Installed IP = NO START
Yep. Thats it. I put the IP back in and had the dampener mark at TDC. and the IP timing mark on the gear was at the 6 oclock position. Now it wont start. Im not sure if I was at TDC of compression stroke or TDC of Intake stroke. which one do i want and how can i get there. I really need help. No work can be done with no work truck. hopefully yall can help. PLEASE
I think he may have remove the cover......only he knows for sure....
The timing mark is found on a little plate that is on the front of the engine on the passenger side. The plate is mounted so it is very close to the main pulley on the lower front of the engine which is mounted on the vibration damper. On the side of the vibration damper, is a line, which when lined up with the line marked (O) on the plate, tells you that the #1 piston is at TDC(top dead center) You can see the line on the damper, and it points to the line on the plate with the (barely visible)O mark on it.You'll have to find a way to turn your engine over by hand (Crank/harmonic balancer bolt). Make sure you remove the power wire to the injection pump(so the engine won't start)and then rotate the engine until you can line up the marks.
The engine rotates in a clockwise direction as seen from the front of the truck, and for every 1/4 turn of the engine(crank) each next piston will arrive at TDC. So, When the line on the vibration damper is at the 2 oclock position, cylinders 2 and 5 will be at TDC. When the mark is at the 5 oclock position, cylinders 7 and 6 will be at TDC, 8 oclock has cylinders 3 and 8 at TDC, and back to 11oclock, 1 and 4 will be at TDC.
Cylinder numbers are assigned 1,3,5,7 on the right (passenger USA) bank from front of truck to back, and 2,4,6,8 on the driver's side (USA), front to back. Firing order is 1,2,7,3,4,5,6,8.
OK all the above is true...... to ensure the #1 piston is at TDC compression remove the inspection cover on the oil filler/gear cover. You will see a dowel pin from the IP if it is at 4 oclock that is TDC compression stroke, if it is at 11 oclock that is TDC exhaust stroke.......

But I had the entire cover and gear and oil filler neck and ip and lines out. So even if the dowel is at 4 oclock it may be off. Is there a way to make sure im at tdc compression other than that dowel?
Me and him are in the same boat. Im gunna be pulling the GP again and checking for pressure and then checking the dowel for the 4 o clock position.I thinki did it right the last time but still no start. very frustrating!

Check and make sure ur getting fuel to the injectors. Ur fuel shut may not be working or kicking on the pump. Just swapped the engine in my papaws chevy 6.5. Checked every connection three times ended up being a bad ground wire not make good connection. Replaced the end and it fired right up. The ground was effecting the computer.
You might check to see if you are getting voltage at the fuel shut off solenoid first.
If you are, turn the key to on, and unplug the fuel shut off, then touch the wire to the terminal and listen very closely.
You should be able to hear a click as the fuel shut off solenoid opens and closes.
If you pass all of those, IP timing is the next thing to check.
