Help!! No spark.........
Hey everyone,
This evening I go out to go somewhere in the Ford and bang won't start. It cranks and cranks and nothing. I took off the air cleaner and poured a small portion of gas down the carb. I cranked and nothing....WTF? The truck is my 84 F150 300 6. New plugs,wires,cap and rotor button. Could it be the coil? Do these go out very often? Can I test it? Where should I look? I have power in the cab and battery is fine. At first I thought it may have flooded but all I did was jump in and crank as I always do. Only this time nothing.........please help.

Pull one of the spark plug wires off a plug; insert a screwdriver fully into the boot; hold the
wire & screwdriver near a ground as somebody tries to start the engine; if there is spark,
you'll see it.
Got that screwdriver idea from Diesel_Brad; the way I had learned to do it as a kid was to
merely hold the boot near a ground, maybe pull the boot up the wire some so the conductor
is closer to the exposed elements but that requires wires & boots that move like that.
All this does is verify if you have spark or not; figuring out WHY there isn't any spark is a
different problem....

Just walked outside and it started. It sputtered but it finally started. I'm still leaning toward flooded. I swear I think it's a reincarnated Christine. Mind of its own.....

If you try to do this test ... especially on an MGB ... with a WET fender (!!!) ...
DO NOT LEAN ON THE CAR!!!!!
Use a rubber fender cover ... something that will NOT conduct electrickery!
You'll do more than just shock the **** outta yerself!
Ask me how I know!

Ok, It wouldn't start again. So I stuck a screwdriver in the number one spark plug boot and had my wife crank it. No spark. So I jiggled some wires and bang it knocked the **** out of me. Turns out the little ground wire on the neg. battery terminal had came off. Now starts fine. Thanks for the help guys.
