Bastardized lb7

[crazybrowner]

Hey. I have a problem lb7. Truck came for me for tuning after a hack put a bunch of used parts on reused every seal and had stuff bent and twisted. Even had a broken wire fixed with a coder pin jammed in the main engine harness connector lol. It has S366, air dog lift pump, stage three cp3 (12mm) w/lbz frp (stage 3 floor it diesel cp3) headstuds/gaskets, built trans. Truck won't start on its own. https://uploads.tapatalk-cdn.com/20170709/8a54650de1cb282de607ae6a3f708309.jpghttps://uploads.tapatalk-cdn.com/20170709/886a720e5326eec4ef439e8a6e59b47a.jpg off idle it builds proper rail pressure still doesn't run right with ppei max effort tuning for pump and turbo. And second pic is key on engine off. Injectors have 30k on them supposedly.

Does this truck have an LBZ regulator in it?

[crazybrowner]

The stroker pump had a lbz regulator on it yes. We tried the stock one on it and no change.

how many RPMs on cranking?

have you looked over all of the fuel system, filter housing for leaks for air getting in? does it have a lift pump?

can you get us the screenshot of it idling?

Not sure on rpm rolling. Rolls over fast. Has a air dog and I've bypassed the filter housing and triple checked all the fuel lines

If it's rolling over really fast trying to start it wouldnt that indicate loss of compression? Maybe not complete loss but one or so cylinders?

So after doing injectors it starts mint has agressive diesel knock. After screwing with it desired rail pressure was double unhooked the air dog and it
