Truck has not been driven much but started often. Started one day and ran/idled fine for about 15 minutes, then, just stopped. Now it won't start at all. What is the problem??? Checked the coil and it is not firing, just turns over. Any help on replacing coil would also be much appreciated. Also. while trying to figure this out, the EEC-IV Power distribution fuse kept blowing. ??? Please help.
