I am cosidering the option of converting my 97 K1500 from a ds4 to a mechanical db2 pump. The electronics have given me alot of trouble and I am getting tired of it. Anyway, I was wondering who has done it, and if there are any 'write ups' outlining the necessary componets and wiring. I have the manuals and I could figure the whole thing out if I had too, but if someone has already done it and has the information it could save alot of time.

Thanks for your input. Brent Hi Brent welcome to The Diesel Page!! Since you are a newbie why not tell us about your troubles and see if we can help you with the DS-4 first before you go through all the hassel and head aches of converting to an DB-2. DB-2 have shorter usefull life I have been told. I have over 175,00 miles on my current DS-4 pump.
Is that good life? Now I'm not saying there are not some problems,but many people have tried different fixes with mixed results. Tell us your trucks story!

Diesel Page member #81. 16ga, I couldn't agree with you more. While the electronic pumps have given trouble, there's been a lot of good ones out there, and they have been improved over the years. I like the quick cold starts, electronically controlled idle speed, and the fuel economy provided by the DS-4, and would NEVER care to swap backwards to the DB-2.
The DB-2 pumps have not been without problems, either. One irritation I have with them is the poor durability of the advance piston and bore. Proper long-term operation of those parts is crucial to good fuel economy and power. BR455; Fist please go to the user CP and fill out your signature with your truck year and info see mine for an example. Please also tell us about how many miles are on your beast.
First thing you should do is CHANGE your fuel filter if you had not. The cost from $15-40 depending where you get them an all seem to be made by Stanadyne so quailty is the same. Second go over all your electricals AGAIN grounds included clean them and maybe even get some electrical cleaner spray and take all the plugs apart and spray them.

Here is a link to a trouble shooting area: This is a 'members only area'. If you haven't spend $20 and join, the resources have saved me thousands over the last 10 years. Between the subscription and ad's it keeps this great place going for us for the last 10 years. Now if your stalling keeps up it could be the ill fated famous PMD/FSD problem. Start taking liter of bottle water with you. This is a black square driver mounted on the iNjection pump.
If it stalls again and if it is the PMD/FSD it will when it won't restart pour water on the PMD/FSD or put snow or ice on it. If it starts up it's very good chance that is your problem. If thats the deal do a search for PMD/FSD and you will get a weeks worth of reading.

Your truck being 4WD with OBD II makes the swap a bit more complicated, but it is possible. If its an automatic, its a bigger challenge, manuals are pretty easy. As for the problems with a DB2, yes they can break. However, I don't think you will find anyone that has even a basic knowledge of the two pumps to tell you the DS4 is more or even as reliable as a DB2. One thing, when the DS4 fails (usually without warning) the truck usually won't run. When a DB2 fails, it usually will run, just maybe not perfectly. There is no reason a DB2 equipped 6.5 cannot start, idle or produce the fuel economy of a DS4 equipped engine.

I'm not saying a DB2 conversion is the solution to your problems, but it may be worth considering. The DB2 lets you eliminate the APP, vacuum pump and related wastegate plumbing as well for even more reliability. The are plenty of products on the market to 'fix' the DS4. I don't think they would be selling in the numbers they do if it were the paragon of reliability some would have you believe.
I've driven both for about a hundred thousand miles each. I much prefer the DB2. Others like the DS4. One more thing, I'm certainly not against technology, just unreliable technology. If I thought the DS4 was the best way to go, I would still have one. Our new car (we still have the Sub) is a VW Jetta Diesel with Pumpe D.
