? ? This evening, after a long evening of driving all over town, we stopped for the last time before going home at a small convenience store a few blocks from home.? No sign that anything was amiss up to this point.? I try to start the engine, and it doesn't fire.? It turns over just fine, but doesn't start.? I walked home to get my OBD-II system and a few other tools, and walked back.
? ? The OBD-II system can't establish a connection.
? ? When I turn the key to the ON position, I do not hear the usual fuel pump sound from the back.
? ? On checking fuses, I find that the #4 fuse (â??â?¢? Daytime Running Lights (Canada)â?; â??â?¢? Ignitionâ?) (This is not a Canadian car, and does not have DRLs) is blown.? I replace it, and try again to start the motor.? Still no start.? I check, and find that the new #4 fuse has also blown.? I put a 30-amp fuse in (instead of the proper 20-amp) and then turn the key to ON but do not hit the starter. I immediately turn the key off again, and go out and check the fuse.? Sure enough, it's blown again.
? ? So, apparently I have a short circuit somewhere in the system.? I don't need to try to start the engine in order to blow the relevant fuse; I just need to turn the key ON.
? ? Any ideas where to look?
? ? Oh, one other thing? â??? I've noticed now that when I turn the key to ON, the CEL does not light up.? Shouldn't it light up whenever the key is ON and the engine not actually running?? Would a failure in the same circuit (Ignition?) that uses fuse #4 prevent the CEL from lighting and also prevent an OBD-II system from connecting?? Would this same circuit keep the fuel pump from running?
? ? I've checked most of the other fuses in the underhood box, and found none others blown.
? ? BTW, how do you get fuses 1, 2, and 3 out?? The manual says, â??Have these fuses replaced by a qualified technicianâ?, and they appear to be locked in in some manner so that simply pulling on them won't get them out.
