JB_BA Posted June 16, 2003 Share Posted June 16, 2003 Well, now I have no spark from the distributor to the plugs...!!!WHAAA! I replaced the ignition module in the distributor to no avail...and I'm about to check to make sure the distrib. is getting power, if it is, does that just mean it's time to replace the distributor, or should I check anything else before I spend $125? Thanks, JB Quote Link to comment Share on other sites More sharing options...
dmyntti Posted June 16, 2003 Share Posted June 16, 2003 What type of distributor. It could be the coil, the coil wire, the rotor, etc. Quote Link to comment Share on other sites More sharing options...
JB_BA Posted June 18, 2003 Author Share Posted June 18, 2003 I'm pretty sure if there is an ignition module in the distributor there isn't a coil...right??? Arg...looks like this one is going to Custom Performance... JB Quote Link to comment Share on other sites More sharing options...
dmyntti Posted June 18, 2003 Share Posted June 18, 2003 I am talking about the ignition coil. If you have a module inside the distributor then you don't have points. I assume that since you are talking about a module inside the distributor and your on the Chevy V8 forum then you probably have an HEI. The coil on most HEI distributors is inside the cap. It has a button with a spring on it that connects it to the rotor. Quote Link to comment Share on other sites More sharing options...
JB_BA Posted June 19, 2003 Author Share Posted June 19, 2003 Oh ok, I see what you're saying. So I could test the wire with a light, but how would I check to see if the coil was bad? Will there be a black residue where it malfunction? Or should I look for something else? The "button" is what throws the spark right?

dmyntti Posted June 19, 2003 Share Posted June 19, 2003 The button connects the coil output to the rotor which directs the spark to the correct wires. It is hard to check the secondary side of the coil but you can see if the primary (low voltage side) is working. Put a test light on the tach terminal of the distributor. Then crank the car, if the light blinks then the primary side of the coil is switching. If it is then I would pick up another coil and try that. Another common problem with HEI's is the wire that goes to the module from the pickup sometimes shorts to the housing this usually shows up as an intermittant miss though. Hope this helps.
