How much cranking after injector swap?

I replaced Injectors 5 and 6 on an early 6.0

2003 6.0
Buttoned everything back up cycled the key a couple of times and tried to crank in burst of 20-25 seconds.
after probably 8 or 9 burst... still no start?

Is that common?
I show oil pressure on the dash, I smell no diesel.

The only thing that "Kinda Bothers" me is I had to replace a plug and o-ring, i replaced with a matching "bolt"and o ring.. thats the only ödd"thing of the rebuild.

Any thoughts....... Im really bothered!!!!!!!

What plug and oring on a early engine did you replace? The early ones are usally easyer to start then the later. Should have started with those cycles. Can you monitor ICP and IPR while crasnking?

Earlies have much less volume in the oil rails, which plug did you replace? That 4mm one on top of the oil rail?

Yes the small one on top, it only had 2 a large one and a small one... also a braided line from the top of the rocker box to the rail...

I do not have a way to monitor the ICP or IPR...

Why did you replace the plug? I didnt know they were servicable. With out readings it will be hard but I would guess there might be a HPO leak.

Twisted off by a curious newbie.
Also thinking hop leak.
I just noticed for the first time just now I smelt diesel fuel out the exhaust. ...am I getting close?
it didn't have the sensor in the valve cover as I thought it would.. it was a simple install. or so I thought...

So, here's a pic a took when it was apart. the plug is the small one on top.
like i said i began to smell diesel fuel when I stopped last night, am i getting close?

Can i pull the valve covers off and crank it to find a possible HPO leak?

See pic attached...[IMG][/IMG]

Re: How much cranking after injector swap?

Yah...I would start with pulling the covers and seeing if you can see a leak...make suee the high pressure lines are cliped in. I know it seems easy but I just did that to mine.

i unscrewed the line from the rail, instead of uncliping it... was that a bad move?
