I got an 05 178xxx ran home last night 480 miles truck was running when I parked it got in it this morning to got to work and it won't puff smoke turns over but won't even try to fire sounds like no fuel I suspect the injection pump but I don't know of a way to test it I have a fass system that's about 3 months old already filled the filters with power service and tried to start and still wouldn't thanks in advance

 

Where are you? Did you get fuel from a warm state and shut down in a cold state? If it's gelled fuel it takes a LONG time to clear, and a lot of cranking before you'll get anything that resembles a running engine.
Any codes? It's rare (but not impossible) for an IP to fail suddenly, and with that few miles.

 

I'm in arizona cold here 40 but got fuel in colorado I have got the fuel drained from the filter and the lines it was treated not real heavy but wasn't cloudy at all it has always took alittle cranking to get this truck to start lately it seems like it takes a little longer

 

Still can't get it to fire got fuel everywhere it needs to be just won't start I have fuel leaking at the pump off one of the fittings that look like it has a bb in it almost convinced its the pump anybody know a way to check it?

 

Most likely excessive return flow from injector. Try capping the injector at the rail first. I start with # 3 only because you can cap it without taking the intake off first. #3,#4,#5, #6. You will need a capping tool. Be aware injection pump is capable of injecting high pressure diesel fuel into your skin at 25,000PSI which would be fatal. Never work on a high pressure system with the engine running. Tighten down all the HPC nuts to 37ftlbs also when the injector fuel line is removed.

This is procedure to check the CP3 pump.


HIGH PRESSURE FUEL PUMP PERFORMANCE TEST

6. 5. Disconnect the FCA harness
7. 6. Disconnect high pressure fuel line from fuel rail and route the high pressure fuel line into a graduated cylinder.
8. 7. Crank the engine until fuel exits this line. This will not be high pressure fuel.
9. 8. Crank the engine for three (3) 10 second intervals (Note: This will give you 30 total seconds of flow time. These are broken into 3 separate intervals to prevent damage to the starter). Fuel flow specification s based on engine cranking speed. If you do not collect the stated amount of fuel in 30 seconds, replace the pump:
10. Minimum fuel pump flow at 150 rpm cranking speed is 70mL
11. Minimum fuel pump flow at 200 rpm cranking speed is 90mL
12. If the engine is a no start do the following:
13. 1. Remove fuel pump to railhigh pressure fuel line.
14. 2. Inspect the fuel pump outlet port for rust, debris, or other signs of contamination.
15. 3. Replace pump if any contamination is found. Check for source of water in fuel or debris in fuel to prevent future complaints. If no contamination is found continue to step 4.
16. 4. Disconnect the Fuel Control Actuator (FCA).
17. 5. Disconnect the high pressure fuel line from the fuel rail and route the high pressure fuel line to a graduated cylinder.
18. 6. Crank the engine until fuel exits this line. This will not be high pressure fuel.
19. 7. Crank the engine for three (3) 10 seconds intervals.


NOTE: This will give you 30 total seconds of flow time. These are broken into 3 separate intervals to prevent damage to the starter.
20. Fuel flow specification's based on engine cranking speed. If you do not collect the stated amount of fuel in 30 seconds, replace the pump:
21.
22.
23. Minimum fuel pump flow at 150 rpm cranking speed is 70mL
24. Minimum fuel pump flow at 200 rpm cranking speed is 90mL

 

Thanks big iron I will check that out I don't know if I have anything in ml around

 

Well measured the flow off the pump I'm getting just shy of 200ml on 30 seconds of cranking 3 10 second intervals that's about 150 rpms

 

Then I would say the CP3 is OK most likey injector leakage causing no start. Try capping injectors next, if you can monitor fuel pressure at the rail when cranking over engine should have 4,000 to 5,000 psi. If you have a programmer what's the rail pressure when cranking?

 

I don't have a programmer to check rail pressure I sure nneed one now thinking about a banks iq would a smarty read it? I've had this truck for a long time and the last few months it has taken a little longer cranking to get it to fire don't know maybe not related I keep checking the oil just had it changed before I left I can't smell diesel in it and the levels not getting higher you can't even smell diesel in the exhaust I'm gonna have to call the shop this morning and have them hook it up to a scanner not being able to tell what's wrong is freaking me out a little

 

Got the truck fired up drained the rail overnight and plugged it in forwhat ever reason it started this morning no codes on it still after all of this crazy stuff. Sent it off to the shop while it was running.
Thanks for all the help

 

Lets us know what they find, I would bet money #3 injector and injector tubes leaking.

 

Subscribe! I really want to know what you find out on this one! Please. ")

 

I will keep you guys posted the truck is in the shop right now I had to go back to work I should hear in the next couple of days , thanks for the help

 

Well I got the verdict from the shop injectors were wore smooth out I kinda had an idea that's what it was. Couldn't get enough pressure while cranking to start all the fuel was going straight thru ordered a new set from industrial should be running by the end of the week. I got 177xxx miles on factory injectors with napa fuel filters no fuel additives lots of fuel out of transfer tanks and plenty of idle time I think 3000+ hours on truck I guess I got my money out of them but I don't think they are even good for cores thanks for the help
