A couple of weeks ago, my brother was driving his 2001 Ram 1500 van with a 318. It started blowing fuses on the ignition spark circuit. He replaced the fuse several times to get it home. Now it will not run at all. What will cause this? It's getting fuel. Can we bypass the fuse to the coil and make it run? He has replaced the computer, and the crank sensor. It is no longer blowing fuses, but has no spark.
