Mmmm... The oil level is not higher, corelokt. I went ahead and changed the filter, because I had a new one handy. I cannot get fuel to come out the bleeder on the filter housing. Drained the batteries trying. Charged them. Tried again for some time. No fuel coming out. The fuel pump...

Thank you to you all. So, if I get it... a thorough examination of lines and then more complex things like injector pumps and fuel pumps. Any small leak will let air in and that will allow the fuel to drain back to the lowest point: the tank. The ultimate solution might be to replace all...

Hello troops, 1984 M1008 CUCV Started easily, ran 5 seconds, and died. Now she cranks fast but won't start. No smoke. No fuel coming out bleeder on stock fuel filter when cranking for 10-15 seconds. I guess we're having fuel delivery problems here...think its time to do the spin-on fuel...

Yes, I believe the glow plug relay was the cause of the short. I had found that with the truck off and the ignition key not turned at all, the glow plugs were still getting 12 volts.... seems like the relay was stuck "on". The symptom of the batteries draining to 5 volts within an hour or...

Hello all, Thank you very much for your expert guidance. I have replaced the glow plug relay (after checking continuity between the various terminals and the mounting tabs) and I also replaced the starter relay as per the Doghead Relay mod instructions. I also bypassed the glow plug resistor...

cfp240: I will make the continuity test you suggest on the ST-85. Thanks to you and Rich for your guidance, GentleGiant

Hi Rich, It seems that NAPA ST-85 is recommended on several threads here as the proper relay and also it is mentioned in the CUCV Wiki: Glow Plugs DH recomends AC Delco AC60G glowplugs and installing new 1/4" terminal ends on your wires Wellman 070 (original 3/16" terminal) direct fit...

eme411: no, I've had this truck for almost 10 years. cfp240: I would like to be sure I know what you mean by "electrically isolated". I plan on getting the st85 relay at NAPA tomorrow and swapping it with the identical looking one currently in the truck. I would make sure that any...

Hello CUCVRUS, I do have those covers, and they are re-installed now. Thanks for your concern. GentleGiant

Thank you to all responders. I have removed the suppressor and I appreciate the prompt and clear information from you all. Again, this forum impresses me. Sincerely, GentleGiant

Thank you Rich, I will replace that relay. ST-85 appears to be the correct number, as I have seen it elsewhere on the forum. I am impressed with my little Canadian small-town NAPA for having it in stock. I do appreciate your suggestion to look at the stickies, etc... I spent a few hours...

Hello All, Looking around the electrical system to better understand it, I found what looks like a bad suppressor. Its a little connector between the positive and negative terminal junction blocks. Here's a pic or two: My questions are: 1) Is that a good idea to replace that...

Hello and Thank you Rich, Here is a picture. The smaller red wire from the negative of the rear battery turns blue and connects to a two-studded part on the firewall before getting to the relay. I think its clear in the picture above. Interestingly it connects to the left stud, and the...

Thank you again, I disconnected the leads from all 8 glow plugs. Gently started hooking up the batteries. No spark. Tested voltage on a glow plug lead with key not turned on: 12.8 volts. Ah-ha! So, not that there can't be two problems at once, but it looks like the glow plugs are a...

Thank you for replying, kind sirs. Is it 24 volt? I certainly believe so. The batteries are connected positive on one battery to negative on the other, so they are in series and that must mean 24 volts. I apologize about the ammeter.. it was late when I was writing and upon examination in...

Hello: 1984 CUCV. Drove home yesterday, no problem. Changed the oil. Near freezing point this morning. Started it without plugging in block heater... running a bit rough in the cold, but running... then stalled. Didn't want to start again, so I said, "OK, I'll plug you in." Plugged in the...

Hello friends, My '84 M1008 has problem with the front battery draining down very fast. BATTERY: I had this same battery problem in the Spring, and let the truck sit in the barn over the summer. Today, it started right up. There is no battery drain while it sits. While the truck is...

Thanks, RickF, Good detail to know!! I didn't hit it very hard, but won't do it again.

Thank you 998Junkie and RickF for your quick replies. I was tending to think it was probably something like the crankshaft, but I thought I'd try the bad battery idea first. I charged up the battery that is in there (probably does need to be replaced, but it took a charge), and tried...

Sounds bad to me. Here's the story: My 1984 M1008 sat in the barn over the winter, and last week I finished changing my glow plugs (many thanks to this forum for helping me with that). The truck started perfectly. I warmed it up and changed the oil. Then I did a few runs to pick up some...
