ok, car sat for several months and now won't start. the engine cranks but won't catch so we have been replacing parts and hoping it starts working. We have replace the plugs, wires, distributer cap and the coil, still nothing. Weird thing is that it hasn't started, just a bunch of cranking, and the #3 plug, which is new, is black with soot while the other 3 still look new. about to get a fuel and compression tester, any other suggestions as to what we need to check next? oh, and we did put in some fresh fuel just in case. Any suggestions appreciated, thanks (not sure if it matters but it is a 92 capri with a 93 engine as we cracked the block early on after the water pump/alternator belt broke)
