No spark condition.

Greetings all. I'm new here, and I've run into the apparently frequent problem of no spark in my Concorde. It's a 1996, 3.3l v6 with 143K miles on it. We've changed the PCM, coil pack, ASD relay, cam and crank position sensors, to no avail. The timing belt is not broken, and appears to be fine. My son was driving it, said it "surged" on him a couple of times, died once, then started fine. He parked it, tried to start it, and no go. I got it to start and moved it to the front of my driveway, parked it, shut it off, and nothing after. The weird thing was, that the fuel gauge quit working as well! The tach and speedo jump when cranking the engine, but no start. It's probably been asked before a million times, but any ideas/things to check/look for? I'm about at my wits end. Thanks.
