took the valve cover off to polish it and do a little cleaning, but when i got the cover back on the car wouldn't start. crap. replaced the distributer cap, rotor, plugs, and wires, since the old ones were really wore out. still won't start. crap. took the coil out and took it to the parts store. they tested it and they couldn't get it to spark. interesting. it worked fine an hour before when i pulled the car into my shop. weird stuff. anyone else have anything like that happen? that's a first for me! so now i got to come up with $89 for a coil. the muffler fell off too, it was so rusty. oh well. quick run to the parts store for a new coil, then got the new coil on and it started right up.
