I have a few ideas for you: 1) I know this sounds crazy, but try disconnecting the vehicle battery (both terminals) for at least 10 minutes, then reconnect them and try the remote again. 2) Replace the batteries in the key fob. 3) Take the circuit board out, wipe it down, and try again. Here is a video showing this process: How To Clean Your Key Fob Circuit Board 4) Reprogram the remote using these procedures: 1. Close all vehicle doors. 2. Insert the key into the ignition. 3. Hold down the power UNLOCK button on the driver?s door panel-continue to hold down until instructed to release in step 9. 4. Perform steps 5 through 8 in fairly rapid succession. 5. Turn the ignition switch to the ON position (as far as you can go without starting the engine). 6. Turn the ignition switch to the OFF position. 7. Turn the ignition switch to the ON position. 8. Turn the ignition switch to the OFF position. 9. Release the power unlock button on the door panel. The vehicle will lock and unlock the doors automatically. 10. Hold down the LOCK and UNLOCK buttons on the transmitter simultaneously until the door locks and unlocks. This step may take up to 30 seconds. 11. Repeat step 10 NOW for each additional transmitter (including any existing transmitters). 12. Turn the ignition switch to the ON position in order to exit the transmitter programming mode. 5) Order a new remote from us online at https://www.keylessentryremotefob.com/Chevrolet-Suburban-Remotes-and-Keys-s/3679.htm

Can be multi reasons search the codes and will have multi sites that give reasons and solutions for the problem --some reasons - dirty air flow sensor -failed or failing O2 sensor-injectors- fuel regulator- vacuum leak- coolant system/ sensor - needs tune up ect.

On this website you find fuse box diagram and description for Chevrolet Suburban (2002) https://www.carknowledge.info/chevrolet-suburban-2002-fuse-box-diagram/ https://www.autogenius.info/chevrolet-suburban-2002-fuse-box-diagram/

Forget about the fuel pump, completely for now. THAT is not the problem. Think on what you've told on the situation. Been getting worse hard to start as the temperature drops. Now here is the way the system works: Turn the switch on, the computer automatically jumps in to do what it does best, operate your vehicle/engine, by taking the impulses from ALL sensors, and setting the engine to a position that it will start and run properly. One of those impulses come from the temperature sending unit in the engine coolant system and, because it's cold, tells the computer to place the engine into "cold start" mode. Now you crank on the engine and it starts easily, because the temp sensor sent said pulse to the computer. Once the engine is warmed, this sensor sends a pulse telling the computer it is now warm and places the engine into "normal run" mode. As you can see, this scenario is with everything in proper working order. With your scenario, the engine will not start when cold. Therefore the computer is NOT getting any kind of impulses from the temperature sending unit/sensor. Meaning it's either bad or just disconnected and out of the system. These days you have to at least be as smart as the computer and diagnose things the way I do. Not saying I'm smarter than the computer, just that I outsmart it when needed. Now, Fix your Chevy.

I think that you are talking about the OBD Code P0446, here's the "official" word on the subject. I'm sure this will take care of it for you.

Condition
Some customers whose vehicles are operated in dusty type environments, such as farming or mining off-road type applications, may comment about the illumination of the instrument panel SES light, with a DTC of P0446 (Restricted/Blocked EVAP Vent Path) being set.

Cause
Dirt and dust intrusion into the EVAP canister vent solenoid, resulting in restricted air flow, may cause this condition.

Correction
DO THIS: Replace the EVAP vent solenoid with a more robust vent solenoid.

DON'T DO THIS: DO NOT Replace the EVAP canister or other EVAP parts.

After following the Service Manual diagnostic P0446 and determining that the EVAP canister vent valve is the cause of the SES light, replace the existing EVAP canister vent solenoid and bracket. This new vent solenoid has an enhanced filtering capability and a filter element that can be easily removed and cleaned. To ensure correct installation, follow the procedure below.

Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
Remove the bolt retaining the vent valve bracket.
Disconnect the electrical connector.
Disconnect the canister vent valve hose.
Install the new vent valve bracket, P/N 15105605, to the vehicle with the retaining bolt.
Tighten
Tighten the bracket mounting bolt to 12 N·m (106 lb in).

Install the new vent valve, P/N 10382105, to the bracket.
Reinstall the electrical connector.
Reinstall the canister vent valve hose.
Lower the vehicle.
Clear the DTC.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition.

Hope helps with this (remember rated this) Good luck.

Have you had the battery off ? if so the control unit will need resetting. this is in the manual. if the battery has not been off, take it off and leave off for half an hour and then put it back on and do the reset.

Plugged fuel filter? Going up hill will demand more fuel so maybe the filter is restricting high flow.

Depending on the age of your vehicle you may have a problem with the bulb sockets. I am assuming that you have checked the bulbs. Remove the bulbs and check for voltage in the bulb sockets with the brake pedal depressed. If there is no power then you may have to do some wire tracing looking to see if the wires have been pinched or cut by something.

stick shift or auto

You need the correct part. The part you have is for a different vehicle. No there is not an adapter you can buy, but you may be able to hard-wire it by cutting and splicing wires. I wouldn't recommend this, unless you live in a remote part of Alaska and have no other means to fix this.

Is that 125 Kilometers or miles?

You have a defective valve lifter or lifters.

The 4X4 is controlled by a electronic control module , without testing for codes an doing electrical test's would only be guessing ! Your best bet ,take it to a qualified repair shop .

If you disconnected the battery to change the fuel pump and did not disable the anti-theft feature first, you now know why it wont start. Check the owners manual if you have it, or contact a GM dealer to get the system reset.

Do you know how to do electrical testing with a volt meter ? There are videos on youtube on basic automotive electrical tesing . If you want to fix electrical problems there are thing's you need to know . How to read an use a wiring diagram , componet location diagrams , voltage drop testing etc.... Electric Testing Techniques You Need to Know Copy of Voltage Drop Essentials TST Motor Age How an where to find wiring diagrams , here at http://www.bbbind.com/free_tsb.html

It sounds like your security system it failing. I had the same thing happen to me. i took it to a shop and they wanted like $300 to fix it so i did some research and found a module that u can install yourself .check it out they have awesome customer service and if it dose not work they will refund you all your money no question asked.. i hope this helps ya http://vatspasslockpasskeysecurityhelp.com/ Do It Yourself GM Security bypass

their is no reset / inertia switch on suburban only fuses and relays ---will need to test fuses relays wiring connections and or pump for where failure is

Is there a security lamp on the dash that is on or flashing? Any applicable trouble codes? My info shows you have passlock, usually a fuel injector disable, only, may start and stall. If vehicle starts and stalls, leave key in the on position, If security lamp does not flash, the passlock system should not be at fault.
