93 Ls400 Not Starting

[93whitels]

Hello everyone, this is my first post. My car seems to have trouble starting. It sounds like it wont turn over and run when you turn the key. Recently i replaced the engine wire that connects the cam and crank sensors as well as a few other things to the ecm i believe with a harness that had crimped connections. The car started and ran well for about a month. Then one day the check engine light came on and eventually had to limp home. I got a tps sensor code as well as a rear driver abs code because my trac and trac off light was on as well. Additionally I had a coolant level low warning light. I went to the junkyard and replaced the engine wire because the other one wasnt in good condition and this seemed to fix it last time. Also replaced the tps and coolant level sensor. Still no luck. I had an extra ecu that i swapped, still no start. If i turn the key to only the on position the throttle trac motor makes a clicking noise for about ten seconds, then turns off. I was thinking of replacing it but couldnt find it at the junkyard. Sorry for such a long post. Any help would be greatly appreciated. Thanks.
