Anyone else have an idea?

That's what I figured... That's why in posting and trying to figure out what's going on.

Because the truck starts fine with the gpr unhooked (it's still warm out) I don't think the gpr or glow plugs are the issue. I also disconnected the two smell wired and jumped power to the gpr and it does click on.

It is a gpr not a module. The truck runs fine when the gpr is not wired in so I know it's not the injectors. When it starts up with or without the gpr plugged in it works fine. However, when the gpr is hooked up it acts like the fuel pump isn't working and just won't fire. When it does hire...

You cannot hook the two small wires up wrong on the GPR if one goes to each post correct? There were no instructions in the package and I figured they would both be isolated from ground. Other codes that came up were in the "GEM/Central Timer" section: B1352 Ignition Key-In Circuit Failure...

So I am trying to help a friend fix his truck (early 99 7.3 PSD). It wouldn't start when the temps are 40 or less without the block heater. I checked the GPR and it turned up bad... it would click as if working properly but pass no current through it (constant 12V across the big lugs). Glow...

Sweet. That should settle it for me. Thanks

Ok. Thanks. I understand that there are different tunes for auto/manual.... what I was really wondering is if I get a chip out of a manual truck CAN it be reburned for an auto truck? You did answer my question about the $$ though.

I'm looking at buying a used DP F-5 Chip. Right now they chip is set up for single shot injectors and a manual transmission. I have an automatic and splits. Is this something that I can have changed over (are all the chip blanks for manual the same as auto?) and if so how much do you charge...

So what kind of MPG are you guys seeing with your single shot 160's? Please also specify whether 4x4, auto/manual, diff gears, and highway/city, and towing/not if possible. Everyone keeps telling me that single shots I am going to see 1-2mpg better than stockers... but is that because they are...

This drop in MPG is not just this winter... it has been lower ever since last winter. My truck just turned 200k and as far as I'm aware has stock injectors. I built and did a blowby test and my truck passed with a reading of 2.8"water (I was told 4"water max is the limit for a healthy truck)...

If my MPG has dropped since last year 16-18 down to 15 or so all summer/fall and my truck is starting to smoke a little more on startup, is it likely that my injectors are just getting worn or I have a cracked tip? The other possibility that I was thinking is that with the smoking on startup...

I do have a permanent Isspro fuel pressure gauge installed post filter. Even in my top setting my truck still maintains decent pressure (well within range). Typically my truck runs 60-65psi and the regulator is still stock as far as I know. Drilling the banjo bolts is enlarging the holes in...

That sounds reasonable to me. I don't know for sure and had never heard of it before until recently. It just seemed less likely to cause cracks than EDM.

I am not sure of the exact material they are made from but I would guess its likely that after the tips are EDM'ed in production they undergo some form of heat treatment to increase strength and prevent cracking. If someone were to EDM an old tip to modify it and did not perform the proper post...

OK. My biggest concern was damage to the engine by running the singles without a tuner. From looking at Unlimited Diesel's website I am definitely not going with their injectors as the nozzles are EDM nozzles. I talked with Jim from Rosewood and some other people and that is old technology...

Is anyone running swamps tunes too? They offer free retune with their injectors. Just wondering how their tunes are. Is there any concern about going to single shots and then having trouble with the tunner or getting retunes? One concern I have had is not being able to drive my truck if I...

Who did you go with for tuning. I'm trying to decide where to get my new injectors from. DP (full force) offers 165cc/146 single shot for about $1100. However I was also looking at Swamps and they have a 175cc/146 single shot for $1600. Which place is going to be a better place to get them from?

Thanks. I don't intent to race or sled pull with my truck. I just want to get a little more power for pulling an enclosed trailer. Would I need to upgrade my fuel system any more than it already is? I have drilled banjo bolts, fuel bowl safety parts deleted, and running two in-line fuel...

I already have a set of good cores sitting at home. They were pulled from a running truck and had about 130k miles on them.
