How do you replace 2000 GMC Jimmy fuel pump?
You need to drop the fuel tank to get to it. Then it unscrews.
There is more to it then that...
MAKE SURE THE TANK IS AS EMPTY AS POSSIBLE! If you have alot of gas in there, I would suggest syphing as much as you can out of the tank!
If you are doing this yourself, you wanna raise the back end of the vehicle as high and as SAFETLY as you can.
Support the tank with another jack and remove filler neck hose from the tank.
Remove tank staps and slowly bring the tank down.
Remove wiring harness from the fuel sending unit/
Remove plastic fuel lines from the sending unit. BECAREFUL not to break any of them. If you are doing this in colder weather, I would suggest doing it in a garage or having someone with garage do it for you. Cold weather COULD cause the lines to snap and you'll end up with more of a headache.
Twist out your pump.
Install the new fuel pump and gasket.
Follow the directions in the same manner only in reverse.
Start vehicle and check for any leaks.
Took me a few hours....but if I can do it....you can too :-)
It could be several things. First does your fuel pump run when you turn your key to the on position? It should run for about 2 seconds and you should be able to hear it. If it doesn't that's probably your culprit. If it runs you could have gas line freeze or a clogged fuel filter possibly clogged or dirty injectors.
How do you test the fuel pump on a 1997 GMC Jimmy?
Listen for a hum from under the middle of the vehicle when you turn the key to the on position. If you hear a 2 to 4 second hum, then the fuel pump is most likely working. If your vehicle has fuel but will not start, replace the fuel filter. If there is no hum, check the fuse first.
How do you bypass the ABS on a 1994 GMC Jimmy?
Why would you want to do this? ABS have saved me more than once. Practice using them and leave them alone. They are a great safety feature. If you do not think so then all I can say is that you are dead wrong and I will not help you disable your ABS. ABS allows you to keep control while under full braking and still be able to steer around trouble. On the other hand if your ABS has failed and is not working properly, then you still have regular braking ability and there is no need to try and bypass the system.
The EHCU can malfunction and cause brakes to go out, replacement is $1300. Or you can bypass the EHCU and save money. The EHCU has 2 lines going into it and 3 out. The 2 "in" are from the combination valve, 1 for rear system and 1 for front system. The 3 "out" are split into 1 for rear brakes and 2 for front brakes. For the rear system, all you have to do is connect the rear out from the combination valve to the line that once connected to the EHCU for rear brakes. Front system. From the front out on the combination valve, install a T in the line. The 2 ends of the T connect to the lines that used to go to the EHCU for front brakes.
How to bleed Air lock in the heater core?
The engine temprature was low around 50 Celsius and had poor heat from the heater, I replaced the thermostat on my 2005 Jimmy and topped off the coolant levels. Everything seem to come back ok, Engine runing smoothly with good heat and engine just below 100 degree celcius. Then a couple of weeks later we got some real cold weather and ther was just lukewarm air coming from the air vent, engine still at 100 degree.with the engine turned off and just warm, I cut the return hose from the pump to the heater core spliced in a flush kit (hoses where empty) and proceeded to raise up and fill the the hose with premixed coolant DEX Cool. Had a few bubbles come up as I was filling and when it topped off i put the washer and cap on the bleed kit and drove the car for 20 minutes with good heat coming from the vents now.
Hope this helps
What is the easiest way to change the spark plugs on a 2000 gmc jimmy?
i think that the chassis and suspension is the same for 1987 through date. so, the easiest way that i have found to change the spark plugs, if it is a v-6, is to jack it up, remove the front wheels and use the little access cut-out in the fender well to get to the plugs. on my 93, the steering arm is right above the area that even a wobbler won't get into. have fun!
How do you replace the Rear o2 sensor on 2000 gmc jimmy 4x4?
Remove the vacuum hose from the O2 sensor. Remove the wiring harness. Remove the O2 sensor retaining screws. Reverse the process to install the new O2 sensor.
Where is the starter located at on a 2000 gmc jimmy?
My 2000 GMC Jimmy is slow cranking. The battery voltage meter is showing charged so I am assuming that the starter is the problem. Where do I find the starter to remove it?
How do you change the spark plugs on an 86 GMC Jimmy?
First obtain new spark plugs. Then set them to the correct gap as specified on the VECI label. Once gapped, coat the ends with silicone dielectric grease.
Next, remove the wires from the old plugs. Grab, twist, pull. If a wire breaks, replace all the wires as any fragility indicates a chemical breakdown of the insulative material.
If the engine is hot, wait for it to cool down fully.
Use a 5/8 inch to unscrew the old spark plugs. Some or all plugs may be easier to access through the wheel wells (with truck jacked up off the ground) than reaching down through the hood opening.
The second plug on the driver's side may be difficult to access due to interference of the steering column intermediate shaft. If so, you can either use a floor jack and wood to raise the engine by the oil pan, or use an open end wrench to turn a short plug socket, or use a swivel-type spark plug socket.
Screw the new plugs in place where the old ones were. Reattach ignition wires.
It is usually a good idea to replace distributor cap and rotor when replacing plugs on this truck. PULL THE WIRE OFF THE ONE YOUR REPLACING. The plug you are replacing is the wire you pull off. This way you won't put the wrong wire back on the plugs, AND CAUSE MORE PROBLEMS.
How do you test a vehicle speed sensor?
