99 F250 Starting Hard Getting Worse
 

At 240,000 miles Recently I have noticed that my Powerstroke has been starting to start hard. It started as just a few seconds. I would wts light to go out then crank it - no start stopped let cycle agian and seem to fire right up. No few days later same process but not starting till after several long cranks - just starting doing this. Also blows white smoke on start not sure what this means. Fumes are really strong out of the exhaust.

What I Tested: A few month's ago dealer replaced CPS under recall, Replaced glow plugs none of old ones were bad. Checked GPR with multi meter 12+ volts for I think 2 min. Checked the HPOP full of oil in resivoir, Pumping fuel out of filter fine.

Please help leaving Wisconsin heading to North Dakota and don't want to be stranded, Thanks All:madd:

Are you having to add a oil very often? Since the high pressure oil is 1000 psi at cruise and the fuel pressure is 60 bad o-rings on the injectors could let oil into the injector system. It will run on the oil but it is harder to light oil in a cold engine.

now you do mention I did a service on the truck about 3 weeks ago, and just checked the oil and it was almost 2.5 3 quarts low couldn't understand it. I did have the injector orings replaced about 3000 mile ago could they be bad already again. should I put a fuel pressure gauge on it? Is this maybe why it is smoking white at start?

An o-ring might have been damaged while installing. I don't think they would go bad that quickly but stranger things have happened. It could definitely cause the smoke until it warms up because oil doesn't burn easily cold. The fuel pressure gauge wouldn't hurt but might not tell you much. A high pressure gauge would likely be more useful. I used a gauge off a dive tank regulator to test our 01 F250.

Ford has a scan tool that will show if each cylinder pass a test cycle. I had a local shop hook my truck up to this scan tool and showed my IPR was way up before it would fire up and it showed #8 cylinder didn't pass the test. Sure as poo when I pulled the #8 injector the o ring was munched.

Thanks guys I will talk to the dealer.

OK here is what I got fo update. I come to conclusion that dealer don't know ^%$%^. Checked for power at all the glow plugs and ok. Used a infered temp on each cylinder and all are consistent. This is what worries me. It seems to be blowing consistant white smoke now and went thru almost 8 quarts of oil in a week. I just added 8 quarts of oil to it. Checked the intercooler hoses and did not find a significant amount of oil so?? Now I don't know what direction to go, Should I go thru and replace the Orings again? Does anyone think it is Engine rings. I hope not but the truck does have a lot of miles 240000 to be exact.

If it's white smoke, you got some crap injectors. I would also look at replacing the HPOP.

updates??

Sorry, Took truck into the Hucksdorf in Franklin WI waiting to hear back. Sounds like injectors. In the past two weeks I have went thru almost three gallons of oil.
