You need to pull the Heater/AC control and check to see if the mode control switch has vacuum going into it, if not, find out why, the hose goes to the engine through a hole in the firewall on the passenger side, trace the hose, you will see it in that area, follow it to the engine.
Was the truck the smae year and model? it may look the same on the outside but the be wiring differently, without holding both and looking at them there is no way to tell, did you think the used guage may be defective? did you test the wiring to the guage?
Usually somewhere on the engine or in the engine compartment, there is a sticker with the engine specifications. The spark plug gap should be included. If not .032 or an inch should be close.
Good luck
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.
On a small block Chevy, the dipstick is a press in fit. I put silicone where the tube meets the block (bottom of the flare) and let it sit over night. This has worked for me. Good luck!
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.
If your vehicle seems to be running fine but picks up speed slowly, check to see if you have a check engine light. Having that light can point you in the direction of the problem. Also check to see if you have a bad catalytic converter which can clog your exhaust causing back pressure to the engine and cause your vehicle to pick up speed slowly or feel like it has no power. I hope this helps. Have a great day.
The code doesn't tell you what to replace just that the computer thinks there is a problem on that system. Did you check sensor wiring circuits? Black wire should be ground--gray wire--ref voltage about 5 volts. The lite green wire signal to computer. The map sensor also needs vacuum.
Use a digital multimeter on signal wire, engine idling. What is the reading? Just for comparison, at idle the tps and map signals should be close to the same reading, won't be exact. If several volt difference that isn't right. In my opinion.
The way to a fix is to view wiring diagrams an use a DVOM - digital volt ohm meter an test the electrical circuit's . If you don't know how to test automotive electrical systems like this , not just replacing part's , your best bet , take it to a qualified repair shop .
Or learn how too do it correctly .

when I press the brake pedal my parking lights come on ????? To me this sounds like a ground issue , voltage back feeding through the circuit looking for a ground . view the turn signal wiring an test at the back of the vehicle ,turn signal wiring using voltage drop .
