The dash ie odometer, and check engine light comes on. It cranks fast, and it will pop off like its about to start and then it goes back to cranking

Welcome to the site. You're going to need to provide a whole lot more info for us to even take a stab at this, but read the link above, re-post and we'll start picking this one apart.

 

Need more info. What mods are done to it? when was the last time the fuel filters were changed? How old are your batteries? Read the sticky about the help for newbies and posting threads. Need more info to help.

ahhh mdub you beat me too it...

 

This was suppose to be in front of last one, I have a 05 F250 6.0 turbo, i have recently swapped the engine b/c the egr cooler went bad and dumped fluids in places they weren't suppose to go (upgraded the egr cooler). I have had it back for a month now. It cranks but will not start, I have drained the water seperator, purged the fuel lines (disconnect from the head and turned over three times), replaced the fuel filters, pulled and cleaned the EGR valve, charged batteries both will hold a charge, cleaned the battery terminals. I did notice oil around the oil filter housing. I am going to check the FICM as soon as i can get my hands on a volt meter. but any ideas would be greatly appreciated

no mods all stock batteries aren't but a year old give or take a month. fixing to check the ficm, will post the readings

 

have you load tested the batteries?

 

went and bought a charger/tester last night they are holding a charge

i see some oil around the oil filter housing. could it be the hpop not getting enough oil pressure thats not letting it start. im by no means a diesel mechanic i jus did alot of research on this and just asking

---AutoMerged DoublePost---

it stopped turning over and is clicking now my battery tester/charger says they are charged and the volt meter says driver side battery is at 10.90 and the passenger battery is at 11.90 but its like they don't have enough juice to turn the truck over

 

your batteries probably have the voltage but not the amperage (the capacity to crank it). get some new batteries.

if you can get a scanner with datastream, check and see what your hpop is putting out for psi.

any codes?

---AutoMerged DoublePost---

also can you see if anything has come unplugged? IPR? ICP?

 

Were you getting any smoke out the tail pipe when you were turning it over?

Your oil leak is on the low pressure side, so as long as it's pretty small it really shouldn't effect the HPOP. Though, I'm not ruling the HPOP out, we just need more info.

You don't really need to bleed the air out of the fuel system like on other engines, this will work itself out. It may take a while to bleed the high pressure oil though, but usually 3 or 4 times of 20 second cranking should get it fired, worst case.

I'll bet you're not getting smoke out the tail pipe, and I'll bet it's some electrical connection causing it. Especially since you just did an engine swap.

What year truck do you have and what year motor was used? How many miles on the new motor, and what was the life of the motor before you got it, if you know that?

 

I agree, the batteries are clearly drained, they really need to be load tested, not just read with a multi-meter.

To check HPOP pressure, he needs to read ICP actual and ICP desired and compare the two. Desired is what the truck wants, actual is what the HPOP is doing. I'd also check IPR duty cycle along with those two to really see what's going on. The IPR is what commands the ICP. If IPR duty cycle is up near 75% or 85% you either have a stuck IPR or a high pressure oil leak somewhere.

If ICP was unplugged, the truck would start still.

 

The oil around the filter housing could be form the O ring on the filter cap. Check the O ring and replace as necessary but be sure to lube the new O ring so it doesn’t bind while tightening. As for the tester/charger it is only a way to test how many volts and charge the battery. It is not the way to load test the batteries. The batteries need to be load tested. Any auto parts store can do this. Sounds like they both need to be replaced.
