Leaking fuel pressure regulator , or leaking injector's ,depends on injection system . ! it's only running rich on right bank. whatever that means . Your vehicle is a v - 6 has two banks . right side of the engine an left side of the engine . Bank 1 is where #1 spark plug is . bank 1 is odd numbers 1-3-5 Bank 2 is even firing #'s 2-4-6 . What fuel injection system does it have ? Your best bet mite be to take your vehicle to a qualified repair shop.

no,you will need to siphon the gas out of the tank.before you do,remove the gas cap,have someone turn the ignition on,while you stand by the tank.the fuel pump should run for a second or two. if it does ,I doubt it is the fuel pump,if it does't,it probably is

The Ignition Control Module is located: Under hood, center, rear engine area, mounted in distributor

Check connection on brake switch and test with multimeter.

The leak at the electrical plug.. can you tell if its coming from around the edge(s).. or coming through the wires them selves(around the wires)..If you just want the leak to stop, you could remove the plug and replace the o-ring or what ever type seal is there... If its coming through the wire area (wires themselves),, you can use some devcon 2 ton epoxy..(clear and liquid you mix) DEVCON 2 TON EPOXY 84fl oz SYRINGE Walmart com .. about the length of the dipstick..not sure.. a "junk yard" may have one cheap...

Sounds like bad ground

Could be one of many things. Have you check the catalytic converter? This will get loud, but if you can remove the O2 sensor before the cat try to repeat the fail. This will relieve the back pressure. If the problem goes away you probably need a new cat.

It's the check vale inside fuel pump module . Testing for failed fuel pump check valve

If it is the water pump there is a weep hole on it. That may be where it is leaking. Or it could be a frost plug.

if it's carburated, make sure your butterflies are opening.

I was given a 1994 s10 Chevy Tahoe vortex blazer??????? It's either a S-10 pick-up or it's a Tahoe or a Blazer not all three . So which is it ?

probably the injectors are not working run the fault codes or have the injectors for those cylinders checked check wiring connections for the harness

Front drive shaft? Look to the front differential. Rear shaft shouldn't turn at all on the ground. Then look at the T case.

trenamission is broken, get a new car

did you bleed power steering pump?!

Sounds like a freeze plug
