Picked the truck up at the dealer saturday.Running good again.I learned a lot working on this myself.expensive lesson.I wrench for a living but i was just guessing at which injector was bad,I should have known better.Thanks again for the help.:)

ok,thank you for your help!

Dealer called said.#4 is a dead injecter,Thats all they can find,now this thing will run for a couple mins and then quit.would 1 dead injector do this.he says electrically it checks out.I,m a bit skeptical. What do you think?

What ive done so far.replaced 2 injectors on right bank,replaced orings on right bank,replaced 4 oring sets on left bank.this was before i discovered the extra oring and plastic filter piece in top filter housing. i'm basically back at square one. still getting air bubbles in fuel cup so maybe i...

top filter,theres a plastic piece in there that engages the cap.went out to move it ficm volts went down to 44 stayed 45-46 till alt kicked in.its about 20 degrees out.

I put a scanguage 2 on it,ficm voltage stays 47-48 even though i did see 44.5 for a second,ipr,800-900 icp 25-31% none of this changes when it starts acting up.Its going to dealer tomorrow to have diagnosed.One thing I did find was part of the old fuel filter and oring still in housing. It would...

I took the other side apart.3 injectors had sucked orings.so i replaced with 4 oring kits.didnt change a thing.still runs 5 minutes then starts missing ,shaking and ratteling.ive got 50-52 psi fuel pressure which is a bit low.i dont know what else to do.

Thank you for your help, i put it back together and i'll haul it off to the dealer to have it checked out. see what they come up with.

So i guess i screwed up by taking it apart before i knew which injectors were bad,I dont really have the cash to replace all 4 on that bank.I read on the internet( so it must be true right ) that i could vacuum test.put a hose on the end of the infector and see if it holds vac.True or false. to...

no, nothing looking like soot.maybe 1 with a little burnt oil.2 injectors look reletively new,they say reman 10411 on them.

pulled injectors today expecting to find a bad crush washer,nothing obvious..so?

So heres what i did today,i rechecked the fuel bowl for bubbles and sure enough i had bubbles .so i unhooked pass side fuel line at cyl head and did test again, no bubbles.so does this mean bad injecter or an oring leaking?

Dummy plug o-ring would be located where? thank you

my truck started running a little rough on the way home from work,43 mile drive.by the time i got home ,it was barely running and quit would not restart.once it cooled off it starts right up runs good for maybe 5 minutes then starts dropping cyls. cool off and repeat.I changed fuel...
