If you have this problem, this is what I did, and what solved the problem
Replaced main relay----------NOTHING
Replaced ignition switch------NOTHING
Replaced the ECU------------PROBLEM SOLVED
I would atleast always start with the main relay
and the rest of the thread is a bit pointless, but read on if you like

My car is having problems maintaining a continuity to the main relay circuit. This began last week on sunday.
my main symptom is while the key is in the ignition and in the accessories position, the CEL is flickering, and you can hear the main relay clicking with each flicker. This problem seems to come and go.
Since sunday night of last week, I have replaced the main relay, (new), and the ignition switch, (also new). replacing the main relay, (at first) had no effect, but two days later I had no symptoms in driving the car back to my apartment, (10 miles at night), where I decided to replace the ignition switch, thinking that it might have gone bad. Afterwards, I went 120 miles, (over a period of 10 days), without seeing a symptom.
But today, (10 days after last sunday), the CEL flickered again, and is not staying on long enough to prime the car. Though it did breifly fire up, then died as the CEL flickered again, and now continues to flicker.
My starter does not seem to have any problem at all, I can crank the starter all day if I wanted to, and my battery, (optima yellowtop), and alternator are both only 6 months old. 6 months ago my alternator went bad, (it was puting out upward of 300% of normal voltage), since it was still only puting out the normal amount of amperage, it fried several things, including my then 2 year old yellowtop battery, gauge cluster, radio, every single lightbulb, and my tcu and ecu. I replaced all of those things, most of the major components from junkyard aquisitions. Also my grounds are pretty well connected. Three months ago, I replaced my heater core, and was able to see that all of my wires under the dash look to be in decent condition, and I am 95% certain all wire connectors are firmly connected.
My current TCU/ECU are from the junkyard, I am wondering if any of those could be the culprit.
I tried to be as detailed as I thought might be helpful.
I appreciate the time anyone takes to read any of this, and thank everyone in advance for their replys.
