2003 GMC Sonoma - Answered Questions & Fixed issues

Maybe there are videos on youtube showing how .

Powertrain Control Module (PCM) On the right side of the engine compartment

If compressor is not kicking in, low pressure will be too high. If Compressor IS kicking on, orifice tube may be blocked, or compressor may be bad. You need a full manifold set to work on AC, not just the gauge that comes on a refill can.

Sounds like you have a blown fuse or relay

What makes you think the IAC is the problem? Highly unusual to change this valve as much as you have in the time fame indicated. What are the symptoms?

fill until it runs out of the fill hole

Sounds as if the ignition cylinder has an internal problem. You may have a sticky wafer inside the cylinder. You can try using some WD 40 and inserting the straw inside the cylinder and giving it a good spray. You can also try gently rocking the steering wheel back and forth while trying to turn the key. With out the ignition cylinder turning, the gearshift will not come out of park nor will the steering wheel come unlocked. Hop this helps

The filter is located by the driver side underneath the truck. Following the fuel line coming out of the fuel tank will also help you to find the filter.

Driver's side of truck on the inside of the frame rail in front of the fuel tank.

Motor Burnt out , they don't last long , and they just die on you, any time

That should not have happened ! Did you disconnect and forget to reconnect, or otherwise damage, the security wires running to the ignition switch ?

well is the fluid discolored brownish looking instead of red or rose pink if so it might help a little if its like described there's something wrong the cooling system is not cooling it off the right way running hotter then normal there could be a broken vacuum line causing the late shift and that will make the fluid burn you could be hard on the gas and this makes a transmission shift late and on an old truck that's 13 years old now released in 2002 and the combo of not changing it for long periods of time /driving habits/cooling the fluid the lines go through the radiator to the trans cooler that's inside it this will take down a transmission in a short time that's brand new and will surely destroy and older one but maybe there's a chance you can catch it before its ruined and give it life till the summer

Could be a bad one even if its new it happens

TRY ASKING N AUTO PARTS STORE

You have a plug wire crossed check the firing order, you can look on the net for your make, model and engine size to locate the correct order. I hope this helps. Take Care.

make sure battery has full charge and alternator is charging properly, all connections good. I'd use digital multimeter to double check voltmeter. If idle issue, I'd check and clean anything that has to do with idle air system. Clean throttle bore, around throttle plate, clean small passages in throttle body, check and clean iac. Any applicable trouble codes? If you have the spider fuel system, that system is noted for problems. good luck

I DON'T KNOW. LOOK TO SEE IF THERE IS ROOM TO MOVE TIRES OUT A BIT. YOU COULD USE A UNIVERSAL RIM SPACER. EXPENSIVE BUT TRADING FOR A DIFFERENT TIRE PROFILE OR DIFFERENT RIM WITH LESS SET BACK MIGHT BE CONSIDERED. SOME OLDE OLDS HAD DIFFERENT OEM RIMS TO CLEAR CALIPERS.

It could be a leaking fuel injector or a bad fuel pressure regulator. Do this plug the fuel return line then turn the switch on then off, if the pressure holds replace the fuel pressure regulator. If the pressure bleeds down remove the fuel rail with the injectors still attached and see which ones leak. I hope this helps. Take care.

I could suggest you count them, but if you have the right parts they should fit together just fine. We can thank Eli Whitney and Henry Ford for creating standardized parts. https://www.partsgeek.com/mmparts/history_of_the_assembly_line.html

Removing front bumper is easy. Look under the bumper. There are bolts holding it to the frame. Unscrew these and bumper will come of lose. Screw new bumper same way you unscrew the old one. Remember don't titen screws right away. You have to adjust new bamper so visibly floats with fenders and front grill. Than titen up bolts.
