The motor cranks fine but won't start. Actually, it cranks more smoothly if the coil wire is pulled off. It's almost like there is no spark or the spark is coming at the wrong time.
It may have had a loose battery connection for a while, because sometimes it would crank very slowly, especially if the lights were on. But all connections are fine now, and the battery is fully charged.
What would make it run fine and then suddenly not start at all?
I had the same problem with my truck and it was the distributor cap and rotor.I had to replace the spark plugs as well because all that cranking over fouled the plugs.
Better check that distributor cap for damage on the inside. It's simple. Just need a flat tip screwdriver. If thats fine. I'd check voltage to coil and if it was 12 or more I'd through a coil at it. It's an easy repair.
First you have to determine weather you
have a FUEL problem or (ELECTRICAL)Spark problem ??
Pull the coil wire off or a easy to get
to spark plug wire, Lay it close to were you pulled it off of (Do not
hold or touch you may get SHOCKED) and crank motor (need two people)
look and listen for a spark, if you see or here a spark, then go to
next step which will be to check for Fuel (gas). Be very careful when
checking fuel, as most lines are under pressure and may cause bodily
harm such as BURNS to EYES and SKIN!! Loosen or pull the inlet fuel
line off and put rag over line. Some fuel injected vehicles have a
fuel rail the has a valve that looks like a tire valve. Put a rag
over this valve and push it in with a small screw driver and have
someone crank motor a couple of times to see if fuel is coming out.
If NO Spark---Could be a lot of things
Points (older vehicles) Modules, Coils, Crank Sensors, ECT......
If NO Fuel---- Could be Clogged fuel
filter, Fuel Pump, Fuel pump Relay, Fuse, ECT..........
Hope this helps you ??
