T-Harps Posted November 11, 2015 Report Share Posted November 11, 2015 For the last month I have been having trouble starting the Starion. At first I could wiggle the knock box connector and it would sometimes start, and then run perfectly. It would also still start while the engine was warm (for about an hour after shutting off). Now it doesn't start at all, and the cause is no spark. I replaced the pickup coil today but still no spark. I also checked some stuff I red about the knock box connector on the forums here: With Key On:- Red Wire gets +12V- Blue/White wire gets +12V With Key Off:- No resistance between white wire and left side of pick up coil- No resistance between black wire and right side of pick up coil- Other black wire goes to ground What else can I check? Any Suggestions? Link to comment Share on other sites More sharing options...
BillS Posted November 11, 2015 Report Share Posted November 11, 2015 Still could be the pick up coil. I had a bad one out of the box. Link to comment Share on other sites More sharing options...

ucw458 Posted November 11, 2015 Report Share Posted November 11, 2015 The 83-87 plastic knock boxes are known to fail the way you describe. The 88-89 metal boxes are more robust. But the connectors are different so it's not plug and play. I would try another knock box. Link to comment Share on other sites More sharing options...
T-Harps Posted November 12, 2015 Author Report Share Posted November 12, 2015 Its an 85. Is there any test for a bad knock box? Link to comment Share on other sites More sharing options...
ucw458 Posted November 12, 2015 Report Share Posted November 12, 2015 Yes, power in, dizzy signal in, good ground, no signal to coil = bad knock box. They can fail intermittently. Meaning fail when hot then work again for a bit after cooling off. Link to comment Share on other sites More sharing options...

ucw458 Posted November 12, 2015 Report Share Posted November 12, 2015 If you get it going it's a good idea to keep a spare plastic knock box with screwdriver in the glove box. I did and it saved me from having to tow my SQ. Sitting at a light one day and the engine just shut off. Knock box was dead. Tossed in my spare and went home.
