no start after 366 spring install???

[kylehawk10]

I pulled the ip apart and installed the 366 spring yesterday. Fairly straight forward... so i thought. While I was in there, i gave the starwheel a 2 turns down and the smoke screw as well. put everything back together and put the throttle linkage back to its factory index. When bleeding the injectors i noticed the fuel was more of a dribble out instead of a sharp squirt, didnt seem like much pressure. plugged the fss back in and it spun over a few times and fired off. It idled for less than 10 second and dies. Has not started since. i've tried bleeding injectors several times with no luck. I pulled the plunger on the fss.. no luck. i swaped the lift pump from a runnig truck.. no luck. Someone has already messed with the full power screw before me ownig the truck and most likey the star wheel and smoke screw.

After all this.... the truck will spin over and hit on one cylinder only. While spinning over it smokes quite a bit. defiinatetly getting fuel to the injectors, maybe just insufficient pressure????? any ideas??

You didn't need to bleed the injectors for just the 366 spring swap.

Have you tried holding half throttle while trying to start it?

Check your manual shutoff isn't stuck in the off position.

Most likely a throttle indexing problem, this is the case 90% of the time after a spring swap.

Biltit,
I have tried holding the throttle in every position while cranking. As the enging turns it hits on one cylinder and smokes on all the others.

and the manual kill is in the run position. easily returns back when pulled

I had the same problem with a new IP, run your power screw in a bit. Mine would spit and sputter and carry on until I cranked it in until almost all the way. Fired right up.

[kylehawk10]

Cranked it in until it bottomed out, still no start. However, I have 5 threads sticking out behind the jam nut. Should it go further befor bottoming out? I'm wondering if I need to pull it all the way out and chase the threads..

[CumminsPower59]

Its bottomed out. Don't force it, it'll tear the o-ring that seals it. Five or so threads is about normal. I'd go back through the supply system and make sure that all the air is bled out, took me a while to get all the air out of the fuel system on my 91...

[kylehawk10]

New filter and it fills with the hand prime no problem
Bled all the air on the supply line into the ip until all bubbles were gone (hand pump)
Cranked and bled injectors one at a time with a substantial amount of fuel coming out. Not much pressure but fuel running out everywhere none the less.
While bleeding the injectors it still smokes on all cylinders and hits on the one.
Hand pull the manual fuel shut off and smoke stops.. Let it go and same story.. Sputtering and smoking

I'm very familiar with diesel fuel system as all of our equipment are John deer and cummins diesels. If this system is just air locked or sucking air from somewhere it's got me beat!! I've bled this thing so many times!!

Is there any way it could have jumped timing wise?? Should I pull off the cover and look for anything in particular? The ip was never taken off the engine and the truck ran fine before tweaking it.

[skilletky]

if yer like me, you pulled the pump away from the head (retarded timing) to get to the pump top bolts, and didnt set it back to where it was when you were done. it will smoke and smoke and hit on a cyl but wont start. i felt real dumb when i figured it out

[DMan1198]

If it were just an air in fuel problem it'd start and idle fine but go to rev in and it'll sputter and belch white smoke. That's what my truck does anyway

[DodgeFreak]

even with the pump off the engine it won't jump time just sitting there. I'm not sure it would just time if you tried to make it. When you pulled the top did you pull the fuel screw out?? or did you try to move the lever forward as you dropped the top back on? And like skilletky said did you rotate the pump?

[kylehawk10]

I backed the screw all the way out so that it was nearly flush with the inside of the pump casing.

[kylehawk10]

I never rotated the pump

[DodgeFreak]

Did you get the tophat\spring together right?? I'd pull the top back off and double check it. I'm wondering if the spring didn't come loose maybe.

I had one heck of a time getting mine running after the 366 spring install! Thought I had the throttle indexed right but I didn't. 2 friends had the same problem. Had to turn the throttle levers back just a bit farther while pressing down till they 'clicked' down into place on the shaft, to re-index.

Been a few years and maybe it was when I replaced the head gasket, not the spring install, but had to spend a lot of time bleeding injectors. Like yours they would bleed fuel but not at high pressure. As I recall I finally cracked 2 injectors and left 2 tight and cranked it, then it would bleed and try to start. Then tighten those 2 loose ones and loosen the 2 tight ones, repeat. Eventually it would run on all 4, reluctantly. Been running fine ever since.
