SOURCE: 1994 gmc jimmy steering wheel removal

Gently pop off the horn cap / cover.

There will be a short wire attached, so be careful not to pull it too hard.

You will see the wire going into the metal frame of the steering wheel.

The wire will go into a "sleeve". Push the sleeve in, and turn slightly counter-clockwise to unlock the connector. The horn will beep a few times as you pull the wire out, just to warn you :)

You will now need a steering wheel puller. These can be bought for about $10 at any auto parts store.

Once the wheel itself is off, you will see a black plastic disk. remove it. Now you will see a metal disk with notches in it (this is what locks the steering wheel when you turn the key off). You may want to get someone for assistance for this one, as there is a pretty stiff spring behind the disc, so use caution. You will need to push the disc towards the dash and remove the retainer clip.

Once that is off, you will see the white turn signal switch. Remove the hazard switch button first, then the turn signal lever retaing screw (be careful if it has cruise control, as the wires are thin and delicate), then remove the 3 phillips head screws holding the actual switch on. Let the switch hang out of the way.

Now, you'll see the lock cylinder retaining screw. This is where you may have a problem if you don't have a key.

After removing the screw, you MUST turn the ignition switch to the "run" position and pull out the assembly.

SOURCE: fuel pressure regulator

How do you know that it is the regulator?
these 4.3 motors had a lot of trouble from 93 to 98, I know I had 2 of them.
What happened to mine was that the intake kept getting very carboned up. After I would clean it, the truck would run fine for about 5 or 6 months, then same thing.
Theres actually a class action lawsuit about this that I believe has been settled, you may have recourse if you bought it through a dealer. Good luck.You'll need it.

If it's a manual transmission, it's the bushings under the gear shift that a beat out of it. If it's an automatic, check you fluid level and filter. It may not be able to build enough pressure in the tranny if the filter is clogged or isn't enough fluid.

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 1994 GMC Jimmy 4.3 vortec 4x4 automatic, and the transmission started to slip, then the battery died, we got it home and it wouldn't start, so we charged the battery and it ran fine for abou


You may potentially have an serious electrical drain in your car circuits. The drain is slow and continuous, draining your battery charge even if you do a start. Check the cabling and look for load on your battery with a Volt meter to check for any charge drainage. Check this as a precaution before replacing any more parts.

What is a Vortec engine?


The "spider" injector is the problem. You're right that one of the injectors is stuck open, unfortunately it has to be replaced as an assembly. This a common problem on the Vortec V-6's. When you were checking the fuel pressure, the fuel was passing through the open injector, giving you a low reading. After replacing the injector assembly, be sure to change your oil before you start the engine. I'd be willing to be you have a pint or two of gasoline that has gotten into the crankcase. That injector unit will cost you around $350. It's not too hard to put in, just be careful.
