I agree
When I read that suggestion I thought but how could that be??
When I saw that wet inlet and could smell the R99, I knew all I needed to do was tighten that fitting and get it started and keep rpms high enough to clear the air. When the pump ran faster with the loose fuel cap I knew...
This is a disability mini-bus by Braun Mobility with commercial side mount condenser and fan and rear heat and a/c with wheelchair lift. It has custom wiring which may cause or contribute to the issues.
If you have a 2000 6.5 these glitches are gone from yours. From 97 to 98 starting and glow...
Well it is quite common and you can references to the oddity all over forums on the internet. On various vehicles it presents in different ways - but it is always the crank fuse.
Here is one such thread https://www.s10forum.com/threads/whats-the-crank-fuse-do.462149/

There is no reason to believe any of what you suggest is an issue.
The ecm / crank fuse pull and replace is common of that vintage gm vehicle though with the 6.5 it may crank and not inject.
There is no high current draw to the fuel...
As said - it has run six years with no problems until I replaced the lift pump and did not tighten the inlet to the lift pump enough and let it suck air - for three weeks at that
I also discovered the fuel cap not vented well enough.
Why that new PMD failed I am surprised at but also do not...
The PMD of course is on a heat sink - placed in air flow right at the hood opening and was swapped once with a new one before the issue was found that fixed it
A couple of things here:
1. Idle would not go below 750 even after it warmed up
2. It had a new #9 resistor when the previous was a...
It was easy to find because I did it to myself when I changed the lift pump after six years of no problems.
As a part of my troubleshooting I loosened the fuel cap incase there was a suction no flow issue. No evidence the cap vent was plugged plus I had already done the fuel cap drilled hole...
EPITATH
Was measuring wrong pin on pmd cable - nothing wrong there
Closed hood and cranked.
The I remembered sometimes when the engine shutdown, I have to pull the ecm and cig lighter fuses and put them back in before it will crank and inject to start
Stumble starts rely rough and I keep...
Yes I was going to put the resistor in the cable too but just too lazy. I have seen these in pmd resistors burn through or burn up the foil trace. I put in a new #9
It is van and it is hard to access the top of the ip

I may have found the issues
Fixed one - taking a break and I will do the cable, put a top off charge on the batteries and give her a crank - fingers crossed
Yes I know and agree. I have a foxwell bt-100 battery tester and they are still putting that out. I also have four more internal batteries for the tool inverter which full charged adds 3900 CCA for 6500 CCA together. I also carry a small 1000 watt generator and 200 Amp starter / charger in...
The new pmd drove and started this morning
The batteries are new not one year old. They are flooded agm and have 1300 CCA each
It cranks fast enough to meet the 200 rpm required to cause the DS4 to inject unless crankshaft position sensor is bad a d did not throw a code
I have a 1997 6.5 that started this morning and and stumbled and died. Now it is a no start. Fuel pressure is good - there is a liquid filled mechanical gauge at the IP inlet and it to 16 psi and holds. I swapped the pmd with a new one yesterday.
This started with fish biting and stumbling...
