Oh, I will! This is a great learning experience, even if it is at your expense. :sick:
Best of luck to you! Hopefully tomorrow will turn out to be a good day.
At least it runs a little better, but it does not sound like the actual problem is found yet. :sick:
Truck starts, but will not idle or run at any RPM. However, by continuously pumping the gas pedal the engine will keep running up to 3000 RPM. Installed new fuel filter with no change in problem.
Doesn't appear to be the fuel pump.
Any suggestions will be much appreciated.
thanks, AJAZ
Thanks!
Pull and inspect every fuse, including fuses in the engine compartment fuse box......check to make sure that every slot where there should be a fuse has one....check that there are no blown fuses.....this might just be the cause of the 4x4 not engaging.
Next, check every wiring harness under the hood. There are a lot of them, make sure they are all plugged into something. Take each one and unplug it from whatever it is plugged into and take some wd40 and clean the connections, also have a box of qtips handy to wipe connections clean....
Next, get up underneath the vehicle and check the wiring harness to the transfer case (4x4 transmission). Make sure that the wiring harness is plugged into that transfer case. It's possible that the harness has a bad connection. Pull the plug and inspect for wear and corrosion. If it looks nasty then take some wd40 and spray the heck out of the inside of the plug. This a service tech at the dealer will charge you dearly for.
Next, visually inspect all of the front-end components for signs of wear, i.e. cv boots all torn up, sway bar unbolted, etc....
Prior to some point in the early 1990's GM used a thermal actuator switch to engage the front drive shaft. This little device would screw into the front axle from the top and it had two wires that protruded from it and they plugged into the actuator harness. The thermal switch caused a lot of problems for vehicles that were operated in cold climates because sometimes the actuator would not engage, leaving the vehicle stuck in the snow. In addition, the switch was prone to failure due to age, even if it had not been used all that much. So GM changed the actuator to a more durable electrical actuator that could be used in all post 1988 4x4's. Your vehicle may have an old thermal actuator. It is also possible that the prior owner may have had a problem with it at one point and had it replaced with another thermal. In either case, if the actuator is not working then the 4x4 will not engage, even if the transfer case is working properly......
Next, go buy a repair manual at your local parts store, it will save you a lot of money if you can do things yourself. Good luck!
I cann't find the fuses. there is a fuse box under the hood but the closes thing i could find in there was a brake light rely. I looked under the dash and cann't find any fuse under there.

Not sure if it will lend any help....

However, today on the way back from a weekend away, after about an hour and a half of having the cruise control on at about 85 the service engine soon light came on and the truck began to decelerate. It did not turn off. I pulled over and noticed no noises or rough idle or anything that would indicate a prob (all guages checked out fine). Upon accelerating the truck would not go higher than 65 mph or 2000 rpm. Is this limp home mode? It drove for about 45 minutes this way no problems and got me to the driveway. I went ahead and reset the computer (was this a bad idea?) and the light did not come on onupon restart. Any ideas?
How do you remove the rear interior door panels on a 3500? The door is stuck in the locked position and I need to get it open to see what is wrong.
Also the power door locking system does not work. It tries to, but it seems too weak to fully operate.
Any suggestions would be appreciated.
