Now, if you're keeping it until it gets parted out, it might not be an issue. Generally, I avoid ABS on most things whenever possible. On an XJ, you do this as ABS delete vehicles got the better rear axle, and it's far easier to stick the stronger ABS front shafts in a rig than undo all the ABS junk to put in a better rear end.

No light show. Sure sounds like an electrical grounding problem to me. *** That could be part of it. Per the shop manual, the O2 sensors all need separate ground returns. At the actual harness, ground returns have been connected together in strange ways, with barrel connectors in the harness. But I don't think this has anything to do with the no-start because engines have to be able to start without O2 sensors at all. > > If it were > "my" car, I'd look for the longest pier/warf that I could > find and just drive > it off. I "hate" GM crap! Sorry I can't be > more supportive... :( *** S'OK. This is, after all, a Benz forum :). It's been a very useful car - actually it's a cargo van. I got 75 thousand miles out of it with nothing but routine maintenance. I've carried everything from Mercedes parts to 4x8 sheets of building materials.

The plot sickens, as my mom used to say... I tested the MAP sensor with the Mityvac. It works fine. 20 inches of mercury, 5PSI. Moving on... While testing the MAP sensor, I stuck a vacuum gauge in the hole, and cranked. ***** THERE IS NO MANIFOLD VACUUM. NONE. ZILCH. **** Suspecting a bad EGR valve, I pulled it off, made up a blanking plate of soft aluminum sheet, and put it back on. Still no cranking vacuum whatsoever. I'm going to look through the book and see what other holes and valves are stuck in the manifold. Failing that, I guess I need to do a compression check. I hate to do that, because the sparkplugs on this thing are SO hard to get at. One of the hazards of having a van. I already felt underneath for loose sparkplugs, they're all tight.... Whatever electronic magic they've got going on, it's still a 4.3 liter engine being cranked at 150RPM - it's just GOT to be pulling air out of that manifold! - Jerry ------------------------------ Date: Sat, 16 Jan 2010 14:08:35 -0800 (PST) From: diesel john Subject: [db] VW Diesel pickup just got home with a 1981 Diesel VW Pickup, 5 speed, with a/c! no rust... solid engine, lots up recent service, new head/gasket, glowplugs, timing belt and so on... needs cv joints bad... front tires needed, no muffler, needs the stereo hooked up, mirrors fixed... paint is pretty bad, windshield cracked... but it made the 45 mile trip home on I-5... http://wagoneers.com/tmp/vw/ALL.html heading out to pick up 2 wks worth of WVO from Juanita, then back home to get about a months worth and head up SR9 to drop it off and pickup some BioDiesel... The last VW Pickup I had was an '80, didn't have a/c and only had a 4spd. this one has a lot of potential... Hey Jon, I need some VW parts ASAP... sun visor, headliner... :) what's the best place to get the cv half shafts? also first gear linkage needs to be replaced... a little challenging to find first, the rest of the gears are fine. not sure how big the tank is on this thing, has 400 miles on the trip odometer and the gauge is still between 1/2 and 1/4. The driver's seat provides excellent lumbar support, no problems whatsoever! Nice visibility from the driver's seat... john ----- - ------------------------------------------------------------------------ Snohomish, Washington -o|||||o- where Jeeps don't rust, they mold http://AMSOIL.com/redirect.cgi?zo=283461 si vis pacem, para bellum http://johnmeister.com http://wagoneers.com http://fotomeister.us - ------------------------------------------------------------------------ ------------------------------ End of diesel-benz-digest V1 #3226 **********************************
