So i had a problem a while back truck shut down 4 cyl 1,4,6&7 after inj 1 shorted i replaced the passenger side injectors 1,3,5&7 since i was in there, after getting it back together it ran fine for a week and then inj. #6 shorted, and instead of replacing the whole injector i was told by SirRoland i could replace just the injector solenoids and would work (the same thing happened to his truck) so i replaced just the solenoids on the driver side and now im trying to start it and it wont start, (i pumped the shit outta the primer and all that, i know it takes a bit for all the air to get out of the system for it to start after having the quick disconnect fuel lines on the driver side and the hp lines all off so i made sure all that was bled) and new fuel filter too than after still no start and reprimingI waited for the glow plugs to go off before shooting some starting fluid into the turbo horn and it starts and runs for 10- 30 seconds and shuts off. But when it would acually run it would also spew fuel out the exhaust, making a huge messs not only on my property but my neighbors and they got pretty pissed (it has a stack big MESSY mistake shot fuel everywhere ), its not currently running any codes except the p0380 or whatever for the glow plugs and it was 60 degrees out today so the glow plugs shouldn't be a prob, need help please truck has been down ten months really need to fig this out.

You see how easy it is to turn over by hand? That sounds like a crazy if it made a HUGE mess! You might want to pull the glowplug out and see how much fuel it really has in the cylinder before you go and hydrolock the engine. Maybe it just was water?!

There is a very small ball bearing under the solenoid, it fell out of its seat and the injector is now stuck on. It isn't worth the effort trying to find and fix it on an lb7. You are better off replacing the injector at this point. Do yourself a favor and take out the glow plug on that cylinder and turn the engine over by hand before starting it again.

Bmc1025 i agree it seems like one injector is hung open but i made sure nothing moved or fell out while i was installing the solenoids, and was very careful with the posts although i felt like i might have overtightened one maybe it broke internally but doesnt appear broke, is there a certain procedure on installing the solenoids? Seemed pretty simple the old ones unscrewed and i put the new ones on the same position the originals were otherwise the injector harness wires dont line up, thanks for the replies
