I bought this thing a few weeks ago, not running. It had died and gotten a new IP but wouldn't start. So, it has a new IP, the lift pump is working, glow plugs are working, power to the pmd is good, pmd has been relocated. It's getting fuel and cranking strong, just won't quite go... I found a website with instructions to test the pmd by measuring AC voltage off the B and F connectors on the PMD harness, I forget what the voltage was, but it was in the range they said was good. It cranks good, with black smoke, so I know its burning fuel. Any ideas? Thanks in advance!

 

did you check the voltage going to inj pump

 

I'm not really sure what you're talking about... I checked the signal from the pmd to the pump, as well as the optical sensor in the pump. Is there another electrical function on the pump?

 

There is a shut off solenoid on the pump but if you are getting fuel to the injectors it should be fine. What kind of compression does it have? Is the pump timed right to the engine?

 

I don't know if the pump is timed to the engine or not, the previous owner installed it. Compression seems to be good, but my guage doesn't go high enough, so I need to pick up a new one... How can you know if it's timed correctly or not?

 

if there is smoke coming out than the electronics are fine. pump is not timed to the truck. to time it your going to need a scan tool like a tech2 or car code or autoengunity.

Checking/Adjust injection Timing
This procedure should be used after an injection pump installation or when injection timing needs to be checked or adjusted. A scan tool must be used to check or adjust injection timing. A static timing mark can be used as a reference. If a static timing mark is not present on the injection pump mounting flange, one can be scribed to further assist in how far the injection pump needs to be rotated.

NOTE: There will be no change in engine performance or vehicle driveability if the injection timing is advanced during the Time Set procedure. The injection timing must be sot to the Injection Timing Specifications. If the injection timing is not set correctly, a possible DTC P0216 may set (see DTC P0216, the Conditions for setting the DTC). Refer to Diagnostic Tables . See: Computers and Control Systems\Testing and Inspection



1.Start the engine.
2.Allow the engine to idle at the normal operating temperature.
3.Install the scan tool.
4.Use the scan tool in order to activate the Time Set (if the Time Set has been activated correctly, Des. Inj. Time on the scan tool will read 0.0 degree).
NOTE: The Act. Inj. Time value on the scan tool will fluctuate. The Average reading should be 3.5 degrees .



5.The Act. Inj. Time (scan tool display) should be approximately 3.5 degrees. If not, continue to step 6.
NOTE: If the engine stalls during the Time Set activation, slightly (1 mm equals 2 degrees) rotate the injection pump toward the driver side of the vehicle, tighten the flange nuts and repeat the Time Set.



6.If the injection timing needs to be adjusted, continue. If not, this indicates that the adjustment is complete.
7.With the engine OFF, use the J 41711 in order to loosen the injection pump flange nuts.
8.Use J 29872 in order to slightly rotate the injection pump.
9.Set the Act. Inj. Time to 3.5 degrees .
NOTE: It is normal for Act. Inj. Time value on the scan tool to fluctuate. The average fluctuation of the Act. Inj. Time should be
3.5 degrees .



10.Continue to repeat until the average fluctuation of the Act. Inj. time is 3.5 degrees .
•If the Act. Inj. Time is above 3.5 degrees, SLIGHTLY (1 mm equals 2 degrees) ROTATE THE INJECTION PUMP TOWARDS THE PASSENGER SIDE OF THE VEHICLE.
•If the Act. Inj. time is below 3.5 degrees, SLIGHTLY (1 mm equals 2 degrees) ROTATE THE INJECTION PUMP TOWARD THE DRIVER SIDE OF VEHICLE.

 

Project update:
Been meaning to get on here for forever, but college seems to be stealing all my time. So, a compression test revealed that compression is all over the map. I pulled the heads, and found melted pistons, then pulled and stripped the block, and found out my whole engine is destroyed beyond the capacity of my machine shop to repair. So, Dieseldepot 6.2 turbo, here I come. Also planning on +40 hp injectors, and full up instrumentation, and maybe a fuel miser chip. We'll see.

 

get some genuine bosch injectors not that chinese junk ss diesel sells.
