Bad motor mount/trans mount has shown me the two and twist differently in reverse than in forward. So when idle and going forward no issue but when loading them the other way :
Possibly pinched fuel supply or return line?
Possibly tension on wires disconnecting a little?
Possibly shorting wires...
Ok- after the 3 time key cycling: did it still start very poorly or did that make it a faster start?
I don’t remember - have you tried plugging in the block heater to make it start easier? If not, you need to do this. This will tell us it is a glow plug issue because heat solves the problem...
Yes, that is why Rocker arms will move more than others, because of the tension from the camshaft in the springs.
However, I would replace those plastic pushpins at a minimum. Better yet is doing the modification of replacing them with a bolt and a mechanical lock nut. Best option if you can...
The dimples reduce drag of air around it- proven from golf balls to a car.
But how they help on top of a piston and not air going around the outside of the surface is a hard question.
But there are dyno tests where only the piston was changed and improvements were had… except I haven’t seen...
The only ESS that exists in the 6.2/6.5 world is the Engine Speed Sensor- a component that went away by time the ds4 was in use.
That ESS as a shut down is incorrect for this platform.
Due to the oil loss scenario - first thing I would check is oil flow and pressure at the oil hose that feeds...
Idk the aerodynamics of under the truck, especially being lower to the ground.
Hoping the is a secondary cooler to a main up front. If not I would strongly suggest going up there with it.
Ok- ds4 barely getting fuel, appears to leak down due to bad check valve as AKDD pointed out, and takes a while to build that amount of pressure…
Cycle the key 3 times through the glow cycle, while watching the fuel pressure gauge. Then start. Please describe what happens or make a video of...
Your glowplugs are EXACTLY what I had and where I bought them. And I used to recommend them- until mine destroyed my engine. And saw multiple others having the same problem with them from Rock auto, and other sources.
Rockauto is supposed to be an authorized dealer for AC Delco now- but I...
Yeah- the new cameras take photos with more pixels so that it’s more clear, especially when zooming in. So it’s too much information.
But if you do a screenshot of the pic - that will post.
100% pull them.
Ohm test, amp draw test can be flawed- I proved it.
Gp can become crystallized, which raises ohm.
Swolled and or burn off small amount of the tip- either of these can lower ohm.
Ohm changes causes different draw (amp change).
I have tested GPs and had good readings which...
AK DD has it right. DON’T ground the light, make sure any of the mounting screw do NOT complete a ground to the light. Only the two wires in the connector- one to your power source the other to ground.
For the signature line: scroll to top of page and you will see your meme- the boue circle with B in it. Circled in red in pic (but mine is of my hummer)Click that.
Then a page will open, scroll down and you will see the word “signature” (next pic- circled in red) click that. Then you can type...
