I would do some more checking before buying a coil. Coils rarely fail. -----Original Message----- From: Vanagon Mailing List [mailto:vanagon@gerry.vanagon.com] On Behalf Of Raymond Paquette Sent: Thursday, February 25, 2010 7:44 AM To: vanagon@GERRY.VANAGON.COM Subject: Re: testing Hall sender 1987 Syncro, 2.1 Okay, what I get with this test is: no spark no sound from injectors (that I can hear-is it reasonably loud?) fuel pump cycles on and off at consistent points in the engine revolution suggestions? My coil is not to the specs in Bentley: 2 ohms primary, Bentley says it should be (0.5-0.8) 3000 ohms secondary, which is in the Bentley range I'd just run out and get a new coil, except that I already got a new coil, and it matches the specs on my old coil. But it was "Wells" brand from Autozone (yes I'm an idiot, no need to tell me). I figure that it's fairly likely that I got the wrong coil or a bad one. I guess that I need a coil, but am concerned that I didn't hear the injectors firing when I did Ken's test. Is the coil somehow involved?
