Maybe that's what the "hall effect" is meaning. I always called it a pickup coil. It's the gizmo that fires the booster coil at the appropriate time. Whenever we had trouble with our Dodge van, that's always what it was. Once it failed completely, once it just acted stupid. As a matter of fact, when it was stupid, it was heat, not cold, that made it act stupid. It would run fine when my dad drove it to work, then he would come home, park it, and the heat from the block would rise into the motor (and that sensor) and it would run like a junk car for my mom in the evening.

I know this has been a thread before, but was wondering what the turnkey options are for heated fuel systems for WVO. any links? are there any places in Seattle that do the conversions? I'm in class every other week until February 2008... no time for websurfing... :) john ----- - ---------------------------------------------------------------------- Snohomish, Washington -o|||||o- where Jeeps don't rust, they mold http://freegift.com ** http://wagoneers.com ** - ---------------------------------------------------------------------- ------------------------------ Date: Sat, 3 Mar 2007 18:47:59 -0800 (PST) From: john Subject: [db] value of a '91 rust free GW I've got someone interested in Omega, they've made an offer... but I'm trying to figure out what he's worth, if I should take the offer, wait for another buyer, put it on ebay or counter. Book value is right at $5k, but on ebay the '91's, even rusty ones, have been going for $6,800 to 11,000. Of course Wagonmasters gets $18 to 32k for lower mileage pristine versions. So, what's a totally rust free, 163,400 mile, factory sunroof equipped, 10.46 mpg, professionaly tinted windows 1991 Grand Wagoneer worth that needs a wee bit of body work and some decent tires? :) Of course there are other cosmetic issues with it... oh, and when I put my remote starter on it... it starts right up. connected main terminal on the starter and the solenoid on the starter... is there another relay in the system? Or is it the alarm system that has failed? BTW, Ed, the '86 300E has a number of cosmetic issues... nothing serious, also has 220,000 miles... sunroof cable needs to be replaced, doesn't close all the way, idler pulley is bad, otherwise looked ok. If I sell the Grand Wagoneer, I'll be looking at getting one of those automatic fuel systems for the Waste Veggie Oil... john ----- - ---------------------------------------------------------------------- Snohomish, Washington -o|||||o- where Jeeps don't rust, they mold http://freegift.com ** http://wagoneers.com ** - ---------------------------------------------------------------------- ------------------------------ End of diesel-benz-digest V1 #2405 **********************************
