My h3 had no oil! Knocking badly, Is it ruined?
What is the make and year of your H3. The damage will depend entirely on how long it has been used with no oil. Can you hand crank the engine two or more full rotations? If is has only been a very short amount of use the engine should be ok. It will only be badly damaged if it has been used dry for a long time.

The best thing to do is visit your local wrecking yard. They should tell you what can be switched and what problems you might run into.

2005 F150 No shift when lights, a/c or other electrical accesory turned on. Diminished functionality
a DC power problem., lots of tests, I will just list them all.at least a voltmeter tool is needs a $15 investment that pays back ROI every time it is used.1 : Alternator test fails or its belt is loose .2: someone fiddled about the ATHERNATOR big RED wire, and blew out the MAIN alternator fusestep 1, alternator swap is remove battery NEG lug first of blow that up.3: battery no good, (told now it is new) 4:wiring bad or lugs rusty, on battery cables or alternator.5: a charged battery can be load tested easy, (a simple cheap tool )6: a battery not charged up first and fails load test is the car drained the battery . ( bad for battery this is)7: a new battery charged up must pass the load tester test.alts have 3 failure modes not 1.dead totally , 11vdc , when engine idles. (as classic answer , endless )bad AC 3 phase diode bank inside such that only 35amps not 110amps now. and huge noise !bad Alternator regulator regardless of where it is locked, (3 places in 100 years)end.oops one more fuses bad , even the Alternator has a fuse.huge fuse and is blow by folks swapping ALT with battery lug (neg minus) not pulled first.some F150 have 87amp alt and only do 45amps at idle.or 1/3 that bad, 15 amps, will not run the car proper under load nor save the a battery from destruction.the ALT performances is in the service manual to read. and I will put it below 2005 specd

My 2008 Kia Spectra won't start
Probably one of the main fuse blew. Start by removing foiled fuse. Use a 12 v light tester and check main fuses first. Might as well check all the fuses. Replace as needed.

Can the problems associated with code P2127 on a 2010 Chevy Impala cause a/c not to kick on?
DTC P2127: Accelerator Pedal Position (APP) Sensor 2 Circuit Low Voltage
This is right out of factory service repair manual , don't google stuff may not be accurate.
If you look under the steering wheel at the gas pedal you will see connectors at the Accelerator Pedal . position sensors inside gas pedal .
The throttle actuator control (TAC) system uses two accelerator pedal position (APP) sensors to monitor the accelerator pedal position. The APP sensors 1 and 2 are located within the pedal assembly. Each sensor has a 5-volt reference circuit, a low reference circuit, and a signal circuit.
Two processors are also used to monitor the TAC system data. Both processors are located within the engine control module (ECM). Each signal circuit provides both processors with a signal voltage proportional to pedal movement. The processors share and monitor data to verify that the indicated APP calculation is correct.
It's not see wide open throttle like other guy says .
The ECM detects that APP sensor 2 voltage is less than 0.16 volt for greater than 0.5 second.
Action Taken When the DTC Sets
• DTCs P2120, P2122, P2123, P2125, P2127, P2128, and P2138 are Type A DTCs.
• The ECM commands the TAC system to operate in Reduced Engine Power mode.
Anytime the vehicle goes into reduced engine power mode A/C shuts off - cruise control won't work etc..
Just change the gas pedal assembly .
