Shuts off while driving - Stalling

[skidoocam]

I just joined this forum to figure out what is wrong with my 6.5L and I am also having problems with it shutting off when I am driving. I took it to the dealer and they said I need a new fuel pump and lift pump! Does that sound right? It runs fine most of the time and, with my budget, would be pretty disapointed if it kept doing the same thing after I bought a new pump. I saw what Ranchman said about the DS4 Solenoid Driver (What ever that is) and check my recipt and it said "Code 35 stored in history" So I guess I will try and replace that thing first. Could someone tell me what the PMD/FSD is??

This will help you get a better understanding.

Thanks I figured it out after a little more poking around the site. I changed the FSD and so far so good. Time to sell it I think. I tried to click on that link and my password didn't work?

Hi Skidoocam

My username and password are different when I log on to the member's list from the forum. Check that out in case yours is too. As for selling the truck check out the after market FSD and coolers out there first. That's the only problem I had with mine. Replaced it twice in ten years under warrantty. Can you give me your email I need to ask you something concerning ski-doos.

I don't get this plug and play on the SOL-D.
The SOL-D that came to me was a plug and play.
And is running far better than any FSD I have went through.
I know I have more power,less smoke.
This talk about RemarQ just floors me.
I've talked to C. Stan and Chris and they were two of the best guys I have dealt with on this SOL-D.

Subject: Return of SOL-D unit. 12/10/2004 9:26pm
Barry,

I am sorry for the delayed message. We regret the inconvenience and we will do our best to ship you a replacement unit early next week. Following the first failed unit sent for evaluation to the Diesel Page, we implemented an extended overstress burn-in test for all SOL-D units in house. Unfortunately, your unit did not go through this process, as it was shipped earlier. This new process created a significant number of back orders. we stsrted testing your unit with a higher priority,but this will not be done before Tuesday (we do cycle the temperature from low teens F to about 220-240 degF, while running the SOL-D at high load given by maximum RPM equivalent physically possible.) The procees is about double the effectiv 72 hours burn-in.

This weekend or at the lates on monday,we will send to Jim Bigley (for publishing) our investigation report about the three units we had received. we do not want to guess the failure mode of your unit,but the three failed units had the same symptoms and same cause. We want to be fair to all our ustomers and potential customers, in presenting the information from a single source and at the same time. Be rest assured that we will get back to you with our investigation report about your unit as soon as we have it available.
C. Stan RemarQ

It is our privleg to serving you and once again we apologize for the inconvenience the SOL-D failure has created. We will be replacing your exixting SOL-D with the latest manufactured one as soon as we will have them ready.
Thank you for your business.

Sincerely,

AS I have said my # 2 unit is one of a kind

I had the same thing on my 1994 GMC, it would stall under acceleration but then start right up. No codes were set. The problem was the inejection pump, dealer changed it under warrenty.

Read about stalling on this forum. It's very likely that your dealer changed the pump when all that was wrong was the FSD. This is the standard dealer approach.

By the way... Welcome to the forum!

[Iain]

Thanks for the welcome! I was lucky as I was just under the warrenty limit of 193000 km. I figured if they wanted to change it all out, might as well get a new pump in the process courtesy of GM. I did add an FSD Cooler kit so as to keep the FSD alive for years to come.

I am having a similar problem with my 96 Suburban It runs fine and stalls takes 20-45 minutes before restart is possible have noticed that the Glow Plug lite does not come on when the restart is attempted but it will flash several times when the system allows a restart it is not a PMD as I have replaced them twice during the last 3 months and when the failure does occur the PMD temp are at 60 -70 degrees F and no codes are showing up on the scanner. This problem has occurred when I start the truck in the mornings.Am I looking at a PCM failure or an ignition switch failure

[rjschoolcraft]

Two things are most likely: ignition switch or glow plug relay.

Since yours is stalling first, it is most likely the ignition switch or connections for such. Check all of your grounds and connections (see This Article in the members area for more information), then check the switch.

I had a glow plug relay problem once that caused a no start problem similar to yours. The glow plug light would not come on and the truck would not start. Repeat tries would eventually get the light to come on, then the truck would start. However, this did not cause a stalling problem along with it. Therefore, I would first suspect the ignition switch.

