2001 GMC Jimmy - Answered Questions & Fixed issues

I'm not sure I am understanding your question. The low Fuel indicator light comes on, depending on how sensitive it is set, when you have between 2 and 5 gallons of gas left in the tank. This also depends on how accurate your fuel level sending unit is reading the fuel level in the tank. The low fuel level light depends on the level of fuel in the tank itself but other than using that sensor it has nothing to do with the fuel gauge itself. The fuel gauge may or may not be accurately showing the fuel level.

Have you tried to turn the stearing wheel side to side while turning the key? Sometimes the wheel gets bumped and it locks with the key in the ignition and the added tension won't alow you to turn key unless you turn the wheel from one side to the other.

Poor design of spark plug distributior, moisture builds up and doesn't fire properly. Drill small holes in bottom of plastic holder. And seal with heat resistant sealant. And Change the plugs going from EGR valve. They Wear out. Use fuel cleaner Heet when putting gassing up moisture builds up in tank. I have 2000 jimmy, it eventually solved the problem. Change gas too. Basic maintenance too. ET NY.

I would disconnect the battery, and see if you reconnect it disingages, or resets. Just a thought. Otherwise check YouTube...ET NY

Need to put fuel cleaner, treatment " heet " from auto store. Moisture in tank. Also, carborator retains water. Must drill small holes on bottom of plastic cover. Water gets in and the spark plugs don't fire. Then seal the carborator with heat resistant sealant. Check or change the electrical connections to the EGR valve. It worked for me after these are done. Poor design of carborator on this vehicle. Eileen T. NY

Call the dealer with the vin number and they can give you exact spec's

Check battery voltage is >11.5VDC. Connect an incandescent automotive test lamp to battery positive and probe the engine block. If it doesn't light or is dimly lit, poor ground

You still have a problem with all the O2 sensors Bbank 1 Sensor 1, Bank 2 Sensor 1 and Bank 2 Sensor 2) - if they are all the correct ones and are correctly installed and connected, then you need to carefully check the wiring harness and wire connections from them to the ECU. the P0300 just means random engine misfires.

What is a "teach" That said you have an engine misfire, have the engine control system scanned, it will give a code showing what cylinder or cylinders are misfiring.

IF the light is on and flashing, there's a trouble code stored in the computer. Get the code read. Do NOT buy this vehicle until you know exactly what's going on.

There are doors in the plenum that open and close to redirect flow.There are vacuum and electric motors that control them or could be your switch.

Is the check engine light on? See what it says. It may be transmission related. The leaking fluid is probably transmission fluid. If it's really low you'll have a problem.

hi. not sure if this link will help you out but have a look. 2000 GMC Jimmy is smelling strongly of gasoline Google Search

It may be the switch is failing and needs to be replaced. However, it is not unusual for the motor moving the seat forward and back to jam on the running teeth attached to the seat. If, when you use the switch, you can either feel or hear the motor trying to run, then it is probably a mechanical problem under the seat. This can have a few causes - something on the teeth that should not be there, alignment of the motor to the teeth (maybe loose bolts), etc. If this is the case, the only way to troubleshoot this is to remove the bolts holding the seat frame to the floor, then using the motor move the seat as far back as it will go, then tip the seat forward and inspect the motor and gears underneath.

Can you turn the crankshaft by hand? Use proper size socket and breakover, hopefully, there is a pulley bolt on the end of crankshaft. If it won't turn, take the belt loose and remove spark plugs in case of hydrostatic lock, fluid in the cylinders. You said it locks-up, that what I am going by. Meaning the engine mechanically locks up. It could be internal engine problem?

I don't believe there would be a problem due to fit but this is difference in measurements. The 75 diameter (across tire) is 28.88 in. The 70 diameter is 27.95 in The 75 width of tire is 9.25 The 70 width is also 9.25 The 75 circumference 90.72 The 70 circumference 87.82 The 75 sidewall height 6.94 The 70 sidewall height 6.48 The 75 revolution per mile 698 The 70 revolution per mile 721 The 75 speed at 50 and the 70 is 48.4 I can't see why it would not work.

Hello Cjmm, Your vehicle presently has 37 Technical Service Bulletins (TSBs) Driver Amenities: Instrumentation.. None specifically point to your issue (not even looking at "tow" issue)... but the associated wiring clearly depicts "a continuous battery source"... which should supply continuous battery during ignition key operation...!! >> Assuming all battery & ground points are clean (battery cables & post connections are the FIRST step in ALL ELECTRIC anomalies)... >> The NEXT is Fuse terminal ("hot at all times") Fuse 19, 15 Amp RDO Battery is your IPC (INSTRUMENT PANEL CLUSTER) source on your vehicle's wiring diagram. FREE wiring & TSBs are available (after registration) at BBB Industries website for most POPULAR USA market vehicles (I am using it now to verify your "IPC" connection). See BBB Industries (at bottom): After FIRST cleaning your battery terminals... Place FELT WASHERS to prolong protection: Amazon com Road Power 0989 Anti Corrosion Fiber Washers 1 Pack 2 Washers 6... Amazon com NOCO NCP2 CB104S 4 Oz Brush On Oil Based Battery Corrosion... ... and remember those cables have two ends... Them move on to inspect that fuse ... Amazon com Bussmann DIA 2 ATM Blade Fuse Diagnostic Kit Automotive Hope this helps Carnac the Magnificent

I would recommend replacing the idle air control valve. Refer to any of the many YouTube videos on this subject and you shousl have no problem replacing it. It is availabe at Rock Auto, Parts Geek and most good local parts shops.
