Hi I recently purchased a 2001 3500 - 4x4 - 6 speed manual - quad cab. 

 

It has just under 98k miles on it.

 

It has an edge tuner, banks 4" exhaust, Banks exhaust brake, pyrometer gauge and turbo boost gauge.

 

It had a quite a bit of differed maintenance and a few needed repairs so I'm getting that all caught up first.

 

The check engine light came on 2 weeks ago and I pulled P1693 + P1690.  The truck was running but seemed a but sluggish at the time.  I changed the fuel filter, which was really grungy.  I cleared the codes and measured the fuel pressure which came in at just under 15 psi.  I also changed the air filter.  I drove it around for a bit and it seemed fine.

 

This week I had the oil changed, the cooling system flushed and the brake fluid changed.  All other fluids were already changed.

 

I ran some errands today and the check engine light came on again.  This time I got a P1693 code but could not pull any other codes with my ODBII reader.  I tried a reader at my local auto parts shop, nothing came up with that reader either.

 

The truck seems to be running fine, but I haven't had it that long so I'm not 100% sure what normal is yet.

 

Any suggestions would be awesome!

Fuel pressure gauge would tell more about that typically the stock system is too restrictive for even a stock truck. This why most of us have upgraded to an AirDog or FASS fuel system that replaces all the plumbing between the tank and the VP44. The only thing I would suggest is that you keep the stock filter and not remove it. The idea of double stacking filters is good also the WIF light will continue to work and fuel heater in the bitterly cold winters. 

 

Back to the topic title of the solo 1693 code... We need to pull codes and see where we are going before we buy a bunch of parts that do nothing for your immediate problem. 

No doubt!  I've gota get my battery terminals squared away as a first step.  They are a hot mess right now.  The lead ends and bolts are compromised, loose, funky and can't be tightened at all.   I'm going to upgrade to crimped and soldered military terminal ends.  Then I'll go after the system wiring you gave me.  I feel like I need sound connections to my batteries before I go chasing down electrical issues.

 

First things first.

 

I have lots of other vehicles to drive around here so the dragon will sit until I can get some parts delivered up here.

Best way to handle it one step at a time.

Always first things first.  The only way to eat a Rhinoceros is one bite at a time.
