I noticed one day the oil pressure gauge took 4 seconds before showing me high pressure on the cluster while the engine was running. I know before as soon as I crank the engine the oil pressure was normal. The truck ran normal. A little while after that, it started shaking and when I stopped at a light, it died on me. I start the truck again but I noticed when I let my foot off the accelerator, the engine wanted to die. I had to drive holding the brake and gas peddle both to keep it from dying. I parked until the next day and when I tried to crank it nothing happened. Gave it a shot of ether, nothing happened. It doesn't even try to crank. I replaced the oil, oil filter and both fuel filters. Can anyone offer me any solutions that don't involve a dealer because I'm in Mexico for a few months with my family.

 

If it doesnt crank at all...

Battery, starter, cables, solenoid... start there.

 

It spins over, but doesn't start, not even with ether. Sorry if I was confusing. I've checked all of the things you stated above.

 

NO start check list in tech folder.

A) Verify battery fully charged.

B) Verify cable / Alternator

C) Verify fuel supply via small filter (remove and see if it is pumping), and then, proper pressure if you have gauge and test port adapter.

C) Verify FICM voltage

 

Just an FWI don't use ether on any new diesel. It is really bad for the motor. There is a no start thread in the tech folder. Start there.

 

Remove the oil filter from the housing. Using the single yellow with light blue stripe coloured wire on the passenger side engine compartment, directly above the vacuum pump, disconnect the two halves and jump the male end of the connector to the passenger side battery postive terminal to spin the engine over while you observe inside the oil filter housing. Does engine oil rise inside the housing, and if so, how quickly?

 

Thanks for the quick replies. I'll go through everything that you all stated, I'll check back.

 

@m-chan68....I followed the steps you gave me, and no the oil is not rising in the housing and now I have no oil pressure at all. Is it possible the ipr is blocking the oil pressure from rising? Do you have any advice on what to try now? This is something that I have to work on when I have the extra time. That's why the long intervals. Thanks in advance.

 

your going to need to remove the low pressure oil pump and see what of anything has gone threw it. if / when you remove the pump gears try and get very clear pics of both gears and cover post them up here and myself or one of the other techs may be able to tell you were to go from there.

 

I'm posting the pictures but they're not very clear. However, the gears are very scratched and jagged on the ends. The cover of the housing is also scratched with grooves. Also, no oil was going through.

Hope I did that right...

 

I agree, those gears look pretty scored up. Were you able to retrieve any foreign debris in all of this? Either an injector has blown its top or roller lifter(s) needle bearing(s) have failed. Both WILL pass through the oil pickup screen. How does the front cover surface look? If you can't retrieve any missing pieces, perhaps your next step is to remove the oil pan for further inspection. Believe it or not, oil pan removal on a 6.0L is not very difficult at all (unless it's equipped with a manual transmission). Simply remove the engine mount to frame fasteners. Jack the engine up about a 1/2". Remove all 8mm bolts that secure the lower oil pan. Slide the pan rearward once removed, and remove the two 8mm bolts that secure the oil pickup to the upper oil pan to give you the clearance needed to complete the removal process. Good luck and post up pics of what you observe.

 

Thanks for your quick reply. Yes I found debris in the oil and the oil filter as well. I already replaced the oil & filter. The front cover surface was scratched more than the housing. My question now is do you think I need to replace just the oil pump gears, or the housing or both. The bad thing is I'm in Mexico and it's very difficult to get these parts over here.

 

if the cover is damaged then it should be replaced. if oyu dont find the object that passed threw the gears then you may have more issue further down the road. particals have been knowen to be stuck in the pick up tube, pan, front cover and oil cooler.

 

Everything above has been replaced..(gears...etc..) I replaced the low pressure oil pump, and I can see my gauge registers oil right away. Before that wasn't the case. The strange thing is the engine still won't crank even with ether. I don't know what else to try to make it start. I've already spent the motor for a half a minute about 10 times, once or twice with ether. I also have two new batteries. I've already checked the fuel pressure again and it's good. I have new fuel and oil filters with new oil of course. I know for sure any motor should start with ether, so I don't understand. By the way, it's a NO START, cranks but won't start now. Sorry. I don't have cooling on the engine right now because I haven't put the radiator or the clutch fan back on yet. Do you think that could be a possible reason for a no start?
