OK thank you! I messed around with it today and got it to start: it acted all haywire at first, and the tach went way up to like 5K (!!!, although I am suspicious if it was actually revving that high). I then killed it, went to my job, and tried again tonite. This time it started fine, so I decided to jiggle the Hall connector while it was still running and BINGO: the car began to hesitate, or revv and get huffy, as the symptoms have been since this started over a week ago. The tach responded to cranking on these times of starting, but I can't remember if they did when it was no start/no spark (pretty sure it was NO).

You're saying it's easy to pull it, but according to the FAQ etc it at least sounds like a real nitty gritty gearhead's job to swap out that Hall sensor at least once the unit is out. I will look for a complete unit at the yards tomorrow. Do you, or anyone else who is reading this, happen to know which of the 740s use the same distributor with that sensor in it? Should I just look for any that match the external description (i.e. a three prong Bosch connector)?

Thank you! Stoked this is getting somewhere! Viva brickboard!
