Our CCfan family!!!!

Sometimes I just can't believe how this site and the members have really interacted with my life. Yes, it truly is a family. I know of no other site like it!!

I got a very pleasant email today from Alan Arrighi (81nautique) regarding a problem I'm having with my 95 diesel Suburban. I may not have a tow vehicle to get my Atom to GL! Alan came out of the "blue" and offered me to use his Jeep Liberty!!! Yup, it wasn't even solicited! -- fantastic!!!

Here's the problem that Alan does know via some emails I've been having. My truck has been "stumbling" for almost 6 months. Almost like it's getting air. New lift pump on the frame rail and new fuel supply/return lines. No difference. It will run down the road for several hundred miles and then decide to quit!! New injector pump and ECM just over a year ago. Then, it would trip the "check engine" light. Now none!! The thing has only got the OBD version #1 so no real decent data comes out of the ECM.
It's been over at my diesel mechanic now since Tues. when it really "crapped" out on me, and OF COURSE, it starts and runs fine!!! I certainly hope its' not another Injector pump!! He's putting a clear fuel line in the supply and taping it to the windshield to look for air bubbles. he's also hooking up his reader and driving it all weekend to see if maybe it stumbles and the reader picks up something???

BTW,
The little Hyundaye (sp?) rent a car I'm driving doesn't have a trailer hitch on it. Damn!!!!

Was '95 the last year for OBD-I on the Suburban? I hope your guy gets you fixed up.

Eric,
The turbo is ok. I pulled the intake hose the other day and it spins great and no radial play. It's about the only thing you can do to check them.

Since the stumble is just like turning the ignition key on and off rapidly (not a gradual loss of power), my diesel guy is thinking more in line with another electrical issue. If the stumble is real bad, the engine will die but if I'm rolling down the highway I can slip it in neutral and restart it. (key to "off" not required) The injector pump is running on a after market fuel driver module. Stanidyne was having nothing but problems with their early versions so the after market went in years ago. It may be a good direction to look at as there are issues with the after market units too.

Ironically the firm I work for is a Stanidyne supplier of some of their stampings. We make literally tons of small metering orifices for their pumps. Every time I have a issue with my diesel, there's alway some smart ass at work that tells me the problem is due to the bad, out of tolerance reject parts we ship them!!

Pete, Its a long shot but check out the immobilizer on the ignition and key if it has one, I have a 95 runaround had the same symptoms but gas engine.

Yes but that switch and module are 15years old and I have found that late 80's 90's electrics are not as good as older parts, I know I'm going to get well chain pulled the way I speak and name things, looking forward to learn American English.

2 countries separated by a common language!! LOL

Ford ownership concept is pretty simple. Buy a Ford, own it until the warranty is about to run out and trade it for another Ford.

I really want to get my hands on a newer Lincoln, the wife needs a car and a guy was in financial ruins and wanted to dump his Camry cheap...I just couldnt the trigger..

if you buy a Tundra over one of those bad ass looking fords. they are a nice looking truck

Pete i was a diehard fan of GM diesels, had four of them over the years.

Two years gone and i'm still afraid to add up all the receipts on the '96.

Too bad you have an automatic and need the computer, else just throw a '93 DB4 mechanical pump and spring wastegate and drive the eff out of it.

Those engine were fabulous when they were 2-wire engines, but '94 up just too fragile of engine management and injection systems. All it takes a bit of debri on the optical encoder and bam, new pump time.

Big monkey off your back when you finally let that one go, big relieve not dreading the SES light or sudden loss of all power, steering and brakes.

I know, they run great when they run, and not everybody needs a 400hp monster that appears to be the only alternative now.

But we'll talk you down....let it goo.....

Have you driven an 07 or later Tundra with the 5.7L Engine and six speed transmission?


Looks like Toyota wants to get into the diesel market too. They have been talking about this since for a few years. I think the problem is getting the emissions in check and finding a market in this economy.

Pete- I'm glad you were able to find a tow vehicle to pull that beautiful Atom to GL, I'm really looking forward to seeing that one.

Yes and it totally reminded me of a Moped, and you know what they say about Mopeds, they are like Fat Chicks, Fun to ride as long as your friends don't catch you on one!!

I learn something every time I visit this site... never would have thought algae would grow in diesel!

I'm in Todd! Just filled up with some high octane rice, let's go! Looking forward to seeing you again this week. Can't wait to get there, I need a change of scenery real bad!

Todd,
The algae issue was discounted along with the fuel lines sucking air someplace. What he does is tie in a piece of clear fuel line and tapes it to the winshield. Then he can monitor the fuel while driving. No bubbles!! He really didn't think it was a air issue anyway. He said if it was, then the engine would lose power gradually. This stutter is just like turning the key on and off rapidly. Sometimes even staying running. Other times when it has completely died but a shift to neutral and then a restart.

It's also a daily user so it gets fresh fuel every couple of weeks. (42 gal. tank)

Thanks for the idea though.
