Is that ben buddy?
Not sure, i just remember he did someone else wrong on here and i do remember him hurting the motor in his lbz and then he parted it out and he sold 2 or 3 motors just asking.Others have sold motors on here since then just taking a stab at it.


I have been victim of injectors sitting for a long period of time,i bought a 2000 mile 01 lb7 engine that has sat for 9 years and i thought dam only 2000 limes on these injectors i had it made. Not so,had 2 bad injectors the rear 1s on both sides was only making 300 psi.I did find them by pulling the inj fuses and glow plugas as you said and had someone on each side and cranked it over the hung injectors sprayed out the glow plug holes.

with fpr unplugged it would go wide open if the barrell wasn't stuck shut.
What if the fpr is totally stuck shut?
the lmm or lbz want about 3k rail before injectors will fire


no kiddin, its a simple test to verify the ecm and/or wiring is sending too much power to close the fpr and completely cutting down fuel pressure. If rail doesnt raise, you atleast elimiated a possible fault.




What is the issue?...I have done that before, and its a wothy suggestion. Imo

Thats what im sayin :confused:
