Motors in, working bugs out. Need direction
Been tinkering on my lly all day. Had a fuel leak pop up on injector 3 at around 55psi of boost on a tow tune. It's spraying outta the injector bore I believe. Shut it down before any harm could be done. Wonder what would be causing it to spray out? Coming directing around the retainer on it and sprays like a mofo.


Also on boost. I had rob Coddens build my dsp setup for my twins, injectors and dual fuelers. Cruising around in the subdivision it builds no boost. You have to roll into it a bit before it'll start spooling. Looked thru the tune and it should be cruising with closed vanes, but they seem to be wide open. Doesn't have any exhaust leaks around the block on manifolds or uppipes, so not sure why it's doing that. Snap on scanner and Efi it checks out fine. Any ideas or directions to go?

Could be a copper washer not seated...... defective or there is debris under it or between it and the injector and not allowing the injector to seat all the way.

Possibly. It idled for around 4hrs in the drive and never dripped the first drop. Took it out and got it spooling some and then it was a high pressure spray. May have cracked the body but I have no clue why?

There is a check ball type deal on the body of the injector. If its pissing out of there your injector is junk.

How u go about seeing if it is? When in the vc u can't see the bearing on the lly bodies

Unplug your regulator and be careful

Unplug my regulator? I have dual pumps. And maybe I'm not understanding u correctly but what's that gonna tell me? Need a flow machine to see where it's spraying out. The injectors are new they was reworked and fitted with new nozzles, then balanced and flow tested, and drip tested.

If you unplug one of your regs, it will max out pressure so maybe you can see the leak better.

I'm a bigger fan of commanding max pressure with EFI. It is usually easier (maybe not with dual pumps, where one regulator is right out in the open), and the computer still has control, so its not straining the pump or hitting the relief valve.

I dnt need to command more fuel, hell at normal idle it sprays enough to hit underside of the hood. It's cant see much when looking in the wheel well. Spraying out strong around the injector retainer. Which I'm assuming the body cracked, no clue why still, can't really see it not being seated, heads are brand new.

Does it leak out of the top at the return line? That's what it sounds like to me

 

[05Monsterdmax]

I'll fool with it tomarrow if I get time. Believe it's cracked the body though, coming out from around the retainer and spraying up in the air. Just doesn't make a lot of sense why it done it though.

Any ideas on the boost? Boost isn't coming in till half throttle, more so noticeable woth the big charger. Almost like a leak on cold side but dnt know how. Any way of testing for a leak in the y bridge or intake runners? Sounds like it did when I blew a boot on the cold side with my old cheetah setup, meaning hardly no boost and vanes wide open at any speed. I have the 3" y bridge and it's a mother to get in and out or I'd just simply pull it
