothing appeared out of the ordinary inside.
ECMLink did the ECU. So i trust the work.
When the ignition is turned on, but the engine not running DSM Link will not connect to the laptop. The usb ports were verified in the computer and nothing has changed. The message that DSM link pops up with is the I/O Failed: Connection timed out.
Weird thing is, 4 weeks ago I drove the car and all was well. Absolutely ZERO problems.
I borrowed 2 socketed EPROMS from a friend today. I swapped ECUs with one in stock format. Cranked the car over and it chugged and popped like it was going to run. All 3 ECUs gave me the same result even with the DSMLink setup swapped over.
I am still being kicked off Link (IO FAILED: COMMAND TIMED OUT). I spoke with a very reputable member and he said it sounds like a relay is causing this issue.
I checked my MFI relay box that sits near the ECU and that seems to be fine.
I pulled the harness and am checking for broken wires and what not. My buddy and I are working on the harness and notice that my wires leading to the 3 ECU plugs are all tangled and arent neat whatsoever. We were comparing it to my extra 1g harness I have. Could this be part of the problem or should this throw up a red flag?
Help is greatly appreciated. All of this was COPY AND PASTED from the DSMLINK FORUMS. I have received NO help there and this is urgent to me.
