replace a LMM in 2008 Silverado with a LML engine
Welcome It's not quite that easy. The injectors are different along with the fuel pump and a handful of other parts. So swapping over the harness won't be the solution. I think the engine mounts might be slightly different. But possible to modify if I'm not mistaken You could swap... -
DEF Fluid in fuel tank
Welcome No idea on your insurance as that is going to be policy specific But you are correct about it not being very good. I thought I remember a thread years back about it. Rust and corrosion was a big issue with it. Along with the high pressure fuel pump not liking the lack of lubricity and...- 2004LB7

Horn ground
After looking at some diagrams. I think the upper steering bearing is used to pass ground. There is what they are calling a spring seat that passes the spring pressure onto the inner bearing race. I think this is the location where current is supposed to pass I found one post in another forum... -
Horn ground
I don't believe the clockspring pass the ground. As Brick posted in the schematic, the circuit passes through the turn signal cancel cam then to ground. But it doesn't show the ground going through a cam or clockspring I did find this on another forum "there's a ground pin on the turn stalk... -
Horn ground
Might need to attach a ground to the shaft with enough slack to accommodate the rotation if it's that bad -
Horn ground
You might want to poke your head in the wheel well and inspect the shaft. Might be a loose bolt or corrosion. If you pull or push the steering wheel to put pressure on the shaft, does it work any better? -
Horn ground
I'm pretty sure it grounds through the steering shaft Electrical diagram says "case horn" and "case column". I'm guessing that means ground the horn to the case. But as far as I remember. There is only one wire running up for the horn contacts -
Air in fuel, vacuum side is NOT leaking. Advice?
Primer bulb won't stay firm after cranking or running the engine. Primer is only hard when you have positive pressure on the output of the filter. Once you crank or run the engine it lowers the pressure or can even go into a partial vacuum. So the primer goes soft As long as as the lines stay... -

2027 more emissions....
One possible solution, ignoring the environmental impact of mining the raw materials, is having solar on peoples own roof that charges a powerwall for either carrying through the peak period or using it for EV charging. Many already have this so it is a viable option. Even if very expensive A...- 2004LB7

Motor missing and vibrating
P0606 is an ECM fault. Might just clear it and see if it returns. If it does right away then ECM might have some issues. If you have any monitors, foolers, tuners, etc plugged in, remove them first and see if it is ok afterwards. If you get the engine running fine then I wouldn't worry about it... -
P0016 Code
I'm not too familiar with these particular engines but from what I hear, you have to remove the transmission to grain access to the chain or belt or whatever they are using. Seems stupid to me if true Id look at another shop other then a dealership to get quotes and a second opinion- 2004LB7

Air in fuel, vacuum side is NOT leaking. Advice?
The injector return regulator.is connected to the return lines coming off the injectors. Each bank comes together at the regulator before connecting to the fuel return back to the tank. It's supposed to hold something like 58-160 psi on the injector fuel return in order for the injectors to be... -

Motor missing and vibrating
I'd thoroughly look over the harness, particularly the high voltage injector lines for any chafing or rub throughs. Also inspect the connectors and the pins. I don't recall if there are any known trouble spots to look for on the LML but others will chime in if there is any Do you have a... -
Air in fuel, vacuum side is NOT leaking. Advice?
As Josh said, there is a bleed point in the CP4 that can let pressure through the pump back to the tank. Or in your testing, from the return -
Air in fuel, vacuum side is NOT leaking. Advice?
Welcome Vacuum test your filter housing. If you've replaced all the seals I bet it's cracked and leaking there or the water sensor
