Posted November 3, 200816 yr comment_265277 --------------------------------------------------------------------------------guys looking a a 78 for this girl, unknownn how long since it has run, said it started with fuel leaks and just let it sit for a long time.Anyway this has got me a bit puzzled, when you turn the key on and crank engine wont start, very weak spark but when you let off the cranking the ign continues to fire non stop until you turn key all the way to the off position, you can even here it inside the cap buzzing!!! If you pull the cap and watch it has a strong continuos spark between coil wire tip (center electrode and one of the plug electrodes, any clues here??

November 3, 200816 yr comment_265278 What I'd do is take a known working ignition switch (the electrical part) with me, unplug the connector from the one in the car, plug it into my switch, turn it with a screwdriver and see if that condition still exists. If not, the switch would be the cause. Link to comment https://www.classiczcars.com/forums/topic/29856-ignition-gurus/#findComment-265278 Share on other sites More sharing options...
November 4, 200816 yr Author comment_265393 pretty sure its not the ign switch, now thinking possible shorted pickup in dizzy, isnt that the only thing that triggers spark???

November 4, 200816 yr comment_265396 The reason I mentioned the switch is because everything begins with it especially on the EFI cars. If it malfunctions to the point where there is cross tracking inside the switch all kinds of wierd things can occur.
