remove the pcm relay.as you are looking at the fuse box it is the top right side.have replaced tons of these for the exact same symptom.some times a visual inspection will tell you it's bad/the terminals will be green or corroded.other times you cannot see anything wrong with it but it has an internal fault.good luck.

We have had a problem during the hot months when we run the air-we had to change the ignition fuse. the computer would run hot-we really don't know what the problem is, but during the cooler months no problem but when we run the air in the summer months it will blow the fuse. Don't really understand what the connection is. Put it in the shop to no avail!! Nobody will listen to my husband about what the problem is. He said he had a truck to do the same. We would get it to crank after changing the ignition fuse.

I had the same problem but I fixed the so called non serviceable relay. If you need me to do this to yours send me an email. Eclipsepro2000@yahoo.com
