1997 7.3 Won't Start Cranks Great

Um, it's kind of embarrassing.... I didn't do it, my roommate was looking at it for me and said he checked fuse #22. I asked him to double check it and I went out and watched him check it. He read the fuse chart wrong, and was checking the wrong fuse. Fuse 22 was out . We put a new fuse in and it started right up. It starts a little hard but has always started a little hard since I got it.

Ok, so after we got it running, it ran about a day, and now it won't start again, it keeps blowing the #22 fuse, any ideas why? We replaced the "PCM" (I think its what it is called). I blew two #22 fuses this morning trying to start it (I tried to switch the relay for horn and IDM like was suggested in a previous message).... .

For the applications that apply, each need to be tested for current draw that is excessive.
Since the combination of those that do apply for the sum total, one is faulty and takeing the currernt to the fuse limit and causing the fuse to fail.
Any fuse passing current at it design limit will fail over time.
Throwing parts at it is a guessing game to get lucky and is costly.
Better to do testing and find the fault.
Sorry it's not simpler.
Good luck.

Well, you need to know where the parts are.
You need some information to reference for testing them.
You need a volt meter with current and resistance ranges to measue with.
At this point your out of luck without the means to do the testing.
The problem is simple but finding it takes all the work.
Good luck.

solder joints come loose, fix them if you are feeling spry, just unplug it if not.
