2G No spark after sitting

[LidnDom]

After battling to get my car started after installing FIC 1120s, I finally got it start up without any trouble. The only issue was idle surge and I figured it was my injector seals. After waiting a week for new seals my car wouldn't start after installing them. I began the initial diagnosis of a no-start and found that I was not getting any spark.

I tested the ignition coil and received negative results. I also tried swapping out the power transistor and charged the battery. Assuming that the ignition coil was bad I exchanged it for a coil-on-plug system which I had laying aside. The car still does not start and I am completely stumped. How could I lose spark from just sitting for a week?

I fixed the issue and the car now has spark. I'm not exactly sure what changed it, I just put the ignition coil back in and took out the MPI fuse and put it back in. ECU problem?

could have been corrosion on one of the connectors. or on the fuse end terminal.

On of the connectors could have been loose not getting the full current. Ive had a fuse half way in before and had intermittent results. Could have been a cause.