Thanks Ronniejoe will check out wiring I have eliminated all other potental causes
Thanks again

later

I asked about business refereces and phone and address for this guy and he refused to provide it. Also check out this guys return policy basiclly there is none. STAY AWAY FROM A-1.

I have not purchased it. I was thinking about it but when I mentioned A1 customs on the forum I got a few negative feedbacks therefore I will wait on that. I started looking at Remarq (SOL-D) but not impressed with the reviews I read so far.

I don't blame you the SOL-D has not proven to be reliable yet. I went with the Heath PMD Isolator kit every thing you need and Heath Diesel backs it for 7 years and Heath has been working on Chevy Diesels since the 6.2 Diesel days and you can talk to Bill on the phone and his word is his bond. I first tried the Beta cooler which the A-1 is a knock off of. There are other options that may work.

[Eddys]

Hi 16ga sxs

You bought the Heath PMD Isolator kit does it include a new PMD or just a heat sink and how long have you had it? As A1 customs I'm definetly not buying from them either. It's impossible to talk to someone on the phone over at A1 because they won't give out their phone number. I found that strange.

[Marty Lau]

Hi Eddys;
The Isolator kits comes with the PMD/FSD mounted on a the heat sink plate, 6 foot extension and mounting kit. I have had mine under 2 years and have 35,000 miles on it. Be sure to tell Bill your a Diesel Page Member and he MAY give you a discount. If you do a search for Heath you'll find out what the folks that have dealt with him feel about doing business. I think Heath and Kennedy are our two best 6.5TD vendors, they both stand by their products and are very helpfull. Both own or have owned 6.5TDs and their shops work on them regular. Hope this helps.

If you get the Isolator you can leave the PMD on your pump and use it as a spare so that if FSD/PMD on the Isolator craps out you can plug into the PMD on the pump till you get a replacement.

[Eddys]

Thanks for the info 16 gauge.

I got another problem now with my pickup 1996 Z71 with a 6.5TD. This truck is driving me nuts. It could run fine for months and then the engine lights up. When the engine lights up it could be on for days with no performance problem and sometimes it might stall and start up again but with no power. Last week it stalled while driving and the engine light came on. Was able to start it but then stalled again and unable to start it. Left parked for two days. Tried again on Monday and guess what no problem engine light gone and rides like a champ again. I had brougt it to GM the first time this happened and they changed the fuel pump that was two years ago. A year later same problem. GM this time changed the PMD and seemed to run fine. Only lasted a month then engine light came on again. The truck still performed well despite the engine light. I then called back the dealer and brought it in and with the scanner on they were not able to find anything wrong. The light went off and did not come back unit last friday since early summer. Is there a way to read the codes without going to the dealer? I'm also open for any suggestions?

[rjschoolcraft]

Have you read this Turbo Tips article? This article addresses many other issues that can cause this problem.

I, too, am having this stalling problem now. My pump was replaced at 90K miles, but I now have 155K. The problem just started this week. I replaced my lift pump already. It stalled again this morning. I have noticed that it does not matter whether I am accelerating or just parked in the parking lot, it can stall. It always starts right back up with no extra cranking. However, when the engine is good and warmed up, it does not stall. Only on short trips around town does it happen. No light comes on for check engine. I went to a mechanic today and paid to have him check for history codes, and his scanner said there were no codes to report at all. I did notice that the fuel shut off solenoid (silver tube you can put your hand on in front of the injection pump) seems a bit loose; not a lot, just a little bit -- is that normal? Should I replace the PMD? Please help guys. This is a lot of money. Thanks.
Adam

[Marty Lau]

Adam;
There is a check list of items to check and work on before replacing the PMD. Do some looking around you'll find the thing to look at like, clean and check all grounds, the OPS, ECT. If you have have a small cooler put sone ice in it if it quits and won't start put ice on the PMD and if starts right up it most likey that.

Hi RonnieJoe

Thanks for the tips I read them and will definetly try them. The truck rides great again and for how long nobody knows. It's been two weeks since that mishap and still runs strong without doing anything. I'll wait until spring when it gets warmer to do the work since the truck does not fit in my garage. I have to work outside. It's still cold here in Montreal. It's -29C with the winds today.
