Toyota Repair: EFI Fuse, toyota solara, crank sensor

Question
Over the past couple of weeks, I have been troubleshootung my 2000 Toyota Solara 2.2 5-speed. The frist instance, it wouldnt start but it would try to turn over. I replaced the 100a alternator fuse and crank sensor. It still wouldnt crank so we found the EFI fuse was blown. I replaced the 15a fuse and my car ran for a couple days and now its dead again. I am constantly blowing that same fuse, EFI fuse. If you could possibly help I would greatly appreciate it

Answer
An electrical problem like this is very hard to diagnose without having the car to work on. There are a lot of electrical circuits on this fuse, mostly engine control related, do a visual inspection of the wiring under the hood to see if it turns up anything, rodents like to chew on wires so that's one possibility. Look for any damage to the insulation of the wires.
