Yea I just e mailed him and asked how about to go about shipping the pump. Thanks for the good suggestions. I think I still have the rubber caps also. Thanks guys I let you know.

Thanks guys for the help. I believe I will send it back and have it checked out. I hope he has mercy on me about the warranty expiring. I did send him an e- mail w/ that Stanadyne bulletin and that I hoped he would work w/ me. Haven’t heard back. I’m going to e- mail him again and ask him what...

Would I be able to tell if a rotor was install wrong on a newly installed remand DS4 IP if I opened it up? I believe you have to line up some dots or marks when installing the rotor. I suspect I have a bad pump and also by reading the Stanadyne bulletin #502R Section 5 on the last page. My...

If QS fails me I’ll open it up and check it. If I can’t fix it I’ll try to find a more reputable pump shop and have to buy one. And use this one for a core. At least I have a good running pump. Know of any pump shops that rebuild in house? Thanks buddy.

Isn’t the rotor one of the parts discontinued. Maybe they ran out of the good ones. Yea I agree that’s why I probably will send it to him in case he hasn’t seen it before.

Wouldn’t it be a good idea to send this to QS when they check the pump out?

Also found this. Both my pumps are 5521. It says the 5521pumps are for 00’,s . Mine should be an entirely new different pump number. Or am I missing something.

I was scrolling through Stanadyne service bulletins and found this: https://www.dieselplace.com/attachments/stanadyne-ds4-service-bulletin-sb-500r2-pdf.380602/ Go to section 5 engine diagnostic my truck is doing the exact same thing w/ the reman pump on and throwing balance codes. Won’t show up...

I just got done putting the reman pump back on and will finish putting the intake back on tomorrow. The reason I’m trying the reman pump again is that I might have had air still in the system the first time I put the pump on. I say that because I had forgot I left the drivers side injector lines...

Hi all, just got a reply from QS. He said the pump is technically out of warranty. I could send it in for inspection and they could see what they find. Said it would have to be torn down and resealed before even hitting the test bench $500. He did say he could work with me as much as...

I thought I mentioned in my post that the new pump was a reman. I read some where the reman pumps come w/ red ID plates. Still curious if my original pump was opened up at some point because of the white sticker. I still haven’t heard anything back about the reman pump. I called...

Did you take look at the TSB. It’s very confusing to me. The new pump and engine harness seems to be the original design (as per TSB) and my original pump and engine harness and PDM extension harness are the currant design very confusion. Shouldn’t it be the other way around? Here’s a pic of my...

Looks like I’ll have a little time before I go to the 60g GP. I e-mailed QS about the reman IP not running good on my truck and e-mailed a video of the truck w/ the original pump on. Also he said the scanner data I sent him previously had good pump timing numbers on it and didn’t...

Thanks guys, can you tell if they are self regulating GP,s without pulling them? When they turn on they run about 6to7 seconds then if I turn them on right away they only run for a second. Are they still in danger of swelling because their no marking son them? The motor starts cold w/one GP...

Thanks guys, yes I did talk to him about my truck running bad and e mailed him videos of engine data and w/my truck running badly w/ the new pump on. And he e-mailed me back w/ some suggestions. Yes he seems to be very helpful. He e- mails back all the times I had questions. I’ll send him the...

Hi all I just finished up installing my original IP and did the Time Set and the TDCO offset learn. I use a ECT fooler because I had drained the coolant out to remove the intake and didn’t want to put the coolant back in because I was going to take the intake off again. It started up with no...

Thanks Marty, I think we’re on to something on the GP ,s. I just thought that having the correct amp readings on the GP harnesses 100+ amps on both harnesses and 50+ amps on just one. Along w/new GP and new harnesses was enough to start these motors. I was reading up on the GP systems on these...
