@seanres - how did the new GPs turn out?
FWIW - agree with others about the top GP, its wrong. Doesn't really matter how or even why.
In defense of all the sellers out there (all recipients of my ranting)- they will not have the time to thoroughly inspect and verify GPs. They would have to dig deep in a place like this one to even find the information needed to do such an inspection. Reality - never going to happen. Even RockAuto has this problem (from experience).
As time has rolled forward since my truck becoming the _most_ reliable of my cars... I keep a complete set of "tested good" GPs. When I pull one or more out, I start searching for and buying more of them - right then. When they arrive they get a good inspection and bench testing before going in a bag labeled "New - Tested Good". I try to return the ones which do not pass - not always succesful (I get over it - just a cost of having the parts).
Almost forgot - bench test all the GPs that come OUT. Keep the ones which are not margional in a separate bag/box - label as "Known Good". Nothing worse than being two GPs short when its 20 degrees outside...
BTW - I've also long since invested in a cheap battery tender. Bit different from being stranded, but when the batteries get low enough to impact the ability to start... its time to put the wrenches down for the day anyway.

So the new GPs seemed to help but I have run into another issue. On the 29th, I drove the truck again with the new GPs and found the truck still not super easy to start. Drove it slowly in my area for 10mins at a time, running time total 2hrs driving time total around 30mins. Stalled it, had battery issues, and found I had a bad alternator. Could not start it that evening after driving it but figured it maybe was something else. I have not been able to get it started consistently since and I don't know why!!!!!
From my last post on the 22nd I have:
- added a water fuel separator in between the tank and the electric fuel pump
- upgraded the alternator to 3g and confirmed it to be working when I got the truck running a few days after the 29th. Since the 29th it has since started only once, but I have not used either.
- retarded the timing to being dead on the line (past few days while troubleshooting), when I drove it I slightly advanced it that morning to see if it improved running and it was better
- adjusted the idle to be 700rpm (on the 29th)
- new fuel filter
- tried running the truck off of an external tank from the electric fuel pump, wouldn't run w/ fresh batteries and 10s glow plugs, not even close!!!!!!!!
- cleaned electric fuel pump filter
- new return line fittings from the IP to the cross with a clear line
When I try running the truck, there is barely a trickle of fuel coming out of the return line from the IP from what I can see on the clear tube. My current theory is maybe the check valve is bad, or the fuel pressure is too low, or I have compression issues which showed up because of running the truck for harder than its experienced before, or the timing gear is actually misaligned because someone messed with the timing gear and I have never looked myself to see if it is correctly set.
Tomorrow I am going to try running the truck off of either and letting it idle to see if that clears up the issue, maybe put some ATF in the new filter and let it idle.
Any other suggestions? I'm at a loss!!!!!
