Need to verify your vacuum pump is providing vacuum to the system. Failing that, I would look at the switch on top of the transfer case that detects lever position.
I believe there’s already an electric fuel pump. It’s called a lift pump. It lifts the fuel from the tank and delivers it at low pressure to the high pressure injection pump. So that won’t help. No the R&R on the injection pump is more than an afternoon for the uninitiated. If you’re...
If you applied vacuum to the actuator and it moved, then the 4wd light should have stopped blinking at you should have been unlocked. If that is true then it’s vacuum plumbing or vacuum source or electrical wiring. There is a switch on the top of the t case that senses when you put I in 4wd...
That would be important to see and really verify. I suspect it actually is in front axle locked and isn’t disengaging which is the far more common condition. The actuator or solenoids typically fail in the lock position and don’t unlock. It’s also possibly your wiring is to blame, or the...
The vacuum tools are not too expensive, but you could try applying small pressure to the hoses and spray them with soapy water to look for leaks I guess. Yes the boot on the axle is attached to the actuator. I haven’t needed to grease mine yet so I can’t help much more than that. Good luck.
I went by there but unfortunately he can’t show target specs until the car is actually on the rack. The computer does t work that way. Sorry! I’ll look around a bit more for the print out but I may have tossed it.
If you changed the solenoids then this behaviors suggests a vacuum leak somewhere, or a sticky actuator. They need cleaned and greased and it probably never has been so it might be that or a cracked vacuum hose somewhere. Finally vacuum pump might be weak? Not sure. If you have a vacuum...
Yes the lights flash/solid based on the actual 4wd actuator position, nothing to do with vacuum or solenoids. If anything causes a failure for actuator to move (usually lack of vacuum or solenoid actuation) then it will flash.
Yes still drivable, you can remove that bar and drive fine. There will be a bit more body sway. If you can’t remove then tie the loose ends up somehow and limp it for a bit. It’s a large torsional spring that connects both wheels across. Some people remove them on purpose for more wheel...