No need to test VSS. If the check engine light is on and fault code is VSS; then replace same. Huge job best done by reputable shop.
Where are the soft plugs in the 4.3 1997 GMC Jimmy engine?
They are part of the engine block and apparently you have to hoist the engine up so you can move the axle out of the way to get to them The two types of plugs are alongside each other, both just above the pan rail on each side of the block. The drain plugs are screw in plugs which look very much like normal pipe plugs (which can in fact be substituted, they use pipe threads). They have either a hex head or a square head, I've seen both types. Usually they are either 1/4 or 3/8 pipe thread plugs, (which means they are 1/2" to 5/8" OD). They are for the purpose of draining coolant out of the block, and should be opened when ever you are trying to flush all the old gunk out of a car's cooling system. The core plugs, AKA soft plugs, AKA freeze plugs are in the same area, but are much larger, about 1 1/2" diameter, cup shaped, and press fit into holes in the block. There are 3 per side on Mopar blocks of this era. They have to be removed carefully, and there are at least two ways to do this. One way is by cutting them through the center with a very sharp cold chisel (be careful not to drive the plugs through the hole, they can drop down inside and be difficult to retrieve), and be careful not to smack the plug so hard that you damage a cylinder jacket, which is right behind some of them. When you have cut a large enough hole through the center, grab the remains with a good channel-lock or vise-grip and twist and turn the bugger until you work it out of the hole. They are tough, but once you've done one, you'll get the hang of it. The other way to do it is to drive one edge of the core plug into the block so as to get the plug to tilt out from the opposite edge, then grab that with your channel-locks and twist and pull it out. It helps to know how deep you can drive an edge in, and this is dependent on how close the cylinder bore is to the plug. You can sight down from the spark plug and see what is behind each one. If you do one that is between cylinders, you don't have to worry about hitting anything. If you do one that is right on a cylinder, you may hit the cylinder jacket before you can get it to go in far enough to tilt out the opposite edge. You'll just have to experiment with each one. Stay with it, you can do it! You install new ones by cleaning the holes carefully to scrape off all the old remains and rust, then put a skin coat of RTV sealant on the outer sealing surface of the new plug, and drive it into the block (NOT TOO FAR!) with a socket and breaker bar that fits well so you can tap on the end of the handle to drive it in squarely until it fits like the original. You'll find they are available in either brass or steel. I use brass for all but the center plug on each side (the brass is forever, the steel is to be a sacrificial anode and protect the block if you ever get lax on your anti-corrosion protection.) I put the steel one in the center position because it is the easiest to change.

How do you replace heater core on a 1999 Lincoln Town Car?
The question you ask is too involved for a proper answer. You need to go to a car parts store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.
What wheels will fit my 1996 GMC Jimmy?
round ones, 215/70/15 I believe. Check the drivers door(next to steering wheel) for a sticker.
If there is no heat in a 1996 GMC Jimmy what might be the problem?
I'd start with thermostat and heater core
Answer"You have no heat" is a pretty ambiguous question. There could be a lot of things going on. The first answer is a good one, try the thermostat. While you're at it, I would also suggest flushing the cooling system. You have to drain the system to take care of the thermostat anyway. Buy some cooling system flush, and have at it. When you refill the system, be sure to use a 50% - 70% mix of Dex coolant to water.
If that doesn't work, you may want to try the heater core. This is a big hassle, as the heater core is buried below the dash - which means you have to pull the dash out. The jobisn't hard, but it is a pain in the rump and time consuming.
On the other hand, if the problem that the blower isn't blowing, you're into a whole different issue. My 96 Jimmy's blower turns on an off seemingly at will. The warmer it is outside the more likely it is to work, which is a huge drag. My heater core went bad, so I changed that, as well as the thermostat, and heater controle module. Still no good. This leads me to the conclusion that there is either a loose connection in the wiring harness, or a problem with the blower itself. I think that it's the wiring because if I whack the dashboard, the blower will sometimes turn on.
Before starting any project, get a good manual (I use Haynes) and read it thoroughly. You will be glad you did, and the book will more than pay for itself in no time!
Good luck. -- Mr. Dog
What is the bolt pattern on 1988 GMC Jimmy?
The "5" designating the number of lug holes and the "4 3/4" designating the measurement in inches from the center on a lug stud, then skipping a stud, to the outside edge of another stud.
This is the same bolt pattern Chevrolet started using back in 1949 on their passenger cars and was used on the full sized passenger cars until 1971 when they went to a 5 on 5" pattern on the full sized cars.
Then in 1977 they reverted back to the 5 on 4 3/4" pattern on the full sized cars with the exception of station wagons which some had the 5 on 5" pattern.
NOTE; I don't know the bolt pattern of the "newer", rounded body style of the RWD full sized platform.
The Camaro used the 5 on 4 3/4" from it's introduction thru at least the 3rd generation. I don't know what the new Camaro pattern is.
If the 1988 GMC Jimmy in question is 4 wheel drive then it is possible to use wheels from a 2 wheel drive, though the wheel/tire combination will stick out further away from the hub and make the combination stick out further from the body. While this make work, it's not really recommended as the extra leverage on the front wheel bearing assembly can cause premature wear. Plus there may be tire to fender rubbing because of the different offset of the wheel.
How do you change the steering wheel?
Take the nut of the steering wheel under the horn and use a puller to get it off
