Autozone: AC40 (Has five pins but will work. This is also a Ford heater relay)
Installed Standard Ignition part # RY117 last week. Thanks to this thread, I was suspicious of these newer units and mounted it on front of dash. So when it failed the same week, I was able to unplug it before anything fried. Am going to use a glow plug solenoid as suggested in this thread. Glad it was me driving and not one of my crew.
Ignorant here.
I read all this stuff ~ CUCV s partly in hopes of learning, for one thing,
What is a CUCV?
So far I am guessing, mostly from the color illustrations, that a CUCV
is a light vehicle ~ pickup truck or SUV. But. Just a guess.
Does anybody want to volunteer a vague definition of "CUCV"?
Thanks for your time, patience and bandwidth.

The Commercial Utility Cargo Vehicle or CUCV Program was instituted to provide the United States military with a cheaper vehicle to augment the purpose-built, but expensive, Gama Goats and Humvees then coming into service. It initially provided Dodge D Series and then Chevrolet C/Ks with several military modifications. All were phased out sooner than expected due to their inability to survive the hardships that the purpose built vehicles could endure. The vehicle has five basic configurations; cargo, utility, ambulance, shelter carrier, and chassis. The vehicles were purchased in the late 1970s and early 1980s from Chrysler Corporation, Dodge Division, and in the mid 1980s from General Motors.
This forum is for the most part for the Chevrolet C/K. I don't know if I quite agree with the "All were phased out sooner than expected due to their inability to survive" since they are still in the process of phasing them out and they are still buying a few of the new version from GM. When you are making do with what you have you shouldn't be surprised that when you have a pickup truck and you need a APC that it doesn't last too long.

I left out the info that didn't apply to CUCVs on purpose, but it doesn't hurt to have the complete list on here. Who knows, we may see counterfeit cucvs one day. Thanks for the info and welcome to the site.
Troubleshooting an injection pump no start complaint
In order to properly troubleshoot a Stanadyne DB2 application, you must insure the following conditions are met:
1) Voltage – You must have the correct voltage to the shut off solenoid and to the cold start advance solenoid.
2) You should also have the pump properly timed. Please refer to the manufacturers timing information for complete timing instructions in the tech manuals.
3) You should also have a solid stream of return before the pump can achieve starting capacity. Return can be measured here. You can also attach a clear line to check the return for air bubbles here.
4) You should also have a minimum of 150-200 cranking RPMs. If your batteries are weak and you are not attaining the minimum cranking, your vehicle will not start.
INJECTION PUMP BLEEDING
Once you have satisfied these four requirements, the injection pump should be bleed. This is best done by attaching and properly tightening the lines at the head of the injection pump, and loosely attaching them at the injectors. As you are turning the vehicle over, you will begin to get a fuel foam, a mixture of air and fuel, coming out at the line connection, at that time go ahead and lock down the line nut to the injector. Repeat procedure until all lines are bleed completely.
If after doing this procedure the vehicle does not start, please do the following:
1) Attach a clear line to the return side of the injection pump and inspect for air bubbles. If you have air getting into the system, correct the problem before proceeding.
2) Attach a hose directly from the injection pump to an alternate source of fuel. You will need approximately 2-5 gallons for this test. You will need to bypass the entire fuel system, including the lift pump, for this test to be done properly. The injection pump has an internal supply pump that will pull fuel from the source.
If there is still a problem consult a diesel shop about rebuilding the injection pump.
