Isx wont start

[Toddmsc]

I'm going to go mess with it more now.

Unilever's
1 insite I've already ordered still waiting for it. I've gone too damn long without it and now its frustrating.

2 she runs fine off the sniff. Dies once you stop.
It ran fine when I brought to that shop making me believe put together with a leak or pump failure from the coolant running through it....then them trying to start it air bound was probably its last straw.

3 lift pump is actually really strong and very constant certainly doesnt have lack of flow in that department.

4 going to check rail relief today.

5 also today gonna pull head bc I have new one on the way in am. Truck has almost 900k on it and no records that I see it was ever changed.

6 I wanted to do this. Unfortunately dont have any old lines to weld and make plugs to do this. Any other suggestions on how to do it?

7 have to find someone with a gauge..

Going to check that relief today.
I was unaware and havent heard about the feed tubes being a one time use deal. Not saying I'm right or maybe just lucky but I've never replaced them. Usually take them out, mark it and the injector and always put back in respective holes with new o rings and never had an issue. Unless of course shop paid no mind of attention to this and mixed them up.

I've even jumped the metering rail pressure sensor to make ECM think it had the pressure and not even the slightest chance of it starting.

If you crack high pressure line at pump and crank you can def see pressure build a slight bit but no where near what itd need to start.

I've done many of these 2350s and never had a problem yet. I've done heads, rebuilds, cam jobs, injectors. Always trouble free and ran great via quickserve specs for exact serial.

Problem is when you look up fuel pressure trouble shooting they run you over the hill before you can actually do it their way. 200 bucks for the orfaced test line, then they want you to get beakers and measure for cranking. Quite a few tests they want you to perform in insite. They make it virtually impossible to do yourself. But at the same time you know as well as I do these jokes of mechanics at dealer will waste your time bc they are inexperienced and wont do it properly ether...so theres always that.

To me I think the pump head is absolutely throwing parts at it. But my theory is truck has 900k. No record of it ever being done or updated. So I dont think itll hurt anything to replace it. Its security at this point.

Cannot wait for insite tho, good god not having it is a total pain in the arse.
