Idiot or adventurouse? clogged injectors or dead IP?
I was on my way to Tahoe from Berkeley with what I thought was a fairly clean vormax R90T Filter system. Half way there, the car started acting like it was being starved of fuel. Gauge on filter was in the red.
FYI I've been running diesel for the last few tanks So I thought that because it was just diesel I could bypass the vormax and just use one of those little plastic filters that I bought at an auto parts store. Yep that was the only filter. Idiot time but I was stranded. Well it worked, and ran well all the way to Tahoe. Yes I had the gall to keep going on my path... Thought I get some more filters in Tahoe being I was half way. Two cold mornings later I tried to start it and nothing but cranking and rubber smelling whitish smoke. It was about 60 degrees out side by this time. I tried hooking up a can of diesel purge to the IP direct and I still couldn't get it started. It seems to almost start but never quite gets there. I cracked a line at an injector an fuel came out when I cranked. So I'm back in the Berkeley away from Birtha. Do I go back to Tahoe with a set of new injectors and filters. How bad was my idea to run a generic filter from auto barn? Is anyone else learning from this? Any other thoughts? as always thanks and let me know if you need to know anything else.

You say you're burning D2, now; assume that means you were using svo/wvo previously?
Take some new filters and a battery. Swap return and feed lines and see if it starts up and runs. If so the tank screen is probably clogged.

I Think if that was the problem it would have started on the can of diesel. Wouldn't it of? I will try that when I go back up in the morning. Any other ideas.
Thanks

I would have thought the small filter you installed would have closed off as well if there had been a lot of junk coming from the tank. Is it possible you just have a glow plug problem?
Just a coincidental failure but the episode on the trip a couple of days earlier might have fixated you too much. If you got fuel at all injectors when loosening the hard lines you may want to check the glow circuit. Still the injectors as you mentioned could be gunked up but that would bring up the question what was in that fuel you brought. You fuelled from high volume diesel locations? I always do if at all humanly possible. Those occasional small volume diesel fuel sellers are always a risk. I had more than enough experiences years ago to stay well away from them.

A few weeks ago My GP light blinked once on starting, but hasn't since. I've replaced all the plugs in the last 10k.
If it is the problem could I do the ground test where you see if current is getting to the plug for an applicable test? What other test are there? My dash light hasn't blinked since a few weeks ago. Edit[ The GP light still comes on when I turn the key though]

Quick test, make sure all plugs individually less than 1 ohms.
Before doing that have someone turn on the key and check for the presence of 12 volts on the glow plugs during the interval it should be there. Last edited by whunter; 10-23-2008 at 04:12 AM. Reason: technical correction, less than one ohm |

When you say the plastic filter was the only filter, are you saying that you bypassed the secondary filter? Or, are you saying you just went back to the OE system?
I would check the glow plugs--both for voltage and resistance.

Hope this doesn't make veggie haters not want to help me being I've gone back to diesel.
I've driven about 15k on a vormax fuel filters (R90T) which has a gauge for how dirty/restricted it is. The spin on filter was replaced with a heat exchanger so I only have had one filter. I have done diesel purges every 5k always run diesel with veggie oil and run tanks of bio diesel periodically. So yes I drove 70 miles with a small plastic fuel filter. I admit it wasn't a smart idea at all. Is it random that my glow plugs in one way or another went bad after this drive or is it related to praying on a single small filter?

It would just be random. Although you were getting some indicators previously that the glow plug system was already changing is some way.
As for the fuel people decide to use in their car biasing others with good sound knowledge from helping. I would hope this does not occur much. It is after all their engines they are risking. I wish I could convince myself of there being no risk. Just stuck in the mud I guess. Once alternative fuel uses are introduced to the trouble being experienced equation. It can easily complicate the issues unfortunatly. We usually pay substantually more for our fuel than Americans in Canada. It forces me to be receptive or at least examine approaches that might save us money. Rather than go to cheaper fuels for example that may or may not prove to be problamatic. We drive very fuel efficient cars for our general daily transportation requirements. Gasoline peaked at about 6.00 per american gallon this summer. Diesel at close 6.50. Reciently prices have retracted to gas at 4.20 and diesel at 4.60 per American gallon. If I had the time I would find out if it were possible to build some type of high tech battery like 123 of china builds at home and have the local fellows convert a small gas car to electric. One off battery purchases are out of the question financially. Other than maybe out of a wreck at some future point. Ninety percent of our driving is to town and back. A high teck battery could recharge in well less than 1/2 hour. The electric car range for this duty is more than adaquate. A direct current three phase motor is easy to build and requires only bearings for maintenance as there are no brushes. The controller for it soon can be sourced.

Any chance that the regular Diesel Fuel loosend what was in the fuel tank just like putting Biodiesel in a tank that had only diesel fuel loosens the diesel residue in the tank?
Also the stock Mercedes Plastic filters are 20 nominal microns. Other generic plastic filters might even have a higher micron rating and let bigger stuff pass through them.

Check the main fuse in the glow plug circuit (60amp) it may look good in place , pull it out and clean the ends , even toss a new one on there .
It went good , then stopped going , start at the beginning with your testing. You've got fuel , though the R90T filter seemed to block quick, perhaps the tiny one has plugged also, thats going to be easy to replace, now you need heat to start.

Wow driving one of those fancy rental cars back to Tahoe was intense. My foot has lost all sensitivity from driving bertha from the last year. I even managed to get a ticket My shocks on my motorcycle just went so I guess things come in threes.
Its a bit cold out side but I'm going to start and do all the helpful glow plug test as mentioned. Thanks for the help eveyone. I'll post results.

I'm not able to go into town to pick up a volt meter till 12...
so I detached a glow plug and found that my dash light didn't blink when it should have. It did blink when I removed the fuse. Light didn't turn on at all when I removed the GP connector. Could any one tell me what this means?

It seems that all my plugs are gettng 12v. Ugh it takes forever to get all the plugs out and check them inividualy.
I also cracked all the Injector lines and had plenty of fuel come out. I'm a bit lost at the moment. any other ideas?

Any more ideas?
Recap of non starting 80 300td stranded in the mountains
Drove 60 miles car lost power and R90T fuel filter was in the red. Drove 70 miles on small plastic filter. Diesel Fuel, with possible filtered veggie oil residue. After Sitting for two days car would not start. Turns over with smoke. Two weeks ago Plug light blinked once, but doesn't blink now. Haven't had any problems with starting till now. last 10k new battery and all plugs. Valve adjustment. Compression 2 at 320 and 3 at 410. Diesel purge. Car has been driven on Veggie oil, B2, and recently mainly diesel. Voltmeter test Power to Fuse, Power to Connector with lower ohms. 12v to all plugs during cycle. 12v reads on plugs from +term to tip with wire removed. Dash light blinked when I removed 60 amp fuse, and it did not light when I removed connector so I assume its in working order. Tested pins on relay and got twelve V's when key is turned in glow position. Fuel test Fuel at all cracked injector lines. Small plastic filter was still clean, but I replaced with R90T vormax filter system and purged air. Bypassed fuel system with can of diesel purge at IP and no start but was getting sucked out of the can. No go with diesel starter fluid either. Bertha seems to smoke less now after all my tests. Any ideas what I'm missing? I ordered new injectors that seams like my gut feeling. Thanks I really am feeling defeated but I know I'm missing something
