    Need help, LB7 no start

    No, they all look a bit off, but I'm going to start with 2 obviously, and 5 at the same time, hoping that the rest will even out from trying to overcome the bad injectors in 5 and 2....we'll see.

    Need help, LB7 no start

    Looked in my coolant tank this morning, it's low again, so I'm using coolant. I guess I will just pull all of the injectors on that bank, pull the cups, seal them up with new O-rings and Loctite, put it all back together and hope for the best. Damn I'm getting tired of working on this thing....

    Thats what I lean toward, but have read about bad cup seals and what not too. Not sure if bad seals will make it smoke and smell like its pouring fuel out the pipe. Also have a cyl misfire #2 DTC P0302.

    So, now after a few around town trips, truck is knocking, coming from the left bank. Doesn't matter cold or hot, getting a bit of smoke now when I first start to pull away from a stop, and a lot when it downshifts and speeds up on the freeway. Don't notice any knock at higher rpm, only about...

    Well, figured this damn thing out finally. One stupid injector was returning all of the rail pressure back to the tank. Started capping off one injector at a time until the truck started, low and behold, cap off #4 and it fired right up! Happy and pissed all at the same time. Thanks for all...

    So....update. I got brand new injector feed lines from Pensacola...installed, still same issue. Primed for about an hour last night, no start. Same same same. So, getting caps made from the old lines, going to try to isolate each bank and try that. Found a guy with EFI Live, hoping he can...

    I do have another question....the high pressure fuel lines. At the injector, the corrosion. Each one of them has what I think is a good clean surface for the metal to metal seal, but maybe one of them is leaking? I don't seem to be making oil, can't smell it on the dipstick, but....is it...

    Cool, thank you. I pulled the injectors out, sending them back for testing. Saw nothing wrong along the way. Once they get back, install, try again, then going to try to get the actual pressure, plan on capping off one bank and try it, then the other bank, one injector at a time....see...

    I take it that desired is what the computor is telling the truck to achieve, actual being what I am actually getting. I'll have to find a way to pull that data.....

    Need help, LB7 no start

    Ok, so this would be to rule out one bank dumping all of the rail pressure to the return? So, the difference between actual and desired rail pressure is what?

    Need help, LB7 no start

    I have heard that referanced a few times in other places...not sure how to check that, I don't have a tech 2 or any kind of scan tool other than a simple OBDII code reader to pull it up with. Is there a way to check that?

    Need help, LB7 no start

    So, you think that the injectors are getting the signal, but not firing as they are supposed to? How do I cap off one bank, what do you mean, disconnect the high side from the pump to one bank rail and cap it?

    Need help, LB7 no start

    I might be wrong on the extension language, tech said it was at 22, I thought that meant 22,000 psi. I will check that connection first thing this morning and re post.
