I have 1999 GMC Jimmy. It had the 4.3 Vortec in it, would I be able to it out with 4.3 Vortec in a 1994 GMC Jimmy.


The engine will match up but the sensor plugs may not so you may have to swap the sensors between the engines.

I have a 1997 GMC Jimmy with a 4.3L Vortec V6. It will turn over but won't start. It's getting fire and fuel. All the dash lights come on when the ignition is turned on and you can hear the fuel...


On the vortec engines they require 56 pounds of fuel pressure to start a few pounds shy of that you have a dead vortec you will need a fuel pressure guage to verify

I just bought a 95 gmc jimmy 4.3 vortec with 4wd and underneather on the frontend differential there is a bar sticking out that is welded to stay out and my jimmy will not go into 4wd at all why and how do...


I don't know what the bar is for, but I can help you troubleshoot the 4wd. I have a 1996 4wd Jimmy. The 4wd didn't work when I bought it. Here is what I found. The vacuum lines at the rear of the engine compartment were soft and gummy and some were rotted. I replaced every vacuum line I could find. Hidden underneath the battery tray is a vacuum operated actuator that engages the front axle. This line was not connected at all. I popped the push button assembly out of the dash to make sure everything was connected and replaced the light bulbs. Installed the switch back in the dash and went for a test drive. Everything is now working as it should. Did the testing on a dirt drive. Never on dry pavement. There are also electrical connectors underneath the vehicle that must be checked. They are attached to switches on the transmission and the transfer case. Let me know if this helps you get your 4wd working again.

In a 92 GMC Jimmy, Where is the Fuel Pressure regulator?


If this is the 4.3 liter the fuel pressure regulator is located in the intake valley. You will need to remove the upper half of the intake manifold, once removed you will see a small round regulator located at on end of the injector line.
